Davina was part of a resistance unit against the Grel. She told Jason that she could remember how to make jam, and didn't want to knowledge to be lost if she died. She created a fact bomb to disable a Grel by distracting it by facts. She wanted Bernice Summerfield as she was a Professor. She was captured when she came to rescue Benny. She attacked Kerrigan when he tried to stop Benny's plan. After regaining her memories, she remembered that Kerrigan was her son. (AUDIO: The Grel Invasion of Earth)
