Ros' introduction to the team

[JHyde]

I completely agree that Ros was in the wrong about dobbing Ruth into Mace. I do, however, think that Mace would have got to Ruth anyway, Ros just offered him the easiest possible route. (Part of the reason Ros was bothered was because she knew exactly that.)

This is probably why Harry, Ruth and Adam all seemed to move on, at least on camera or as scripted.

I also think that one of the reasons I'm not crazy about season 5 Ros is that she doesn't accept personal responsibility at all.

Series season7 Spoiler: show

I think season 7 Ros does and one of the reasons why I like her a lot better later on.
