For those who are unsure of what happened at the end and for this reason feel the episode was a disappoint.....Tony got whacked.....thats what happened when the screen went black.....If you remember Tony and Bobby's convo about what it'd be like to get clipped, they said i bet you don't even realize it happened, it just happens.....Since the show is from Tony's viewpoint, when he gets clipped, everything just goes black, and there is nothing more. It was a genius way to end the show in my opinion, very creative and ensured that only people who had followed all the little details would pick it up. Think about it, it all makes sense that, thats what happened, Tony didn't even realize it, he gets hit and his world goes dark.
