The Killer (Hass) is the villainess of the 16 minute adult short video called "Babysitter" by Dark Rooms Studio. She is first seen intruding in the house of a woman doing a workout. She then grabs the workout girl and knocks her unconscious, and takes her to the couch. She ties the girl's hands behind her back and tells her she is here to avenge the death of a baby that the woman supposedly drowned. The woman protests that the court found her innocent but the Killer tortures her by forcing her head underwater so she can't breathe. She pulls the woman back up for air a few more times before finally killing her for good. The killer strips the woman of her clothes and takes a selfie with her corpse, and sends it to a man who is called "Father" in the credits; presumably the father of the dead baby.revealing she might be his wife and the babies mother.
- She speaks in Russian.
