In Star Trek Beyond, Spock receives word that Ambassador Spock (Spock Prime) has died. Impacted by this, Spock later tells McCoy that he intends to leave Starfleet to continue the ambassador's work on New Vulcan. At the end of the film, Spock receives a box containing some of Ambassador Spock's personal effects, and reflecting on a photograph of the older crew of the Enterprise from the series' original timeline, he chooses to remain in Starfleet.
