Jade keeping it together is a measurement of how much time he has left. The moment she breaks down completely and can't even sum up herself any longer, that's when he has to make an important decision-- take her away from here, find somewhere safe, and pray to God he can break Hypatia's grip on her before either of them die. He just hopes that everything he's been doing over the past few years amounts to something, that he won't ultimately fail her.

He heads over to sit next to her. "Same as ever. Manage t'get any sleep?"

Probably not. It's hard to get any rest with an alien AI in your head.
