The Gothic Stone: Karyn Wishes Jon Back

"_Your_ stone? No, that stone belongs to _Jon_," Karyn corrected Zoe. "Jon? Who's Jon?" Zoe asked, confused. "Your brother!" Karyn yelled. "Mikey's my only brother. I don't know anyone named Jon. Now give me back my stone!" Zoe yelled, before lunging towards Karyn's twin (who used to be Jon, even though she had no memories of that). Karyn suddenly realized what her twin had already figured out moments earlier - since Jon essentially no longer existed, Zoe probably would have been the one to inherit the stone. So it _was_ Zoe's stone after all. But that was easily fixable. She could just wish Jon back into existence, in some way. So with that, Karyn grabbed the stone (which was _actually_ the Gothic Stone) out of her twin's hand, before Zoe could get to it, then immediately said "I wish Jon existed again," causing the stone to glow a second later. The wish was granted, but in what way?
