When Professor Beaumont asks to use the doctors' flat for the afternoon, Duncan assumes it's to entertain his bit on the side and when Griffin overhears Duncan tell Dick, he is only too happy to lead the professor's wife to the flat. In fact the young lady in question is the professor's niece, whom he is helping with her exams, but Beaumont doesn't want his wife to find out, so when Dick arrives with his card school, Beaumont joins in. Soon Mrs. Beaumont has taken his place and is winning money from everybody at the table.

The animosity between Duncan and Maurice Griffin intensifies when Griffin gets slapped by a nurse's irate mother after she is told he is Duncan. Both doctors squabble over who should have priority in the operating theatre with their respective patients but it appears they have mixed the patients up and performed an operation on a man who does not need one. In fact the orderlies mixed up the name tags but Professor Beaumont allows the doctors to believe they are in the wrong so that he can transfer them - and Stuart-Clark - to Casualty.
