It could be unique to his world or species too. And the breathing... He had that device on and he seemed to have a hard time with it after he had the little fire display. Might be he had some kind of injury. Might not be related though.
[She takes a breath, thinking it over.]
He's unstable and mostly well intentioned and if we turn him away then he's still here. Still with members of the team and people less equipped to face him. If we take him in, give him purpose, keep an eye on him... It might be the better situation.
I'll move Picard to another team. [He'd be a good leader for one once his current problems are sorted out. If they get sorted out. She was never entirely comfortable having him in sector 6 even if his diplomatic skills and experience with various lifeforms was a good fit. Even for a human combatant he was...not at the top. A little older. Certainly fit, but more used to a weapon which wasn't something they came by easily.] We can try him on sector 6 team and be careful about what information we give him. [She voices it like a decision, but also looks to the two of them. It's a good time to tell her she's crazy if they think it.]
