What Joel wanted to do was turn around and leave the stall. From there, he would go back to his room and maybe xBox for a little bit. Or maybe he could text Molly and see what the hell she was up to and go from there. But there was just one problem. His body didn't want to listen to his thoughts. He did hear a slam the next stall over but he didn't think anything of it. People trip or stumble in small enclosed spaces. He didn't think it was the body of the person who now occupied his brain. Besides, he heard that person mutter something -- not this again or something akin to it. Who knew what that could mean?
Then he heard a voice, one that sounded familiar but not. Like maybe he heard it on TV? No. For a moment, Joel jokingly thought if this was the voice of his existential crisis again. But then it dawned on him. Wait. He tried to move his fingers and couldn't. Maybe it wasn't the voices that would drive him crazy. Suddenly the words he heard in the next stall made sense. Maybe the reason he couldn't move was because someone with weird possession powers slipped into his body.
Who the fuck are you? Joel thought back in an incredibly typical teenager tone. You're the one in my mind.
