Ok so I've been thinking about the various possible team combinations and this is what I came up with. I'm removing Yellow from consideration here for simplicity's sake because he's pretty much obvious town.
Orange/Pink:
lmao
Pink/Blue:
Initially, I wrote off the theory that Pink was bussing Blue due to the fact that Pink's basically been on Blue's nuts the entire game. However, when I reread, I notice that while Pink parks his vote on Blue, he doesn't really pursue it with as strong a conviction as I normally see from tunneling townies. Furthermore, Blue doesn't really do much to react to the push until now.
Orange/Blue:
This team combination would explain why Yellow is still alive. Yellow's been on Pink since D2 and an Orange/Blue team would want to take advantage of Yellow's FoS in lylo by keeping him alive to misvote.
Looking at the players individually, Blue's ISO is actually the least impressive. He mostly just sheeps others' reasoning and flies under the radar throughout most of the game. While I liked his reaction to being pressured after his "hammer," he's basically disappeared since then. But most importantly, he is the only player I can see on a scum team with anyone here. Hell, even if we were to imagine a world where Yellow is scum,
Blue is the only player that could be his partner.
Furthermore, given the choice between Pink and Orange, I'm having a hard time deciding. Orange does make some good points about Pink's scumhunting in this game but I'm not so sure I can trust him given the weakness of Orange's predecessor. The first Orange basically spent the entire D2 with his vote parked on Pink and doing basically nothing to advance it, maybe expecting an easy ML. So given Blue's extremely lackluster ISO and partner interactions, I'm going to have to swallow a major bullet and vote Blue here.
God, I kind of regret giving him a free pass due to his noobishness but now I actually see it was mostly just a smokescreen to cover his intentions.
VOTE: Blue Mask
