Okay, I believe Reborn is a good choice tbh. He protected Fuji quite early on, he protected Rhea quite early on. He said it depends on the context, but I'm not exactly sure what he meant by that.
Interestingly in one of his posts, he said something like Beta, Midnight, Rhea are all players that are hard to read.
I don't remember why he said that post exactly, but him bringing up midnight at that time is very suspicious now seeing midnight's flip.
