Dr. Carol Marcus first originated in “Star Trek II: The Wrath of Khan,” portrayed by Bibi Besch. She has a romantic relationship with Captain Kirk (William Shatner), and the two have a child together. “Star Trek Into Darkness” doesn’t explore their relationship too much, other than the Kelvin Timeline Kirk (Chris Pine) sneaking a peek at Carol when she’s almost nude. Suffice it to say, there are still plenty of avenues available for the character in this new continuity, so Alice Eve could return for “Star Trek 4” if it eventually happens.
In 2013, Eve spoke with Impulse Gamer about reprising her role. She said, “I’d love to become an integral member of the crew.” Of course, that quote’s from over 10 years ago, so there’s always a chance Eve could be too busy with other projects to sign on for another Star Trek. Even then, there could still be ways to incorporate the character into a sequel’s storyline. With so much time passing since “Star Trek Beyond,” perhaps Kirk and Dr. Marcus got together off-screen and already have their kid. It would put an intriguing wrinkle into Kirk’s characterization if a child is waiting for him to return from another dangerous mission.
At this point, fans likely just want “Star Trek 4” in any way, shape, or form. Having Dr. Carol Marcus there in any capacity would be the icing on the cake.
