Nobody killed Tony, he's still out there. It was the viewer who was whacked since we saw it from our POV not Tony's.
We see a lot of things from Tony's POV in that scene. It goes from his POV to ours and then to his. It ends in his POV.
Long as I remember The rain been coming down. Clouds of Mystery pouring Confusion on the ground. Good men through the ages, Trying to find the sun; And I wonder, Still I wonder, Who'll stop the rain.
