What to Expect from Slow Horses Season 6 Episode 6: Judgment Day

Lamb and Diana have a plan to hopefully save her job and his Joes’ lives on Slow Horses Season 6 Episode 6, “Judgment Day.” 

Sid has seemingly escaped harm after River dropped her off in a random field and drove back to the swarm of people chasing them. Hopefully, River pulled off enough of a diversion, and he can make his way to the safe house knowing that Sid is okay.

Slow Horses Season 6 Episode 5, “Sayonara,” hinted that Frank and his henchmen, as well as the surprisingly alive female assassin, are approaching the safe house.

As much as I would love to believe that the female assassin is either in custody or hightailing it back to Russia, something tells me Slough House is not that lucky.

Here’s everything you need to know about this episode, including the air date, cast, and photos.
