The Battle School Mafia discussed this very thing while they waited for their next class to begin, seemingly joining in with the camaraderie that the rest of their army was trying to portray.
'Everything is ok.'
'Yeah, the teachers will figure it out and put a stop to it.'
If the logic was correct and there were 2 mafia left last round, then this certainly leads me to believe that Domo was a townie since we've still got a discussion going on.
Of course it could mean that the logic was incorrect. Not sure. That was just the first thing that grabbed me though (and the repetition of 2 last time round did seem like a big clue at the time).
