The movie does not provide an answer to what happened to Carol Marcus (Alice Eve). She was still aboard the Enterprise in the ending of Star Trek Into Darkness (2013) when the ship left for its 5-year mission, stating that she was happy to be part of the "Enterprise family". Star Trek Beyond takes place 2.5 years after Star Trek Into Darkness, but Carol Marcus is not referenced in the movie. According to behind-the-scenes stories, Carol Marcus was scheduled to reappear on Star Trek Beyond in the early script stages, based on ideas from producer J.J. Abrams. The movie was initially conceived as a direct sequel to Into Darkness and would follow-up on some of the plot elements introduced in that movie. However, during pre-production, writer and initial director Roberto Orci left, and writing duties were taken over by Doug Jung and Simon Pegg. When this new team chose to take the story in a totally different direction, most of the ties to Into Darkness were also removed. Carol Marcus' presence was probably omitted because they could not conform her to the new story. According to Eve herself, there is still a good possibility that her character will make an appearance in future Star Trek movies. In story terms, it seems most likely that Carol Marcus has left the Enterprise for unknown reasons prior to the events of Beyond. Edit (Coming Soon)
The alien warlord Krall is ultimately identified as a deformed Balthazar M. Edison, captain of the USS Franklin, a ship that, according to Scotty, disappeared without a trace in 2164, shortly after the founding of the United Federation of Planets. Edison is also identified as a former MACO (United Earth Marines), and mentions fighting during the Xindi War (2153-54) as well as the Romulan Wars (2156-60). Especially the mentioning of the Xindi War is interesting, because this places him directly on board the Enterprise NX-01, during the events of the third season of Enterprise (2001). He later states that he became disillusioned when the Federation was founded, and there was no apparent need for soldiers anymore. He received command of the USS Franklin in recognition of his services for Starfleet, and later disappeared. Some viewers have noted that this does not seem to conform to the official Star Trek timeline. If Edison received command of a ship after the Romulan Wars, how could she be a warp 4 ship? By the time the wars had ended, the Enterprise NX-01 and the Columbia NX-02 had already been flying with warp 5 engines for many years. So this is a potential error on the part of the writers of Star Trek Beyond.
However, there is a fitting explanation for this. According to the Star Trek timeline, warp 2.5 was achieved in 2142, and warp 3 in 2145. Since we know that the Enterprise NX-01 launched with an experimental warp-5 engine in 2151, the prototype warp-4 vessel USS Franklin must have been built somewhere in the late 2140s. This is sustained by several other observations: the ship is very close in design and size to the Enterprise NX-01 (relatively flat with the nacelles almost directly attached to the saucer section), she has transporters that were only used for cargo (the Enterprise NX-01 was the first with a transporter that could also transport humans), and she still has conventional torpedoes for weapons (the Enterprise NX-01 started out with these, but soon switched to photon torpedoes). So the USS Franklin must have been used as a cargo ship long before Edison received command of her. By that time, she must have been at least 11 years old, capable of only warp 4 and without transporters for personal transfer. Since Edison was already angry about losing his career as a MACO, being offered an obsolete ship may have added to his frustration. Edit (Coming Soon)
