That's an excellent point. I still don't think it's autism (Thought that is an autistic trait), I think it's more that "this is weird, this is not how I was brought up but it seems to make her happy so I'll go with it."
I don’t think Perrin is DID, because the wolves are not inside his head-they are flesh and bone in the world and they’re speaking to him-it’s a different form of communication, but hey exist outside of him.
Galad I can go with, although he was very aware of how women looked at him and the fact that they were attracted to him, and it's my experience that this isn't the case in autism (speaking VERY GENERALLY). Perrin...nah.
