What to Expect from Slow Horses Season 6 Episode 5: Sayonara
Sid’s been taken by the assassins, and River’s on his own to rescue her on Slow Horses Season 6 Episode 5, “Sayonara.”
We’ve already gotten proof that Diana is not going to be helpful in this situation, and with Blake’s Grave in effect, River’s cut off from the rest of Slough House. Unfortunately, River is dumb enough to try to do this all on his own.
Perhaps a moment of clarity will strike him, and he’ll call Lamb for help. If any of Slough House is going to break protocol and answer a phone, it’ll be Lamb. There’s also a very strong possibility that Sid will do the heavy lifting and rescue herself.
We love you, River, but there is a reason you’re in Slough House.
Based on the released photos from “Sayonara,” it appears that Lamb, Roddy, Flyte, and Reece have made it to the safe house. It’ll be interesting to see how many of them actually remain there for the entire episode, or if any try to head back out.
Here’s everything you need to know about this episode, including the air date, cast, and photos.
