Morning hinted at this, and Happy says it's an incorrect assumption. Then I supported Morning, and then I agreed with Happy, because there's protection and +yesterday's block on KOShi.

If Morning is a Mafia member, then killing Medzh would be very fitting, because no one would suspect him (because of the previous Mafia).

At least it's clear that Morning is not a Guard, not a Watcher, not an Informant, not a Barbarian, not a Pirate (if he killed Hermit), not a King... and it's quite possible that he's not a Sorceress either.

I think he should be blocked at night and his status checked to be sure.
