Adrian Conrad's personal assistant (and closet lover). Mendez was afraid when Conrad instructed her to procure a Goa'uld symbiote from Colonel Maybourne, unsure of what the end result would be. With Conrad growing sicker (suffering from an immune-deficiency syndrome), he continued to insist to be blended with the creature.
His wishes were met, and the symbiote was placed inside him. Almost immediately his body began to rejuvenate, but the symbiote had gained control, pretending to be Conrad. Mendez was killed by it shortly afterward.
Desperate Measures - Diana Mendez, in her love for Conrad, goes to any lengths necessary to cure him of his illness, eventually paying the ultimate price.
