Kira needs only hear Credence's name from Graves' lips to know what has happened: he'd been aware of something within Credence from the first they met, and had it recently given name by Tina. There are small, selfish reactions as his face and posture tighten, he stands to his full height in the crowd and tunes out of what's actually being said.

He told Tina Credence was weaker, they're all weaker, this shouldn't--

He told Credence he wasn't in control.

Swallowing, he stops looking for his friend in the crowd. Stops looking for anyone. Maybe he should care more, that there are injured among them, that even if he isn't any kind of doctor, there are jobs he can do with his unharmed limbs to help. It doesn't matter. None of those people are Credence, and after Casey, after Ren and Ty, Kira isn't letting loss come in fours.

"Excuse me," he says stiffly, nudging his way through the people behind him to find the door. Medicine might not be his thing, but if there is any job he is remotely qualified for in his stupid life, it's talking to Credence Barebone.

[Establishing Kira's presence and his reaction; tags welcome but he will not linger, he's going after his friend.]
