Hmmm I think something is up with Carlo as well
1. Turning state witness just cause your son gets pinched with a little X? I don't buy it, would Carlo give up his whole lifestyle to go into witness protection just over some x? Even Meadow senses there's something wrong when they say Jackie Jr. died because of a X-deal gone wrong. We don't belive you Carlo.
2. The disguisted face on Carlo as Tony says he won't visit Syl at the hospital. This is followed directly by the scene where Butchie talks to Phil on the phone. Is that a coincidence or is this a hint that just like Butchie & co. Carlo, Benny and the rest of the bunch felt the same way about their boss at that point?
Btw, Carlo was the Don of a New Jersey mob familiy in Running Scared
