We’ve got just two episodes left until Star Trek: Discovery warps off our screens until 2019, and ahead of this Sunday’s “The War Without, the War Within,” we’ve got a new set of photos to pique your interest until the weekend.

With the Discovery back home — only nine months late, in time to see the devestated Federation facing Klingon invasion — Admiral Cornwell (Jayne Brook) returns to the ship after last been seen in “Into the Forest I Go.”

“The War Without, the War Within” airs on Sunday on CBS All Access and Space, and debuts globally on Netflix this Monday.
