Morgan responds with a slightly nervous, noncommittal sort of noise. He's not about to debate whether or not someone else using his body to do something means that he's done that thing himself, not with someone who has yet to, and hopefully never will, witness the phenomenon in question, anyway. For now it's simple enough to just excuse the worry with "I'm Kindred. Things happen. Hopefully I can just take your word for it on your reaction time."
He doesn't really comment on Jacob's idea of socializing or even on the fact that most people who actually want to socialize with him, Morgan, tend to be vaguely suicidal. It's sort of getting into his head now exactly which thoughts one should and should not voice at which times. He does, however, manage to put a joking tone into his voice as he says, "You know, socializing tends to mean actually going places. I think I've been doing pretty well for myself as a hermit."
