Both FT and rana seem equally believable and unbelievable but if I had to choose who to believe it would be FT. While I do find the no-lynch victory thing strange, he was the first to claim it. The others might be bandwagoners, or scum trying to encourage no-lynches to get to the night phase, but rana's survivor claim and initial doubt about FT's role seems especially suspicious.
I am ready to vote for rana, but I could be easily swayed to FT (or Taiga I guess.)
