Why not? He's alone and there is a seperate group of evil doers, a new Angus. It is entirely possible, though I doubt that is the case.
It is more likely Angus is indeed part of the mafia who are a group that he has "hired" or acquired in some way.
I'd like to hear from Sprout and other people who haven't spoken much, I saw Marcmillian looking earlier as well.
