The kiss hurts, but the pain is different. It's sweet, it's a clear reminder of who he is and who Isaac is and that this is real, that they're together again, that for the first time in a long time, he can know for certain things will be okay.

Home. They're going home.

He's not even sure he remembers what it looks like.

Jack doesn't notice the bodies, he's too busy concentrating on the fact that he's alive, he's going to stay alive, and Isaac's here, and they're going home and he doesn't know if he can even process it all, it's too much for him to handle.

Shit he feels like he's going to pass out.
