In regards to Appollonia and Michael having a child. If you read the section reight before she is killed, it says that she is pregnant with Michaels child. Any child that she was carrying died with her. However the book also specifies that when Sonny was killed and Lucy attempts suicide they ask her many times if pregnancy was the reason for the suicide attempt and she says no. She eventually winds up with the Dr. in Vegas, and yet in the movies we have Sonny's child by Lucy, Vincent. So the movies and the book do differ. Of course, it was the original author doing the differing.
