Penguin and I got each other clean, which gives:
Penguin cleaned MC and myself, and is either Sane or Naive, or Mafia
I cleaned Celever and Penguin, and am thus Naive or Sane, or Mafia
Twin found himself and Celever mafia, and is thus Insane or Paranoid, or Mafia
More Cowbell found Celever mafia, and died, and it thus Insane, Sane, or Paranoid
Celever was hooked and then no results known yet.
Option:
If I am mafia, then Penguin is Naive. That makes Twin and More Cowbell Insane or Paranoid, and Celever Sane. MC can't be sane because he got celever mafia. No contradictions yet.
If Penguin is mafia, then I am Naive, Twin and MC are Paranoid or Insane, and Celever is Sane. No contradictions
If Celever is mafia, then Twin is Paranoid, More Cowbell is Sane, which leaves me as Naive, BUT Penguin is either Naive or Sane. Insane is not taken. Contradiction. Celever is clean 100%.
If Twin is mafia, then Penguin and I have sane and naive, MC and celever are paranoid or insane. No contradictions.
In short, Celever dies tonight, sorry. We puzzled it out while you were out.
I lack the data to decide between Penguin and Twin.
