We’re still two days away from “What’s Past is Prologue,” the next episode of Star Trek: Discovery, but now we have a new preview of a coming Mirror Universe showdown thanks to a new clip released via IGN today.

In this new video, Gabriel Lorca — who we learned last week has a history with Emperor Georgiou in his home universe — makes his move to challenge Georgiou’s rule aboard the ISS Charon, while asking her followers to take his side… but leave Michael Burnham alone.

Interestingly, Lorca seems to be partnered with — or at least using — the Mirror Universe’s Paul Stamets to enact his plan, a move likely to involve the alternate version of Ellen Landry (Rekha Sharma), as seen in this episode’s promotional photos.

“What’s Past is Prologue” airs this Sunday on CBS All Access and Space, followed by a new After Trek with guests Jason Isaacs, Rekha Sharma, and writer/producer Ted Sullivan.
