Adam Strange: Seg, I know how this sounds, but please. This is a key moment in history. Things need to unfold the way that they originally did. Okay, any changes could set off history in some new and crazy way, and something huge, like stopping Brainiac, that could ruin everything.
Seg-El: By everything, you mean my grandson. Your obsession. Tell me, how is it that my world goes extinct, but he ends up on yours?
Adam Strange: He was sent off just before this planet explodes. That's why he's called the Last Son of Krypton. I don't have all the answers here. I admit it. I guess if... if Brainiac doesn't take Kandor, if Krypton doesn't explode, then anything can happen. And maybe Kal-El will exist. Maybe he won't. But what I do know is that is a risk we cannot afford to take.
General Zod: One might argue that millions of lives on Krypton are more important than one immature survivor on Earth.
Adam Strange: And one might argue how many times Superman saves the universe, if you want to count numbers.
Seg-El: Forget the numbers! I care about my world. My friends. What's the point of any of it? Or making the world a better place? Of having children? Of protecting our loved ones? If it all just ends in fire and death? Everything that we are. Everything we've built. You're asking me to sacrifice all of it. For an idea. An abstraction. A future if.
