thanx for remindin me about Eugine ..and now i added him

but as for jimmy ive seen season one and he is a rat !

Tony grew suspicious of Jimmy shortly after he was busted. He thought he was released a little too promptly after his arrest. Also, Jimmy began asking Tony, among others, for repeated details of their criminal dealings. Although it was never officially confirmed that Jimmy was a "rat" on the show, his odd behavior was enough for Tony and others to think he was wearing a wire. As such, Uncle Junior sanctioned a hit on Jimmy and said he wanted a message to be sent. Christopher lured Jimmy to a hotel room with a beautiful Russian girl as bait. Once Jimmy was seated in the room, Silvio came in and put a gun to the back of his head. Jimmy realized what was about to happen and went for a gun in his ankle holster but was too late. Christopher and Silvio taunt him by saying he should call for help down his microphone (a wire) - at which point Silvio shot him in the back of his head. Given that he didn't deny being a rat when he was at gun point, it is likely that Jimmy was an informant. As for the message, Jimmy's body was found in an alley with a rat stuffed in his mouth. Christopher even went so far as to call in a bomb threat to Jimmy's wake, to which Dante replied, "See now, that's over the top."
