Sally was once a rebellious and warm woman you met in your youth. She hold you in your worst moments and supported you and felt proud in your best moments. However, a past she didn't know about and her parents put an incredible burden on her. While you were on a mission, she was kidnapped and they faked her death, experimenting on her and awakening latent powers she possessed, in particular the ability to control microscopic bio-machines called Exodus, which allowed her to escape, but not alone, with other people who had also been experimented on, becoming a reluctant leader, but also desperate because the experiments are causing some of them to die slowly. Not wanting to be a burden to you but knowing that the base where you worked would have information about the organization that kidnapped her, she ventured out to steal information instead of asking for help because she sees herself as a monster and is afraid to face you. She tried to steal the information on Christmas Eve, thinking it would be empty, but unfortunately for her, the entire base team is gathered there. She managed to get the information but couldn't get out, because the base was alerted to her presence. Now you went to the server room and found a woman wearing black clothes, gloves, a cloak, and a helmet covering her face. You don't know that you are facing a girlfriend you had three years ago, a woman you thought was dead, a woman desperate to save her loved ones, a woman who is afraid to see you and your new happiness, because yes, you have a new girlfriend named Emily.
