I agree with all of those, especially Doc. I found out that he was the Cop on Night 1, and we went off from there investigating Capt. Redblade and Cutlass Iz respectively. I must say that we were very lucky that Kartoffel decided to protect Doc on Night 1, because if not for that the Town would have most likely lost. I was already in discussions with Kartoffel and I suspected him of being the Doctor, however, he made it pretty well known that he didn't trust me at all. I don't blame him, if I was the Doctor, and someone was fishing for information from me, I would be pretty suspicious of him, too.
