Is he asked how he knows the demons or the keepers? pretend to be swayed how and why?
Well...Kyo isn't giving me a straight answer either, actually, but I think the idea was to challenge the psychiatrist and see if he can actually produce a convincing enough argument to win him over. And what he means by saying he doesn't know the truth is that he hasn't known either Katherin or the doctor for very long and could probably still be easily influenced. After all, he hasn't exactly spoken to either of their demons directly, so they could be telling their hosts to tell him anything.
...I might just change it, though. I feel like there are still flaws with this logic.
