"You think Praziquantel's claim doesn't make sense? So what?"
You began your accusations against Artsapat and rana after they voted for Praz. That means either Praz is guilty and Artsapat and ranagrande are clean or Praz is scum and rana and Artsa are innocent. (I know this is kinda simplistic with other possible factions and scum voting for each other to avoid suspicion but you get the basic idea.)
Thus: In your accusations of Artsapat and ranagrande in turn it seemed to me you were assuming Praz is innocent which is not an assumption I am comfortable making.
Cancer never fights fair. Rest in peace Mrs. Cohen, you will be missed.
