Re: STAR TREK INTO DARKNESS - Grading & Discussion [SPOILERS]
If we wanted to have the lonely, slightly emotionally bitter Kirk, bound and wed only to his Enterprise, then Marcus would be his Rand. Don't see that happening, though. This Enterprise has the potential to be either the Love Boat, or it recreates the Picard-Crusher (Kirk-Marcus), Riker-Troi (Spock-Uhura) relationships.
Or Marcus gets assimilated by the Borg in the next movie. Moving Kirk towards the character we know him to be in TOS.
