In the Star Trek: Discovery midseason premiere, it was revealed that thanks to the spore drive the Discovery crew had accidentally traveled to a parallel Mirror Universe.
The United Federation of Planets will receive a new member on this week’s Star Trek: Discovery, “The Wolf Inside.”
The latest Star Trek: Discovery episode, ‘The Wolf Inside,’ airs on January 14, 2018.
As stated, the new images reprise the Mirror Universe-goatee on Sarek, which was first seen on Sarek’s son Spock in The Original Series.
