Piona is doing a good job; for the reasons mentioned earlier, she ruined Inar's setup and the redirection from the Mafia.
Makka was Aolus. As far as I'm concerned, Albei would be described differently, and he fits the role of a member of the mercenary organization Chinax and, probably, his long-term subordinate better than the others.
I don't really like Tox because, on the second night, when it was already clear that Nebok was the one killing in the first night, he was still trying to frame Neira as Albei, even though Alm is simply incapable of killing her. Initially, I thought he was Albei himself, pretending to be a dead person, without noticing the attempts to impersonate Shendet. Moreover, Shendet is not a role that benefits from revealing himself in the game, considering that the Negatives gain more from it. But this is still Tox, and he likes to go out of his way to act like a Negative, even when playing for the Town. And we know for sure that he (as well as Ment and Yashur) is not the Serial Killer.

Ah, and Crabbi can't be the Serial Killer either; I completely forgot about him.

While Tox is a shady type who can easily justify why the Mafia doesn't target him (they don't want to provoke Shendet!) and scare off the Town (so that the kill doesn't go to waste), while at the same time distracting checkers or blockers (whom Lo can ignore), I'm still not sure if this is just a result of his strange playstyle. I don't remember Tox particularly guessing clues, but I don't remember how often he does it in general. In any case, the Mafia (especially the one who can't be executed) has a much lower priority than Inar (who is strong on his own) or Necoran (who can go wild if something happens to Theodore). Possible candidates for the Serial Killer, based on block-isolation, are:
MedjersoN_HP
Nefela
Morning
Tiel
Arandor
Heroist
MasteR
Me
Tox and Ment are ruled out due to the previously mentioned isolations with blocks. Crabbi is ruled out because he fell victim to black magic, which Shendet could not steal and use on Necoran himself, and to which Inar is immune. And this is without mentioning the fact that Inar was most likely in isolation and would not have appeared in the newspaper. For the same reason, I cannot be Inar either. Unfortunately, I cannot prove by analyzing the newspaper that I cannot be Necoran.
