Yeah I watched this episode again yesterday.
Still trying to crack this nut even though there is no real way of knowing what happens unless one day Chase tells us.
The only this is that damn guy in the members only jacket that makes me un-sure about Tony's survival and he's a bit shifty looking.

Speaking of members only jackets, before Vito pulls up Eugene about wearing one I had never really heard of them? Is it just a common styled jacket worn by mafioso in the 80's & 90's? What's the significance?

I think Capo de la Cosa Nostra has great points. Where's the point in killing Tony after Phill already getting whacked and a truce made with Butch. I mean there's still motive, an eye for an eye I guess or an order from Phill that was never cancelled by Butch but...
I've got to say I think they have dinner and walk away. Eventually Tony goes to trial.
