The eating the orange at breakfast (think Godfather). The meeting with Uncle Junior that was a farewell. And then the last line at dinner to remember the good times.
Also several episodes ago talking about getting wacked, that you never see it, just goes black.
And the Members Only Guy went into the bathroom, like Michael Corleone, before coming out and shooting Tony, so perhaps the gun was planted in the toilet, just as it was in The Godfather.
Wow. I never noticed that. Could it be connected to this scene the last time that same song was used in the show? A hint as to what was going to happen at the end?
