Sid Baker Makes Shocking Return in 'Slow Horses' Season 6 Episode 2

The second episode of "Slow Horses" Season 6 delivered a significant surprise for fans with the unexpected return of Sid Baker, portrayed by Olivia Cooke. Baker, who was last seen in Season 1 and presumed dead, reappeared in the closing moments of the episode titled "Daddy Issues," leaving viewers and the show's protagonist, River Cartwright, in a state of disbelief.

During Season 1, Sid Baker was presented as a key operative who accompanied River on a mission to rescue a kidnapped student and surveil journalist Robert Hobden. In a critical moment, Sid was shot while covering River's entry into Hobden's house. Though initially indicated to have survived, the show later confirmed her death. However, the Season 6 cliffhanger revealed Baker alive and well, standing at the top of a staircase as River entered his grandfather's house.

The return of Sid Baker aligns with events in the book series by Mick Herron. In the novels, Sid's storyline takes a turn after her injury, and she ultimately reappears in the seventh book, "Slough House." Her survival was hinted at in the show when Roddy, a tech specialist at Slough House, discovered that no records of Sid's hospitalization or existence could be found in official databases, suggesting she might still be alive.

Beyond the immediate shock of her return, Sid's character had established a compelling dynamic with River Cartwright in the first season. Their witty banter and evident chemistry hinted at a potential partnership, both professionally and personally. Sid was depicted as a quick-thinking agent who challenged River, and his apparent crush on her was a recurring element.

The reappearance of Sid Baker sets the stage for significant plot developments in the remainder of "Slow Horses" Season 6. "Daddy Issues" also featured Frank Harkness, played by Hugo Weaving, making a return, along with Diana Taverner's reluctant interview for Damien Cantor's news station and an assassination attempt on Moira.

The next episode of "Slow Horses," Season 6, Episode 3, is scheduled to premiere on Tuesday, September 29, at 9:00 p.m. ET on Apple TV. The streaming service offers a seven-day free trial for new subscribers and a single ad-free plan for $14.99 per month. A bundle including Apple TV and Peacock is also available starting at $14.99 per month.
