6x9 - The Royal

A piano teacher (guest star George Costigan) remains suspiciously secretive about his past when brought in to casualty after collapsing outside the hospital. Matron's revelation about Susie cools Alun's interest in her, and Mike takes pity on a mother while he treats her son. Elsewhere, Jill delivers bad news to an elderly patient and the porters are forced to take industrial action in support of a colleague.
