No real signs that I picked up on at the time. I talked with his ex-fiancee when I found out, and she said it manifested itself into a paranoid schizophrenia where he was worried about being listened in on. One time I emailed him and I asked him "how are you doing, enquiring minds want to know?" His response was "Who are these enquiring minds that you are asking on behalf of?" I thought he was joking at the time, but I guess that was a sign.
