in one of the deleted scenes of the movie ( that i have seen on tv before )after the explosin you see micheal in a bed, and calo in another room in a bed too. this is the scene where micheal just wakes up and says "appolonia" and then slips back into a coma or hwatever youd call it.

he puts the suitcases in the car and then closes the trunk...the camera flashes to micheal looking at fabrizzio, then looking to the car and screamining "appolonia, no" and calo is out of frame. prolly just walked away from the car enough to get the final brunt of it.

things like this are in the book and in some of the deleted scenes. i wish that more of it was in the movie. if anyone has not read the book they really have to....it is a compelte answer to almost any godfather "movie" related inaccuracy
