I know that they were confusing him and Pusy with each other when the revelation came but a lot of things point to him being a rat
Pro's for being a rat
-Asking about stuff that's already been covered
-Seemingly trying to get Tony to say something incriminating
-The way he said 'Oh god' when he was called a rat, although it could easily be fear of him impending doom
Personally I would've liked to have seen more of Jimmy rather than Carlo Gervasi as a character
I think the difference between Altieri & Bumpansero was length of time being an informer. Jimmy was probably turned at the raid we see on the club, whereas BP was flipped in '95. When Jimmy comes to Tony's house, he was obviously wearing a wire. Same with the meeting Jimmy called for in the beginning of the next episode.
