Near the end of the Siege of Cask, Ayers analyzed the corpses of dead zerglings beyond the defensive barriers. Delme believed Ayers might have been committing suicide. Ayers discovered an explosive component within a zergling's corpse while autopsying it, causing her room to explode. Lt. Travis Orran believed this was a suicide attempt, and Delme was assigned to watch over Ayers.
Ayers had contacted the Terran Dominion with this information, and believed the Dominion would finally come to rescue them. Delme didn't seem to believe her, however. Delme was considerably relieved when Lt. Orran let Ayers out of confinement due to her boredom.
In the final battle, only Lt. Orran and Maren Ayers made it out alive.
