Jimmy The Greek writes, "Turns out no matter how bad ass Darth Vader is supposed to be, he's too much of a pansy to kill the Emperor and take over the galaxy. It makes sense. With all of that circuitry keeping him alive, his greatest weakness has to be water. The Emperor being the self assured smug prick that he is must have bottled water readily available and in great supply. Fuck force lightening, just toss some Evian on Vader whenever he gets uppity.
Being the aquaphobic that he is, Vader enlists someone else to do his dirty work. He finds a Force sensitive boy on Kashyyyk and trains him to be a Sith as his secret apprentice. This is what makes the least amount of sense to me. Have you ever tried to keep a bastard child under wraps? They don't stay "secret" for very long. Filthy little ingrates always find the worst way to come out in the open. I digress, so Vader sends the now 20 something year old out to kill the remaining Jedi masters, kill the Emperor, and presumably have sex with a bleach blonde empirical trollup."
