Tony seemed to already be in a hell of his own making by the end of "The Blue Comet."
There are rumors, which Sopranos creator David Chase denies, that the finale will be left open-ended enough for a full-length feature film to be made.
Hey, maybe Tony will introduce Phil's gang to his little friend, go crazy and in his bloodlust, also go and try to kill Dr. Melfi haha and then get killed himself...by Dr. Melfi hehe. Not likely, but I thought it was good for a laugh. More likely is that he will appeal to the FBI agent for assistance or possibly become a witness.
The last one was fairly telegraphed. The amount of camera time directly on Bobby in the scene in the hobby store made no sense unless he was about to get whacked, so you knew it was coming; and hence the title of the ep "The Blue Comet" (for the toy train).
Sil does a dirty deed in the beginning (to have us lose a bit of sympathy) and then gets shot multiple times though the car. I suppose Silvio in a coma or something now.
Leotardo and company didn't put a hit out on Paulie because they figure they can co-opt him after...I'm anxious to see how that part is gonna play out.
