- Supergirl: 24 storage rooms and still no mirror.
- Zor-El: [elsewhere] Kara! Nxyly! I found it!
- [a crashing is heard, and Zor-El screams]
- Supergirl: [finding him on the ground holding his ankle] What happened?
- Zor-El: It was the prisoner with the scar that captured me.
- Nxylgsptinz: He must have been following us. He attacked your father and then he tried to take the mirror, but I chased him off. I knew we shouldn't have split up.
- Alex Danvers: There's a cold signature forming at the Noonan's in Grand Central Station. I'll monitor it from here.
- Brainiac-5: [taking the Prototrap] May I?
- Lena Luthor: Brainy, aren't you gonna want instructions?
- Brainiac-5: I'm a 12th-level intellect, Lena. I think I'll figure it out.
- Zor-El: [comforting Kara] This is getting to you. I can see it. The Phantom chills, the terror, it's becoming too much.
- Nxylgsptinz: Don't be such a killjoy, Papa El. Because I think I found what we're looking for.
- Zor-El: [joining her and seeing across the ridge] The Anchor.
- Supergirl: [taking his hand] We're going home.
- J'onn J'onnz: M'gann, you should be resting.
- M'gann M'orzz: I had a vision of Prime Phantom's lair. I think I'm still connected to the hive mind of Prime and his progeny.
- Dreamer: How is that even possible?
- Brainiac-5: When J'onn transfused his piece of M'gann's soul back into her, it was just that, a piece, and not the original soul in its entirety. I estimate M'gann is still about 18% Phantom.
- J'onn J'onnz: I hate that you're still linked in any way to his kind.
- M'gann M'orzz: But don't you see? It's good news. Phantoms have the power to sense a person's life force. That means that I have that power, too. I can use it to hone in on a specific life force anywhere, even in the Phantom Zone. I can find Supergirl.
- Alex Danvers: Are you serious?
- Lena Luthor: We're gonna bring Kara home.
- Brainiac-5: It also means that M'gann can use her power to sense the life forces held captive in the Prime Phantom's lair. There's a 99.999% probability that once we find and release them, they'll immediately return to their rightful owner, thus restoring the progeny.
- J'onn J'onnz: Brainy, Prototrap.
- M'gann M'orzz: Watch out for his talons.
- Brainiac-5: [trapping a Phantom] Should've stuck to decaf.
- M'gann M'orzz: [indicating the woman the Phantom attacked] Look. Her life force is leaving her.
- J'onn J'onnz: [watching it zip away] Track it to Prime Phantom's lair.
- Alex Danvers: Hey, thanks for backing me up.
- Lena Luthor: No, of course.
- Alex Danvers: Okay. So, what are you thinking?
- Lena Luthor: Q-waves. I used them to replicate Malefic's powers. I think I can do the same with M'gann's sensing abilities.
- Alex Danvers: And the nanobots?
- Lena Luthor: I'm gonna task them to map the brains of the progeny in containment to create a device, but even if I'm able to do that, I'm gonna need a piece of Kara's DNA to calibrate the device to the right frequency in order to track her.
- Alex Danvers: I know where we can find some.
- J'onn J'onnz: Brainy, we've got five Prime Phantom progeny in containment. It's getting a little crowded down there.
- Brainiac-5: I'll prepare another containment unit.
- Alex Danvers: How many containment units does that make now? Is that four? Supergirl would have stopped this by now.
- Supergirl: Family isn't about blood or last names. It's about the people who love you for who you are and stand by you no matter what. And just as my sister Alex has always been there for me, so have my friends. They're my family, too. Anything is possible when you have family who love and support you.
- Lena Luthor: It's so amazing to see and hear Kara. Feels so real. I mean, I know she's not here with us, but...
- Alex Danvers: She'll be here soon. I know it.
- Supergirl: We may not always agree, and at times that may break us apart, but in the end, we always come back together, stronger than ever.
- Alex Danvers: Hold on, sis. We're coming.
- [taking the crystal out and offering it to Lena]
- Alex Danvers: The core of this crystal contains Kara's digital life force. I would like you to use it for the device.
- Lena Luthor: What?
- Alex Danvers: You said you need a piece of my sister to track her in the Phantom Zone.
- Lena Luthor: Yeah, but if I extract that, you'll lose the recording forever.
- Alex Danvers: Well, what matters most is that we get back the real Kara. And you said that life force can do that, right?
- Lena Luthor: Yeah, I mean, I hopeful, but there's no guarantee.
- Alex Danvers: [putting the crystal in her hand] I trust you.
- Lena Luthor: Thank you. Um... I'll let you know when I'm done.
- Alex Danvers: I'm gonna stay. I would like to help.
- Lena Luthor: [giving her a pair of safety glasses] Well, suit up.
- Zor-El: I think my ankle is broken.
- Supergirl: Okay, don't move.
- [pulling a chair closer and helping him sit down]
- Supergirl: Okay. Slowly. Nyxly, can you do anything to help?
- Nxylgsptinz: I'll try.
- [snapping, nothing happens]
- Nxylgsptinz: My magic is still depleted. I'm sorry. I don't know why I can't get anything right today. I never should have left the two of you alone, defenseless. I could have prevented this.
- Supergirl: No, this is not your fault. It was my decision to split up. You saved his life.
- Supergirl: [straining to force open a door] Sorry. I usually have super strength. I can just kick those down.
- Nxylgsptinz: Are you sure this is right? I mean, wouldn't it be too obvious if they put the exit where you'd expect it?
- Zor-El: The other buildings are barracks. Supply room is built for the Fort Rozz prison guards.
- Supergirl: I know it's in here. It should look like a mirror.
- Zor-El: That only the righteous can activate. Instead of a reflection, you see your home... and walk right through.
- [Kara touches a wall panel and the room's lights turn on]
- Zor-El: [spotting the exit] Oh, no.
- Nxylgsptinz: What? What's the problem?
- Zor-El: Kara, activate it. I need to be sure.
- [Kara puts her hand on another panel to scan her palm]
- Zor-El: What do you see?
- Supergirl: Just us.
- Nxylgsptinz: It's not working.
- Zor-El: I was wrong to have hoped.
- Supergirl: The exit can't be broken. Not after everything we've been through. Nyxly, your magic. Can you fix it?
- Nxylgsptinz: I'll try.
- Zor-El: [as she snaps, nothing happens] I knew this was a waste of time.
- Nxylgsptinz: What, you're just going to give up?
- Supergirl: Father, please. Please, think of everything we've accomplished already. We... we made an ally where there were only enemies. We found magic where there was only misery. We found each other after decades apart. We can't give up now. Not after all that.
- Zor-El: What else is there to do? The mirror can't be fixed.
- Supergirl: Maybe not, but you knew Mother better than anyone. And you know she never would have left her guards stranded, so... so think. What would she have done?
- Zor-El: She would have built a second mirror.
- Supergirl: Yes. Where?
- Nxylgsptinz: The supply rooms.
- Nxylgsptinz: It will take both of us to get this mirror all the way back to the Anchor. Who's going to help your father? He can't even stand.
- Zor-El: Just leave me here.
- Supergirl: No. No! Absolutely not.
- Zor-El: This area isn't safe for anyone with Scar and the Phantoms roaming. Please, just take this mirror to the Anchor, activate the exit, and if it works, you can come back for me.
- Supergirl: I...
- Nxylgsptinz: He has a point, Kara. If we don't get him to the exit, his wounds will never heal.
- Supergirl: Father, I can't just leave you here.
- Zor-El: I'll barricade the door. I'll be safe.
- Supergirl: No. I-I won't...
- Zor-El: [in Kryptonian] Daughter.
- [switching back to English]
- Zor-El: Please.
- Supergirl: No one's called me that in decades.
- [reluctantly]
- Supergirl: We'll come back for you as soon as we can.
- Lena Luthor: You were right about the Crysalis. I'm sorry I fought you on it.
- Alex Danvers: I understand why you did. That's a decision I didn't wanna have to make.
- Lena Luthor: But you still made it. Listen, I am so grateful to be part of the team here in the Tower, but I don't think I belong.
- Alex Danvers: Why would you say that?
- Lena Luthor: Well, it's like you said. I need to stop atoning for the sins of the past. And I am determined to do good in the world, but... you and J'onn, Brainy, and Nia, I'm not like you. You're true heroes. I know how much your sister means to you, Alex, and yet today, you made the most painful sacrifice because it was the right thing to do, and... I don't think I could do that.
- Alex Danvers: Every moment I was running towards the Crysalis, I wanted to turn around. I didn't care if that Phantom took over the whole city or the whole world. I wanted nothing more than to drop everything and go after my sister. You know, I had to rely on my years of training as a soldier to help me push those feelings aside so that I could do what had to be done. You have a huge heart, Lena. And wanting to save Kara, that doesn't make you any less of a hero.
- Lena Luthor: Yeah, maybe not. But I still don't think like you.
- Alex Danvers: Neither does Brainy. Or J'onn or Nia. I mean, we all have different life experiences and perspectives and strengths. It's our willingness to hear each other out, that's what makes this a great team. And if it weren't for your brilliance in making that device, we all would have failed. You belong here, Lena. You always have and you always will. And besides, you are the only one with a decent taste in Scotch.
- Brainiac-5: There's been a precipitous drop in air temperature.
- Dreamer: [a portal opens and a Phantom emerges] The Prime Phantom, look at his size.
- Brainiac-5: He grows bigger with every life force captured.
- Dreamer: [Brainy fires the Prototrap] He's fighting it.
- Brainiac-5: We're gonna need a bigger gun.
- Dreamer: And that brings us to the end of our Tower tour.
- Lena Luthor: Thanks, Nia. First days always make me feel like an awkward schoolgirl, so thanks to you all for making me feel so welcome.
- J'onn J'onnz: I'd like to say on behalf of us all how great it is to have you with us in the trenches.
- Brainiac-5: Finally.
- Nia Nal: With your inhibitors off, you're feeling a lot of emotions right now.
- Brainiac-5: Lena advised me to embrace them.
- Nia Nal: Right now, you're not embracing them, you're eating them.
- Brainiac-5: Mmm.
- Nia Nal: I've been there. Kara and Alex, too.
- Brainiac-5: Their dumpling obsession.
- Nia Nal: A donut can't be there for you... but I'm here if you wanna talk.
- Brainiac-5: It's not a problem, Nia.
- Nia Nal: Okay.
- Brainiac-5: Well, I can stop comfort eating whenever I want.
- Supergirl: That Phantom almost made it through your portal with us. I can still feel him, like shards of ice coursing through my veins.
- Nxylgsptinz: No one said pocket-jumping through the Phantom Zone was for the faint of heart.
- J'onn J'onnz: Prime will have his progeny protecting his lair. We'll have to be careful around those talons.
- Lena Luthor: I may already have a fix for that. I couldn't wait to get started, so I stayed up all last night and made this.
- [taking a weapon out of its case]
- Lena Luthor: I merged a DEO protogun and L-Corp's portal energy.
- Dreamer: What is it?
- Lena Luthor: Well, I call it a Prototrap. It's designed to trap Prime Phantom and his progeny hands-free and transport them directly to containment.
- Brainiac-5: Just like in "Ghostbusters."
- Lena Luthor: Except that's a movie.
- Brainiac-5: It's the perfect movie.
- Lena Luthor: The Prototrap is real.
- Brainiac-5: Okay.
- Alex Danvers: Rescuing Supergirl and stopping the Phantom infection. I was afraid it was never gonna happen.
- Brainiac-5: You had a dream when we were at Noonan's, didn't you?
- Nia Nal: The same one. Kara and Alex in high school. And I don't know why I keep dreaming it, or what it means.
- [to break up the awkward silence, he opens his box of donuts to keep himself busy]
- Nia Nal: Are you okay? You've practically inhaled every donut in that box.
- Brainiac-5: Strawberry glaze with sprinkles is a rare delicacy.
- Dreamer: We need to find the Crysalis before it fully hardens.
- Brainiac-5: [a thought strikes him] Great Sprock. If we release the life forces from the Crysalis, M'gann will get her original soul back.
- Alex Danvers: But then she'll lose her sensing power to find Supergirl in the Phantom Zone.
- M'gann M'orzz: Then we have to find Supergirl before that happens.
- J'onn J'onnz: No. Absolutely not. First, we need to focus on defeating Prime and releasing the captured life forces.
- M'gann M'orzz: But, J'onn...
- J'onn J'onnz: If we don't act now, not only will National City be lost... but the infection will reach a point of no return. A global pandemic. If we only go after Kara, she'll come back to find another Phantom Zone right here on Earth.
- Alex Danvers: Okay, then we do both. We rescue Kara and we defeat Prime. Guys, we can do this. We can do anything if we just put our minds together. We always find a way.
- Lena Luthor: Absolutely. There's got to be another way to find Prime's lair.
- J'onn J'onnz: There is still a way, if we combine M'gann's sensing power with and Dreamer's ability to astral project.
- Lena Luthor: So I'll work on a way to try and copy M'gann's sensing power to track Supergirl. See, it's a win-win.
- J'onn J'onnz: You heard the lady. Let's go.
- M'gann M'orzz: I remember following this life force when I felt this tremendous force pushing at me. It was like a part of me was draining away, and then I saw I was turning into a progeny again.
- Brainiac-5: The double-soul dilemma. M'gann's original soul is with the others in the Prime Phantom's lair. When she flew too close to it, the piece that is her transfused soul sensed the original and they repelled each other like magnets.
- M'gann M'orzz: That's why I was turning again. I was close to having no soul in me.
- Brainiac-5: Based on the rate of Prime's accelerated growth and disembodiment, he'll soon reach full maturity.
- Lena Luthor: What happens after that?
- Brainiac-5: He'll become unstoppable, and it will be impossible to release the life forces held in his lair.
- M'gann M'orzz: That's what happened on Planet Dheron. A Phantom was released there, too.
- Brainiac-5: And just like Prime, he grew with every life force he took until he became completely disembodied. A small band of brave Dheronians found the Crysalis holding the captured life forces. But its shell had hardened when the Phantom reached full maturity. Even with their most powerful weapons, they were unable to breach it. The souls were locked in forever.
- Alex Danvers: [finding the Crysalis and the Phantom progeny protecting it] It's a Phantom Zone on Earth.
- Dreamer: [the progeny turn to look at them] No matter what happens, don't stop.
- [she uses her powers to conjure a protective barrier/tunnel for Alex to traverse; trying to fight two progeny off, she flashes to Midvale again]
- Dreamer: Sentinel, do it now!
- J'onn J'onnz: M'gann will use her sensing powers to find the highest concentration of life forces. That should be Prime Phantom's lair.
- Brainiac-5: Hopefully, in locating the lair, you'll be able to ascertain the condition of the Crysalis. In particular, any hardening of its outer shell.
- M'gann M'orzz: You ready?
- Dreamer: Let's do this.
- [taking M'gann's hand, she enters a dream state]
- Dreamer: All right, looking for clues.
- [she has another dream of Midvale]
- Dreamer: [waking up and shaking it off] Come on, they're counting on you.
- [finding the Crysalis and carefully touching it]
- Dreamer: Still translucent.
- [life-forces pass by and, seeing progeny preparing to attack, she wakes up with a gasp]
- J'onn J'onnz: Are you all right?
- Dreamer: It was horrible. I'm so cold.
- Brainiac-5: Are you okay?
- Dreamer: Midvale. I saw Midvale again.
- M'gann M'orzz: So, is that where the lair is?
- Dreamer: I don't think so. I'm sorry. But there's something else. The Crysalis, it's turning solid. We're running out of time.
- Lena Luthor: It took some work, but it's finished. With this, we will be able to find Kara in the Phantom Zone. We'll finally be able to bring her home.
- Alex Danvers: Not today. Look, in less than an hour, the Crysalis will harden over, trapping all of those souls inside of it forever. Plus, more people are getting infected by Phantoms every minute. It's spreading like a plague. Now, I know how hard you worked on making a device that can track Kara. But now we need to recalibrate it so that we can find the Crysalis instead.
- Lena Luthor: But if we recalibrate it, we'll overwrite Kara's DNA. We'll lose our only chance to save her.
- Alex Danvers: We'll find another way. There's always another way. She taught us that.
- Lena Luthor: How can you choose to save anyone else over your own sister?
- Alex Danvers: Because if I don't, countless lives will be lost. Kara would always choose saving others; that's just who she is. And how do you think she would feel if we rescued her and she found out that we let thousands, maybe hundreds of thousands of people die just so we could have her back? Supergirl relies on... on those that she loves to follow her example. So please don't make this any harder than it already is. Give me the device.
- Lena Luthor: Alex, I hear what you're saying, but... I have to bring Kara back. You see, it's my fault. It was my brother who sent her to the Phantom Zone, it was my experiments that empowered him. It was my war with Supergirl that started all of this. So if this is my only chance to make it right, then I have to do it.
- Alex Danvers: Okay, Lena, listen to me. Nobody blames you for this. Kara doesn't blame you for this. You two already forgave each other for everything that happened in the past, so it's time for you to forgive yourself. And all that really matters is that you do the right thing today. So please give me the tracking device.
- [using her Martian wristband to summon it]
- Alex Danvers: I'm sorry, but I can't take no for an answer.
- Supergirl: [turning the exit mirror on and seeing the Fortress of Solitude] It's home.
- Nxylgsptinz: It's beautiful.
- Supergirl: Let's go find my father.
- Nxylgsptinz: Kara, we can't. It's too dangerous.
- Supergirl: What? No.
- Nxylgsptinz: Kara, honey. I know you believe the best in people. But don't you understand? Your father is beyond saving. He's been holding you back ever since you got here. Even today, you saw just how quickly he was ready to give up.
- Supergirl: But he pushed through that. He... he got us here.
- Nxylgsptinz: He also stuck you in a pod when you were just a child and sent you to a foreign planet alone. He banished you, Kara, just like my father banished me.
- Supergirl: I'm sorry about what your dad did to you. Truly, I am. But I'm going back for him, whether you're coming with me or not.
- Nxylgsptinz: I should have just slit his throat when I had the chance. I was going to. I was this close.
- [holding her thumb and index finger about an inch apart]
- Nxylgsptinz: Instead, I conjured myself up as Scar and I knocked him out instead. I let him live for you.
- Supergirl: You're the one who attacked him?
- Nxylgsptinz: Mm-hmm.
- Supergirl: [realizing] You wanted me to activate the exit because it wouldn't activate for you.
- Nxylgsptinz: Oh! Don't act so shocked. You wanted to be free of him, just like I want to be free of my father. You were just too weak to get rid of him yourself.
- Alex Danvers: If only there was a way to use Prime to make a new tracking device. I mean, i-if he was part-human like the progeny.
- J'onn J'onnz: I tried searching his mind, trying to convince him to look for Kara, but all I could sense was thirst and misery. He has no humanity, only instinct.
- Lena Luthor: [getting an idea] Instinct. The... t-the Phantom, he-he tracks by instinct. He's a bloodhound.
- Brainiac-5: If we can get our hands on more of Kara's DNA...
- Lena Luthor: Then he'll track her by instinct.
- Alex Danvers: It's a good idea, but the hologram crystal is broken. How are we gonna get more of Kara's DNA?
- M'gann M'orzz: We can collect DNA from a Kryptonian after a solar flare.
- Lena Luthor: Or kryptonite poisoning.
- J'onn J'onnz: Alex, can you remember all the times Kara blew her powers out?
- Alex Danvers: It's only happened a handful of times. Uh, uh... once was in a fight with Red Tornado, and then another was all the way back in high school.
- Brainiac-5: Back in Midvale?
- Alex Danvers: Y-Yeah.
- Brainiac-5: Nia.
- Nia Nal: Cassandra, this is what my dreams have been about. If we want to bring Kara home, we have to go back in time... to Midvale High. I just hope we're not too late.
- J'onn J'onnz: The Prime Phantom will never hurt you, or anybody else, ever again. I'm glad you're okay.
- M'gann M'orzz: Me? I almost lost you today, too.
- J'onn J'onnz: Well, now you know how it feels.
- Brainiac-5: In spite of everything we went through today, we're still back at square one. No closer to getting Supergirl back. And no matter how many donuts I eat, this hopeless feeling just won't go away.
- Nia Nal: I feel it, too. I've had more dreams about Midvale.
- Brainiac-5: What do you think they mean?
- Nia Nal: I don't know. I'm scared, Brainy. These dream flashes of Midvale, Kara and Alex in high school, they keep happening, confusing me, and I don't know how to stop them or interpret them. I just wish my mom was here.
- Brainiac-5: Look, I'm sorry you don't have your mom.
- [taking her hand]
- Brainiac-5: But you have me.
- Nia Nal: We have each other.
- J'onn J'onnz: [searching for the Phantom's lair and coming to a crossroads] Which way?
- Brainiac-5: [instinctively raising the Prototrap as a Phantom appears] This way looks promising.
- Supergirl: Hurting an innocent man doesn't make you powerful, Nyxly.
- Nxylgsptinz: [chuckling] Oh, I know what makes me powerful. And the power that I have here is only a shadow of what I'll have once I get to Earth. Hmm. I was going to go straight home to the Fifth Dimension to punish everyone who didn't stand by me. But you activated the exit. In order for me to get to my home, I'll have to go through yours. And you know what? I think I'm gonna have a little fun while I'm there.
- Supergirl: Over my dead body.
- Nxylgsptinz: [throwing Kara into a computer panel] You know, this is fun. But it gets old after a while.
- Supergirl: [hearing the announcement of the self-destruct's activation] The impact must have activated the self-destruct. We have to get out of here.
- Nxylgsptinz: The only way I'm leaving here is through that exit.
- Supergirl: [picking up a spiked club] I can't let you do that.
- Nxylgsptinz: [laughing] Go ahead. Take your best shot. You and I both know that can't hurt me.
- Supergirl: [glancing at the self-destruct sequence and then the exit] I know.
- [she smashes the mirror]
- Brainiac-5: Based on what Dreamer just witnessed, I've calculated that the Crysalis will become impenetrable, trapping the life forces in one hour's time.
- J'onn J'onnz: Our only hope now is to find that Crysalis before that happens. If we release all of the life forces back to their rightful owners, we'll cure everyone at once and disempower the Prime Phantom.
- Dreamer: Well, we can't do that until we find the Crysalis.
- M'gann M'orzz: I can lead us to it.
- J'onn J'onnz: No. No, M'gann. If you get too close, you'll transform. I'm not gonna lose you again.
- M'gann M'orzz: We have no other choice.
- Alex Danvers: Actually, we do.
