I'm having slight doubts on Comp primarily due to HK dying on night 1 and the tendency for comp to bring his AoD banter everywhere he goes, though it is far from being a good reason to lynch him.
That aside, however, no one in particular stands out much. I was slightly suspicious of pink on the first day, but now putting things into perspective I doubt her involvement in the mafia.
Here's my thought process on the kill last night so far: The fact that Ender was killed and that the last few people he pointed out for being suspicious are me and comp - now that I do think about it, the paragraph I had above seems like an attempt at distraction (I assure you it's not) - is particularly interesting, in particular to comp and I. Mafia probably did not know that Ender was cop before his role was revealed, and they killed him probably due to him being a strong player - but this raises the question of whether the mafia killed ender in an attempt to distract town from them by pointing fingers at someone else, or as an attempt to eliminate the person who suspected them most (or if they even considered his suspects at all). The former one is a weak argument since the mafia probably did not know Ender's role before hand and they would not know for certain that the rest of town would take whoever his suspects were into consideration, which leaves the latter. This is the part that's really confusing so far because even if I have doubts on Comp I still don't think the chances of him being mafia are particularly higher than anyone else.
I'll recalculate the setup probabilities again tomorrow if no one else is going to do it - it involves a tiny bit of code, but this time we're doubly sure that there's no second killer and we know that there's at least one villager and at least one cop. Hopefully when I calculate the weighted sums for each role something meaningful could come up.
