I think it could end with an uprising in Tony's faction. Perhaps whomever takes control (Paulie? Silvio?) gets Christopher to whack Tony. I dunno.

Olivant, I didn't think that the cops knew about who whacked Jackie Aprile (unless that Capo, I forget who he is, the guy who had flipped told them?)? So why would it make any sense for him to tell the women?

I don't think they'd want Tony to talk, but it would send home a message that even the most hardcore gangster is really a coward at heart.
