I haven't been paying attention to the show really, by that I mean not watching the past few episodes, but I have to know. What is the importance of Bellamy and Clarke signing each other's names? What is it for? What does it mean?
Well, anon, I’m so goddamn pleased you asked.
Effectively, 403 starts us out with Raven putting pressure on Clarke to make a final list the 100 Skaikru who get to ride out the end of the world back inside Alpha Station, meaning Clarke has to make a call to sentence 400 of their people to death.
Obviously, she’s feeling a little resistant about having to do this, but one thing she won’t tolerate is Bellamy Blake saying he won’t be on the list (I think it’s probably the most emphatic we’ve seen her in a while, tbh. Anyway, push comes to shove and Clarke makes a deal with Raven that she’ll make the list by the end of the day if a potential lead on another bunker where more people could survive doesn’t pan out.
Shockingly, because this show is this show, turns out the bunker isn’t sealable, so now Clarke has to face her list.
Naturally, Bellamy’s keeping her company while she does it, and they’ve made it down to the last two spaces available when the audience joins them, and Bellamy’s drifted off, maybe in the span of a few second prior, maybe Clarke’s let him sleep for a while IDK BUT I LOVE IT (shout out to those kabby parallels).
Anyway, Clarke looks over at the sleeping Bellamy and we get just the slightest relief in her face before she writes down his name as number 99. With one spot left, Clarke can’t bring herself to write down her own name because, you know, she really doesn’t think she deserves to survive. Obviously, that’s the kind of thing that is hard to wrestle with, and Clarke lets herself have a cry that she’s been way overdue for, honestly, since 216.
Naturally, Bellamy wakes up, and in seeing his name on the list doesn’t fight Clarke on it, just does that lovely soft husk he uses when he talks to her, and tells her that if he’s on that list, then she is too. Bellamy insists she write her own name down, and when she can’t, he takes the pen and writes her name for her.
Basically, bellarke just wrote each other into life, and as a lot of really smart other people pointed out, it’s Bellamy and Clarke going beyond needing each other as leaders, moving to the point where they can’t imagine surviving without the other.
