After three months, the second season of Star Trek: Discovery is about to conclude the story of the Red Angel, the Seven Signals, and Captain Christopher Pike — all part of the “game-changing” Discovery season finale, “Such Sweet Sorrow, Part 2.”

As the combined might of starships Discovery and Enterprise prepare to take on Control’s Section 31 forces, Captain Pike (Anson Mount), Number One (Rebecca Romijn), and Admiral Cornwell (Jayne Brook) lead the Federation flagship into battle.

Meanwhile, back aboard the DiscoveryCommander Burnham (Sonequa Martin-Green) prepares for her dangerous flight into the future as Section 31’s Agent Georgiou (Michelle Yeoh) hangs on tight during the tumultuous fight against Control.

And in case you missed it, here’s the video preview for the episode, which features the return of Number One and the USS Enterprise as the starship joins the Discovery in a team-up against Control and its Section 31 assets.

 

SUCH SWEET SORROW, PART 2 — Season two finale. The U.S.S. Discovery battles against Control in a fight not only for their lives but for the future, with a little help from some unexpected friends. Spock and Burnham discern vital new connections between the red signals while Burnham faces one of life’s harshest truths: the right decisions are often the hardest to make.

The episode features a story Michelle Paradise & Jenny Lumet & Alex Kurtzman, and is directed by Olatunde Osunsanmi — the same team as last week, as this finale expanded from an originally-planned one hour to two.

In addition to these photos looking ahead to Thursday, we’ve got some new behind-the-scenes photos from last week’s visit to the USS Enterprise bridge set, thanks to a few members of the guest cast — and a moment of humor between Anson Mount and Sonequa Martin-Green in the Discovery cargo bay.

I have no words to describe the immense pleasure it was to work on one of the most recognizable franchises in the world, @startrekcbs . It's always, always the people that elevate the project and instill any kind of lasting impression upon me when I work. I have to thank @therealsonequa (sadly not pictured, but my memories never fade), for being such a welcoming lead, telling great stories and encouraging the best from us. Olatunde Osunsanmi @olatundeo , a fantastic director at the helm of this ship, he's stoic, hilarious, and generous. Finally, to @samoragloria and @hanneke.talbot , couldn't ask for a better team of lieutenants. Guys we ain't even done yet. There's one more episode… Buckle up. . . #startrekdiscovery #cbs #scifi #enterprise #commsofficer #holyshitiminspace #pewpew
