The Doctor isn't the only Time Lord River runs into on her travels up and down the timeline. The Master, in all of his - or her - guises, also has a chequered history with Professor Song.

It's something River must get used to: there are three people in her marriage - at the very least! 5.1 The Bekdel Test by Jonathan Morris Back at the start of her imprisonment, Doctor Song becomes a guinea pig for an innovative new security system.
