Raccoon City OutbreakEditZa'afiel attempted to force Bailey to work for them, kidnapping him in the process. Having military experience herself, Stella decided to personally rescue her fiancé, and she subsequently fought through and killed several Za'afiel guards. Za'afiel's leader, Eric Cunningham, decided to execute Bailey by shooting him in the chest and escape before Stella could reach him.
A few weeks after Bailey's death, Stella was contacted by Ayana Hamontree, who offered Stella a promise of vengeance. With limited options, Stella agreed to meet with Hamontree at the specified location. Upon arriving, Stella was shot with a tranquilizer dart, rendering her unconscious. When she regained consciousness, she found herself within a cell, stripped completely naked. Through a loudspeaker, Hamontree informed Stella that she must prove herself by fighting her way out of the abandoned building if she wants any help in killing Cunningham. With no choice, Stella picked up what she was provided within the cell, a Skorpion vz. 61, a combat knife, a pair of boots, and magazine carriers with additional ammunition, and began to make her way out of the facility.Stella killed several zombies, crimson heads, and lickers without suffering any injuries while navigating through the building. Once she reached the final room, which was filled with a larger concentration of zombies compared to the rest of building, she saw a zombified Bailey, who mumbled her name. While she was unable to bring herself to kill her former fiancé, she emptied her remaining ammunition into the skulls of the other zombies, until only six, including Bailey himself, remained. Just as Stella ran out of ammo, the zombies pinned her onto a table that was behind her, and then the zombified Bailey and the other five zombies had sex with her.
Hamontree announced to Stella that the zombies were under her command and that the human female was immune to zombification by the virus she made, the Hamontree's Tyrant Virus. In an effort to see what else her zombies were capable of, she wanted to see whether or not these zombies could produce children with live women and chose Stella as her first host. With Bailey being somewhat alive, Stella willingly accepted what Hamontree had subjected her to.
Given her fighting experience, Stella joined Hamontree's Security Forces. She continued to have sex with Bailey and other zombies until they impregnated her with a licker embryo. After being pregnant for two months, she gave birth to the infant licker, and over several months, it grew to adulthood while she trained it to follow her commands.
