*The memory stamp is not permanent, and slowly SG-1 begins to experience vague and fleeting glimpses of memories hidden just beneath the surface, memories that convince tehm that they don't belong there. As their wor within the underground facility earns them Brenna's respect, the fleeting glimpses become more pronounced, and the gradual recall of their identities begins to threaten Calder's plans. Brenna offers them a means of escape, and in overthrowing Calder, SG-1 reveals the surface city to the workers below, offering them freedom from their harsh existence.
