Ros' introduction to the team

[Silktie]

See, to me the way they introduced the character creates a significant problem. There is no way in Hades that someone involved in a coup plot against the government will be brought into the Security Services so smoothly or quickly. Not to mention the fact that she betrays them a SECOND time during S6 by working for the Yalta group - and still she becomes team leader once she's back in S7?! Now I know that it's only a show and not reality, but to me loyalty to your country and your colleagues is a fundamental part of the show, so I have a bit of a problem with the way her betrayals are just glossed over.
