Okay, so we all know Jango is decapitated by Mace. Here is a possible foolow up to that for EPIII. Boba kills Mace by disinegration (sp?). He certainly would have motivation and reason to.
Samuel L. Jackson has stated that he wants to die in a grand style. To close a hole George could have Boba kill Mace as previously mentioned tying in the line from Vader during the gathering of the bounty hunters, saying "I want them alive (turns to look at Boba Fett, and points) no disinegrations"
I know Hayden Christensen has said he wants to kill Mace but he has the chance to kill many Jedi. By having Boba do it we will clearly see why he is the"most fear bounty hunter in the galaxy" .
what say you?
