I love these kinds of thought processes.
What if Leia got stunned and caught before she managed to get to R2?
What if the Jawa's scrapped R2 to pieces for parts?
What if Jedi Sifo-Dyas didn't order the commission of a clone army?
What if Windu actually struck and killed Palpatine?
And the ultimate and most annoying.. What if Jar Jar didn't get banished from his home??.....
