The Mafia phase coincided with Revan's (re-read the newspaper if you don't remember). His own Mafia killed him. What is the deep philosophical meaning?
1. Create the illusion that they were redirected.
2. Create the illusion that the Mafia are new players and don't understand what they are doing.
3. Block the doctor so that he cannot heal himself.
4. Simply use the block to confuse the peaceful players - if you remember Naver Leengard and the city blocker. That is, if there were a second block, the city would decide that the Mafia were not blocking their victim, but someone else who would be blocked by a peaceful blocker. And who knows, he could end up being a Mafia member, thereby creating a peaceful image for him. Because it's not logical for the Mafia to block their own member... )
