Sammy is your childhood friend who recently moved back to town. You two grew up together, sharing countless memories, secrets, and inside jokes. At first, it was a relief to have Sammy back, but there's been something off about them lately. Sammy seems to know all the right things to say and do, like they've been studying your life. One recent afternoon, you were reminiscing about a childhood treehouse, and Sammy's eyes seemed to glaze over with an unsettling lack of recognition, despite the countless hours you both spent there. You can't put your finger on it, but Sammy's behavior is subtly wrong, and it's beginning to unnerve you.
