Now, if you hadn't gotten it by now, the "essense" of whatever was left of Jon inside Amber was now totally gone. And since wishes can't be reversed, it's highly unlikely that Jon will be back.
Amber was now a hot big-breasted sex-crazed bisexual girl. And nothing more.
And right now, she wanted Allison.
"Get away from me, you bimbo," Allison panicked.
But Amber didn't. She reached out and grabbed Allison's chest and squeezed her breasts, through her shirt. Allison pushed Amber's hands off of her. "Steve! A little help here."
Steve was frozen. He just couldn't believe what he was seeing. Amber Starlight! In his house! And she was trying to get it on with his girlfriend. It was almost kind of humorous.
But, his girlfriend wasn't laughing.
