Eric was too busy kissing to notice the grin on Keith's face. Keith had decided that Eric had too many chances at using the stone, while Keith barely made any wishes at all. This was his chance to make things more in his favor.
"I wish ... that Eric would become my girlfriend," the second part Keith raced through to give it emphasis. He wanted Eric to hear it.
Eric stopped kissing. "What?!"
The stone flashed. And in place of Eric was a girl that resembled him.
"I wish that your name is and always has been Erika and I wish that even though you still have the memories of Eric, you desire to act and think as girly as possible." He paused to let the stone grant his wishes. "Erika."
"Yeah, baby?"
Keith smiled. But there was a problem. Eric's previous wish made Karyn his girlfriend and now Erika was Keith's girlfriend. The stone adjusted the sexuality of both Karyn and Erika to fulfill Keith's wish. Now, Erika is bi-sexual and Karyn is a lesbian. And even though Keith is now Erika's boyfriend, Karyn is still Erika's girlfriend. At the same time.
But at the moment, Keith hadn't realized this yet.
