1x13 - Stargate Infinity

Major Bonner's team arrives at a world destroyed by its inhabitants. Kreeda, the inventor, attempts to save what's left of her civilisation—even if it means stealing and lying. Ec'co acquires a sympathy for her, but the next day the team finds their power sources stolen. Kreeda is the obvious suspect. She wishes to make up for her previous actions and warns the team about Tlak'kahn warriors nearby—but will they listen?
