Jay Roy was a friend of Osgood's, having studied with her at King Henry's University. He invited her to a pub quiz and then later on a date. He later noticed that all of their friends were starting to go missing. Osgood asked him to help with their investigations in order to keep him safe. They were at her flat when it was attacked by the Tengobushi. He decided to detonate the plasma device Osgood had in her flat to stop the alien from killing more people and died saving her.
