Mafia 70. Jabalah

My version is this: the Mafia decided not to reveal themselves, which is why they didn't vote for Ment. Then I appeared and was the first to cast a vote against the Serial Killer, which Sesam promptly used to her advantage, accusing me of being Mafia (saying that only Mafia would benefit from voting out the Serial Killer) and thus supposedly clearing herself. That night, Sesam and her teammates decided to block the first vote, in order to further clear her name. Thus, the decision was: execute Ment, execute Sesam.
