In "Star Trek Into Darkness", Spock Prime is described as living on 'New Vulcan' while the younger Spock remains aboard the "Enterprise" struggling with the loss of his homeworld, as well as his relationships with Uhura and James T. Kirk. Spock nearly dies protecting a planet from an active volcano, but Kirk breaks the Prime Directive and saves him. Spock Prime is contacted by Spock on the "Enterprise", to find out details on Khan. Spock Prime initially reminds his alternate self that he will not interfere with the events in the alternate timeline. That being said, he then informs Spock that Khan was a dangerous man, and the greatest threat that the "Enterprise" ever faced in his own timeline, and warns that he is likely as dangerous in Spock's alternate timeline as well. When asked whether Khan was defeated, Spock Prime answers that he eventually was defeated, but at great cost (referring to the events of ""). When Kirk contracts radiation poisoning and dies in front of Spock (a transposed parallel of events in the prime timeline where Spock dies in front of Kirk), an enraged Spock attempts to kill Khan to avenge Kirk before Uhura informs him that Khan's regenerative blood can revive Kirk. Nearly a year later, Spock remains as Kirk's chief science officer and executive officer as the "Enterprise" departs on its first five-year mission of deep-space exploration.
