George Hammond (Stargate) [SEP] Character arc
The series never clearly establishes Hammond's second-in-command, although producer Joseph Mallozzi stated in season 7 that "if Hammond were to retire, there's a strong possibility that [Colonel Jack O'Neill] could take over command of the [Stargate Command] base". In the season 7 finale "Lost City", newly inaugurated President Henry Hayes is pressured into replacing General Hammond with Dr. Elizabeth Weir for a three-month review process of the SGC. Hammond is promoted to the rank of Lieutenant General and is placed in command of the new Homeworld Security department afterwards; Brigadier General Jack O'Neill takes over command of Stargate Command in the season 8 opener "New Order".
