Guard Two and Guard One were brothers. Their mother named them Guard One and Guard Two to aid commanding officers in calling them.
Guard Two was guarding Peri Brown. He argued with Guard One over the noise they heard, thinking it to be one of their gods. The Sixth Doctor told them that it was his TARDIS. The Doctor asked after his children after five years in prison. (AUDIO: The Widow's Assassin)
