The Parent Trap movie. So twins end up switching places and the powerful force users on both sides have no idea it happened.
Really, that's where this is going. Ugh!!!
And I do wish they would quit with making Jedi always look so weak against the Sith. So 5 or 6 Jedi can't take down a single sith until it gets down to one of them and then somehow that one person all of the sudden is good enough to stop them.
I've always hated that about the SW universe. The books do that a lot as well.
