LoglineCaptain Burnham and Book journey into extradimensional space in search of the next clue to the location of the Progenitors’ power. Meanwhile, Rayner navigates his first mission in command of the U.S.S. Discovery, and Culber opens up to Tilly.
I'm kinda left wondering why it needed to be the Enterprise at all, since all we see is the ship, and no one from it. Is it just to give closure in-universe for it? Why couldn't it just be "any" mirror universe ship?
I mean, was Burnham so incurious about mirror Spock that she never checked the records?
