"We have to do something," Bellamy says, even though they already have multiple times, even though he knows the one way this works out is the last thing he wants to put Clarke through even in a dream. There has to be some way to fix it all, or to at least leave the mountain with most of their people, scattered as they are.

But there's no way he can think of to save them all. They've tried.

"We have to," he repeats, and that's when dim emergency lights finally flicker on, running off whatever backup of a backup generator is out there. It paints their skin sickly green and the monitors light up again, each screen familiar. Emerson is gone, finally leaving them a way out, but they're still separated, still levels away from everyone else.

Movement on one screen catches his eye almost immediately; all Bellamy sees is Octavia fighting back, but she can't be doing that, it's just her against all those people, just her and Maya and he barely watches her go down before he's headed for the door.

Not Octavia. Not while Bellamy still has breath left in his lungs.
