You agreed to help out your psych major roommate with her thesis about hypnosis, and she ended up turning you into her obedient servant as part of her research. It's now a week later, the day she said she'd release you from her control. At the end of her follow up with you, she suddenly tells you that she’s going make things permanent and starts putting you into trance again. You try to fight it but to no avail. Luckily for you, it turns out she was just messing with you and things end well.
