It's going to have to be "Raymond Curto"
The guy has been a rat for forever now. Its only a matter of time until he is caught and disappeared. I would speculate that with the New York family going down at the end of last season, Tony will put some effort into getting a mole at the f.b.i. or some other tactic to find out if he has any rats in his house. Once that is done, Raymond is gone.
