Daniel Dickinson (Simon Reynolds). Artie experiences some difficulty with Dickinson in the series' early episodes. Dickinson first tries to get his agents transferred back to Washington, and then Pete and Myka contact Dickinson for help on a Warehouse case, forcing Artie to forbid further contact. In the episode "Resonance", Artie accuses Dickinson of hacking into the Warehouse computers, though it is later discovered the breach was initiated elsewhere. Despite their difficulties, it is never personal. When Dickinson is murdered in the season 2 episode "Vendetta", Artie feels remorse when he discovers that the murder weapon was an artifact he had traded to the Soviets.
