Early in the episode Luther is told that the serial killer he put in a coma (at the start of episode 1) has woken up. He goes to Alice to tell her he can't see her any more because his phone and email will be monitored. Alice doesn't take it very well.
Alice disguises herself as a doctor and manages to get the policeman guarding the serial killer to go to another ward. Then she smothers the killer so she and Luther can be together.
When Luther finds out he Smashes Stuff again. Brilliant.
She also breaks the news to Luther's ex-wife's boyfriend that the ex-wife is cheating on him (the boyfriend) with her ex-husband. Yes it's complicated.
Once again Ruth is great as Alice Morgan, coldly calculating and just on this side of barking mad.
As an added bonus here is a nice photo of Ruth from the new issue of the Radio Times.
