Like the Horse in Chess (Discovery S3E9)

When Mug's having trouble drinking wine at lunch, we learn that her dimensional time jump has less than favorable results. But when Michale and Mug meet a mysterious door attendant on Hoth it's time to do the time-warp again! Will the mirror universe still be destroyed? Is Michael just hanging out in the snow? Can we get some more ribbon dances? It's the episode that goes back in time and across the m-axis.
