The introduction to the second season episode "If Memory Serves" uses archival footage of Nimoy as Spock from the unaired pilot episode "The Cage", and the third season episode "Unification III" uses archival footage of Nimoy again from the "Star Trek: The Next Generation" episode "". The latter appearance is a holographic recording from the records of Jean-Luc Picard, and is shown to Michael Burnham after she travels to the 31st Century, a time in which the Romulan and Vulcan peoples remember Ambassador Spock as the cause of their reunification on the planet Ni'Var, the newly renamed Vulcan.
