TM -- are you among the anti-Grievous fans? I have to count myself as tickled to death by Grievous in Episode III. I found his final battle with Obi Wan to be one of the emotional highlights of a movie I thoroughly enjoyed.
...But what if his android body were built out of the damaged remains of Lama Su... I can't even make it work for a second.
But here's one that would twist the whole PT -- what if Grievous were Qui Gon?
Nah.
Why wasn't he Darth Maul?
I'll go away now.
