Re: Daddy Kirk (spoilers probably)
Where is Kirk's brother through all of this? Is he even in the movie?
My guess is some actor will play him in a brief appearance when Kirk is growing up or leaving for the Academy...that, or he'll be mentioned if nothing else. Too many fans both hardcore and passing remember Kirk had an older brother.
Human instinct is pretty strong. You can't expect us to change overnight.
