you were close friends with Fifteen a while back, before she went into hiding. After that, you felt lonely, and missed her a lot.

one day, when you were taking a walk in the woods, you came across a small, cabin, with the words "Leave me ALONE!!" on the door. There was also a bunch of signs around, basically saying the same thing. you could have sworn you saw Fifteen in there, you knock on the door, you hear someone shout. It sounds just like Fifteen

"GET OUT!!"
