I obviously enjoy this episode a lot, it's one of my favorites. But I also understand why you wouldn't. The most scary part of this season has been reality from the very start. The reality of growing up, and the reality of getting lost on the way. The reality of being on a path, but not knowing if you really like where it's going. It's no longer about the horrors of growing up, but about *being* grown up and still not having all the answers.
As far as this theme is concerned, "Normal again" ist something like the first Season Finale. And while you normally watch TV to *forget* about all the existential fears and let go of that boring dystopia out there, here it's not only lurking behind every corner, it's breaking through the wall and overwhelms everything. This won't make you happy. This won't make you comfortable. Nothing to ship here, nothing to swoon over.
But it's so good. It's woven perfectly into the rest of the plot, and everyone was obviously having a blast taking part in it. The growth on the technical side is one of the things that are worth bingewatching this series on it's own, just as much as watching the characters and there respective actors grow. It shows once more that the writers can do so much more if you let them, and they will go back to quirky and witty soon enough. But the funny and light parts of the story couldn't shine as bright as they do without episodes like this one, just like "Normal again" thrives because it's so absolutely not normal.
This is an episode that I really treasure more and more every time. But I understand how it can really tire you out.
