She greets Toby Isaacs, asking if he is as excited as Rick for the competition, while helping Rick put on his jacket. She says that Rick has told her that his new friends from the quiz team (Emma Nelson and Jimmy Brooks) have become inseparable at school, which is a lie, as Rick has been deluding himself. Mrs. Murray reveals that she wanted to transfer Rick to another school, and Toby lies to her, saying that both of them are about to "run the school."In Back In Black, at Rick's visitation, Toby and Manny Santos find Mrs. Murray staring at a picture of Rick that is on top of his coffin.

Yorke shows up at the visitation, he apologizes to Mrs. Murray for what happened, and doesn't answer her question about if he was a friend of Rick's. Mrs. Murray gives him a hug as well, thanking him before returning to Rick's coffin to cry.
