[Hmmm. Well, I suppose Jon and Karyn could have gone back to Jon's house, and to his bedroom, without the story mentioning it. But OK, let's say that Zoe was in the school bathroom and go forward. Jon's mother could have been there for a routine conference with Zoe's teacher, or for any number of other reasons, such as talking to the principal about Jon's breaking the rare historical artifact...]
"So, does that explain why I have, like, a dick now?" Zoe asked in her usual standoffish voice.
"Yeah, it probably does," Jon decided. "Zoe, from where you were in the girl's room to where we were in the library must be over a hundred feet. I wonder who else was within range?"
"Moe Munson was in the washroom," Zoe stated.
"You mean in the boy's room, right?" Karyn asked. "Did you see him go in? Is that it?"
"Uh, no, he was with me," Zoe admitted. Then, in reply to Jon's stare and Karyn's raised eyebrows, she continued. "We were in, like, the same stall. OK, I was like givin' him a blow job and then all of a sudden he had tits and then he got all freaky about it. Well, freakier than usual. Then we both noticed my, like, dick, and that really wigged him out. He stepped down to the floor, peeked out, and then he ran to the last stall in the row. I guess he's still there, feeling up his new tits or somethin'. They're bigger than mine, you know, but he never thanked me for 'em. Never thanked me for the blow job either. Seems kinda rude when you think about it."
"What about the statue? Did you do anything special with it, such as holding it and making an incantation or wish?" Jon questioned Zoe.
"No, man, or whatever, or... Uh, look; I just set it on the toilet paper holder, that's all. I s'pose we coulda shook it a little or something but if we did, it was unintentional. Anything else you wanna know? Cause I gotta pee."
"No one else was in the girl's room, right?" asked Karyn.
"Just mom, "Zoe explained, then she scratched her balls through her skirt and wandered vacantly into the boys' room.
