He sounds like he would be a great fit with the group we have so far. It would be the handlers, like Cassidy here, who primarily have access to his records, and they aren't supposed to divulge that sort of information to non-handlers, though accidents happen and people have their ways of learning.
roguecharm might get along with him. He's not so much sarcastic as playful, but I think they would get along well enough.
