[ Still unsure, but Kitty does have a point. Better have him on the team where they can keep an eye on him than out there, unsupervised. It wouldn't be the first Defence Force member they use that tactic on either. ]
Okay... you have a point. Even if he's not a good fit on the Force, this would give us more time to observe him. If he turns out to be a threat more than an asset, we need to know how to contain him.
