I thought Tony said he would assume "the guy's debt". In exchange for the 6K tab at Vesuvio's, Tony takes over the hassle of collection.
Tony will find out about the heroin and rough Chris up but he won't whack him. Tony's right about the rest of the capos being too old.

When the thing at the beginning said there'd be nudity, I got worried when AJ was making out with the girl and planning to get it on with her. I didn't want to see a HS girl naked. Even if she was 18, it's still creepy.

Artie was different than Scatino. Scatino approached Tony and begged to get in the game. Tony knew he was a degenerate gambler and warned him that this was the big boys. He persisted. Tony figured that David would ruin his life one way or the other so he might as well make money off of it.

With Artie, Tony pushed him so he'd have been easier on him. Also since it was a case where someone owed Artie the money, it would be easy for Tony to assume the debt. With Scatino, he owed the money to Tony. If someone owed Scatino, Tony may have let him off the hook.

Are the Bucco's divorced? Charmagne looked about 10 years older. She's always reminded me of Appolonia in GFI. I had to check to see if it was the same girl.
