Star Trek: Discovery continues this week with “If Memory Serves,” the eighth episode of the season, and we’ve got a set of new photos from the next chapter of this year’s story — including the trip back to mysterious Talos IV.

This week we’ll revisit the story of Paul Stamets (Anthony Rapp) and Hugh Culber (Wilson Cruz) as the recently-resurrected doctor continues to adjust to life back in the land of the living — all while having to face Ash Tyler (Shazad Latif) who killed him under Voq’s control.

'Star Trek: Discovery' -- Episode 208: 'If Memory Serves' 1 of 8

While the Discovery bridge crew works at a yet-uncertain task (likely related to the ongoing Red Angel mystery) with Airiam (Hannah Cheesman) under the influence of the time-traveling probe seen in last week’s episode, Spock (Ethan Peck) and Michael Burnham (Sonequa Martin-Green) look to reach their destination of Talos IV — and the pair also seems to make a return journey to the Discovery to reunite with Captain Pike (Anson Mount).

And in case you missed it, here’s the video preview for the episode, which features Spock and Burnham encountering the telepathic Talosians, seen in Star Trek this week for the first time since 1966’s “The Menagerie.”

IF MEMORY SERVES — Spock and Burnham head to Talos IV, where the process of healing Spock forces the siblings to confront their troubled past. Stamets desperately tries to reconnect with an increasingly disconnected Hugh, while Tyler struggles to shed the crew’s suspicions of him due to his past as Voq.

The episode features a story Dan Dworkin & Jay Beattie and is directed by TJ Scott, who also helmed last season’s Voq/Tyler-heavy episode “The Wolf Inside.”

“If Memory Serves” debuts this Thursday on CBS All Access and Space, and beams to Netflix around the world on Friday.
