Sarek wasn't in Star Wars. Therefore, your suggestion isn't valid.
Of course he wasn't. He died offscreen, and cheap fuck that he is, Lucas didn't want to pay royalties to Roddenberry, that's why even the most moving and emotional funeral scene in all of Science Fiction with Spock breaking down and shouting at Solo to have some compassion in the eye of tragedy was taken out prior to release. Extra special edition Blue Ray HFS DVD with deleted scenes coming out in June 2013!!
Too many trekkies on the fucking internet.
I can't seem to get away from them. They are everywhere.
Star Trek sucks. Passe. Dig?
Live Long and Prosper.
