From what I read, Orci denied that Cumberbatch was Gary Mitchell. He said that Karl Urban was testing hypospray himself. But Cumberbatch's character is canon.
if the cover is Kirk/Pine, he has an evil eye.
Lol....well maybe they are remaking The Enemy Within but the transporter accident happens when they are in the great barrier. That could explain the evil eye on Kirk.....if it is him!!!
