In "Smallville", the series incarnation of Jimmy Olsen is first referenced in Season 2 by Chloe Sullivan (Allison Mack), when she refers to a "cute boy" who's "name is Jimmy", whom she met in Metropolis that made her forget all about Smallville for the summer. His name is first given in Season 4 when Chloe confides to Lana Lang that he was her "first time". In Season 6's premiere "Zod", Jimmy appears in person (portrayed by Aaron Ashmore) on the staff of the "Daily Planet" and prefers to be called "James", and frequently addresses Clark Kent as "CK". As Season 6 progresses, Jimmy and Chloe rekindles their old romance again. At first Jimmy is jealous of Clark but their relationship becomes friendly after Clark reunites him with Chloe in the Season 6 episode "Trespass".
