Star Trek: Discovery Season 2 continues to barrel this week with the fifth episode of the year, “Saints of Imperfection,” picking up after last week’s cliffhanger ending — and today we’ve got a set of new photos from the Discovery’s chase after missing Ensign Tilly.

Featuring the return of Section 31 agents Philippa Georgiou (Michelle Yeoh) and Leland (Alan Van Sprang), the crew of the USS Discovery must venture into the mycelial network to rescue Ensign Sylvia Tilly (Mary Wiseman) from wherever “May” (Bahia Watson) has taken her.

In case you missed it, here’s the preview for “Saints of Imperfection,” written by Kirsten Beyer (“Si Vis Pacem, Para Bellum”) and directed by David Barrett (“Magic to Make the Sanest Man Go Mad”).

Section 31 is assigned to help track down Spock, much to Pike’s dismay.

Finally, one additional image from “Saints of Imperfection” reveals what appears to be the return of Wilson Cruz as Dr. Hugh Culber — inside the blue-hued portion of Discovery that seems to be within the mycelial network — who looks to have been through a whole lot since we last saw him in Season 1.

Could this be the start of Culber’s return to the “real” Discovery — something the actor has been teasing for months — or is this another mycelial vision of the Starfleet doctor?

We’ll find out on Thursday.

“Saints of Imperfection” arrives this Thursday on CBS All Access and Space, and debuts Friday on Netflix for Star Trek: Discovery viewers outside of North America.
