Leena (Genelle Williams). Despite Leena's youthful appearance, it is implied that she and Artie have had a relationship that long pre-dates the series's start. In one of the few glimpses we have into her past, Leena states she was not yet around when everything went down between Artie and MacPherson. Artie and Leena spend frequent time together in the Warehouse, usually working but sometimes just enjoying one another's company. Artie values Leena's opinions and frequently relies on her aura-reading ability, often deferring to her. Leena also maternally looks after Artie, such as making sure he eats right. In the Season 4 episode "The Ones You Love", Artie. Through the use of Magellan's astrolabe, the latter is taken over by an evil personality, killing Leena by gunshot as she tries to help him. After being freed from the astrolabe's control, Artie feels great grief and guilt over Leena's death, knowing that it was his hand that killed her. In the episode "The Sky's the Limit", he seeks the consul of psychologist Abigail Cho, telling her, "I killed someone I love, and I don't know what to do."
