Haven't read most of the day so I'm sure I'm just repeating what's been said but
Well, we know that Cthulhu visited fitz because he said he was going to. Probably safe to assume Ponystar visited REM. Varian is a bit trickier. I was hoping his last few posts would have some sort of hint in it as to who he inspected, but at the very least there's nothing I can see. Probably inspected Ika? If he inspected Ika, scum HAS to be fitz and REM because ika can't have armed as scum - before ending night, the mod said he was prodding ika, so ika can't have sent in an action. Kind of a crappy way to eliminate someone as scum, but it would be stupid to ignore it. The only other real possibility is that Varian inspected either fitz or REM and that scum got a 2-for-1 special.
This was the last thing Varian said about REM, unless you include
this. Both of those indicate that Varian wasn't particularly suspicious of REM. The latter also indicates that Varian was probably not particularly suspicious of fitz (Varian never gave an opinion specifically on fitz). So yeah, unless, Ponystar visited someone he wasn't supposed to, the most likely scenario is that Varian did cop ika and got killed, while fitz and REM both armed and venged their visitors.
But I want to actually read what's been said today before voting, in case I'm missing something. Will read soon-ish.
