Episode 5.5 [Rewatch]

[Kirayuki]

This episode makes me really notice how good the inclusion of Mace's character was in these episodes. He's a great character for Harry to Sapr with and it's nice to see that.

I agree with Ros trying to make it up to Harry in the future. I also think she knows her mistake by the time she switches places with Ruth in her house. I think Ros wanted to apologise despite only following the correct course of action. (Apart from the going over Harry's head to the JIC bit).

I think Ros remembers this as

Series 8 Spoiler: show

when Malcom says he got a call from Ruth she looks shocked/confused but sort of also happy that she is in fact alive. In my opinion anyway.
