Weird KK Hand

This hand was kind of strange. I called on the flop in case MP3 was betting a draw vs. the pot size. I think this wasn't a reverse implied odds situation because I would easily fold on the turn if a flush card came down. I think the flop may be the most controversial street. The rest looks fine to me.
