On that top video I still haven’t seen anyone explain the massive exit hole that appears at the back of the head.
I haven't seen anyone explain how the front of his head can be referred to as "the back".
You would have to ask others as it’s been a long time since I read up on all of this. Besides, everything conflicts.
I recall a quote from Jackie, waaaaay back, that she ‘tried to hold his head together’.
Something you can never forget. Then she crawled out on the back of the limo.......
