A Reasonable Man

 was the thirteenth and final episode of Series 5 and the 65th episode overall.

Plot
A schizophrenic man arrives after a road accident but it transpires he has murdered his wife's friend. He panics at the sight of a policeman and pulls a gun from a briefcase, taking Megan hostage in CRASH. He insists that a porter (Charlie in Jimmy's uniform) takes out a dead body on a trolley. Megan stays calm but the police and the man's wife's shouts make him panic and fire the gun, wounding Charlie in the chest.
