CBS released a lengthy video today on its Facebook page showing the long, arduous work that went into constructing the massive and intricate USS Discovery bridge set — and at the end of the 35+ minute time-lapse sequence, a first look at “Despite Yourself,” this weekend’s newest Star Trek: Discovery episode.

While the video is region-locked to the US through the official Discovery Facebook page — so unfortunately we can’t embed it here — below is a transcript of the clip (starts at the 36-minute mark) and selected images from the short minute-long preview, which begins right where “Into the Forest I Go” left off: with the Discovery floating in a field of debris.

Pan through the debris field into the Discovery’s main viewscreen window. LORCA: “Yellow alert. This isn’t Starbase 46 — where the hell are we?” COMPUTER: “Yellow. Alert. Yellow. Alert.” OWOSEKUN: “A vessel is approaching at sublight speed.” TYLER: “Seems like a Vulcan cruiser.” LORCA: “On screen.” BRYCE: “Should we hail them, sir? LORCA: “Yes — open a channel.” BRYCE: “Unidentified Vulcan cruiser, this is the USS Discovery, please respond.” TYLER: “Captain, the Vulcans are powering up weapons!” BURNHAM: “They must have registered an active Klingon ship somewhere nearby.” LORCA: “Red alert! Shields up!” The Vulcan ship opens fire.

What danger does the Discovery pose to these Vulcans — and is that even a Vulcan ship that Lorca and crew might be familiar with? We’ll find out when “Despite Yourself” premieres this Sunday night.
