They're mobsters. It's funny that people tend to forget this and almost expect these guys to talk about the latest trends in gardening or something. Although, to me it's completely out of character for Sonny to advocate going after an enemy's kid. That's never to my knowledge been something he's ever looked to do. And Sonny never said he'd go to Belize with her, why are they now saying he did? This show....wow!
See, I'm ok with this in theory. Mobsters are suppose to do mobster things. What I hate is the show trying to present the mobsters as the guys we should be rooting for. Or treating them like noble, romantic heroes. Or letting them skate on all the murder and mayhem they've done. No doubt Sidwell will pay for his crimes in some way. But Sonny? Nah, he can gun down a man in cold blood and it's just swept under the rug, never to be addressed again.
