But why in the world would Paulie flip?
They're always talking about how lonely Paulie is... maybe Ade is giving him some "extra attention".

Of course, the NJ family has always been tought of by the other familes as almost a pseudo-family. As Carmine referred to them, a glorified crew. That kind of disrespect breeds contempt which Phil has plenty of.
