Yates's Guard

Yates' guard worked for Jocelyn Stevens who kept Captain Mike Yates under observation. He was tricked when Yates used the Metebelis crystal to hypnotise the guard, and managed to escape.

The credit for Brian Justice on episode four incorrectly reads 'Yate's Guard', instead of the grammatically correct 'Yates's Guard' which appears in Radio Times.
