Adrianna was a college friend of Lianne Mars and helped Lianne during her recovery from the mental institute and helped her look for Keith and Veronica Mars.
Personal assistant to Lianne[]
She helped Lianne when she was on the run but wasn't told where she went next because she wouldn't be able to keep a secret from Keith Mars. When Veronica Mars tracked her mother to Adrianna's house, Adrianna assured her that Veronica was all Lianna thought about. Veronica wasn't convinced. (Meet John Smith)
