In "Doppelganger", Lorne threatens Sheppard while sleepwalking, believing him to be a Replicator. Lorne is stunned by Ronon Dex, and while being questioned by Dr. Kate Heightmeyer says that he "hadn't had a sleepwalking incident since he was ten." Lorne's mother, an art teacher, taught him how to paint on weekends when he was growing up, and Lorne rekindles this muse during his stay on Atlantis. In "Tabula Rasa", Lorne, while being semiamnesiac, takes a severe overdose of a delaying medicine that is supposed to hold back the illness. This causes him (and all of his team) to become paranoid, aggressive and confused and they resort to shooting with stunners everyone they see even if they are not affected by the sickness. Eventually, though, a picture of Sheppard convinced him to assist Ronon treat the sick. He later apologised to Sheppard. Originally from San Francisco, California, Lorne also has a sister who has two young boys. He loves ice cream.
