I just got to THE TWIST in P5 and man...it's barely even a twist at all, if some nerds hadn't been screaming about it on Twitter I wouldn't have even thought of it as one. The game tells you at the start there's a traitor and it makes literally no sense that it could be anyone else and that dude was being sketch the entire time.

I guess they try to make Sae and Makoto out to be slightly suspicious but even that's an obvious red herring.
