Appollonia's death was one of the only times that I felt any sympathy for Mike. I believe that he truly loved her. She would have been a dutiful,faithful wife who would have given him as as many children as he wanted,made a beautiful home,and above all,wouldn't ask stupid questions like "Miguel,is it true". No doubt Signor Vitelli was well acquainted with Mafia protocol,and would have had a talk with her before the Ceremony. In their world,she hit the jackpot by marrying a man of Michael's status. To have a son-in-law like Mike wasn't anything to sneeze at either. If by chance Signor Vitelli would make an enemy,then they would become Michael's enemy,and then they would fear Vitelli.
