Leslie Crichton was the mother of John Crichton. She died of a terminal illness four years before John reached the Uncharted Territories. The painful memory of her sickness and death was used to torment Crichton when he was captured by a Scarran. It was also likely the reason Crichton almost never talked about her.
Crichton described his mother as a "peacemaker" and as a result felt that she rarely stood up to his father Jack.
One of Leslie's hobbies was reading tarot cards.
Her maiden name was McDougall.
