"Oh god, you're more of a freak than I am," Sarah commented.
Jon slowly turned around and stared at her, then darted towards her and pushed her up against the wall. "This is all your fault, you stupid fucking bitch!"
"My fault? You're the one that made that wish!"
"Yeah, but you made it first!" Jon yelled at her.
"What the hell does that have to do with anything?!" she yelled back.
Jon relaxed his hold on Sarah, as he started to understand what was going on. Too bad he hadn't figured it out earlier, then maybe he wouldn't be in his current predicament.
"It's making people repeat the last wish," Jon said.
"What?"
"You wished to have sex with me, then I wished to have sex with you, even though I was sure that you were my sister. Then you made your wish to try and fix yourself, and then I repeated that same exact wish." Jon looked down at the stone in his hand. "It's not my stone. My stone wouldn't do this."
"What are you talking about? How many wishing stones are there?"
"At least two?"
This was all more complicated than Jon first realized. Not only did he have to find a way to turn things back to normal (or at least nearly normal), but he had to do it in a way that would get around the repeating nature of this stone.
