"I wish I knew what was going on here."
Wait a minute, Jenny was a guy? And Jon changed Biff to a girl, and Gary changed Jon to a girl for revenge, and Biff just changed back because of the marriage?
Karyn liked Gary, because he was her friend's father-in-law, but this was unreal. The whole thing was fake. Karyn didn't even know him. Jenny wasn't married to Biff until a few minutes ago, and Karyn only thought otherwise because Gary had wished that everyone remember Biff as Biff, and they remembered the new reality.
But Karyn also understood that it wasn't really anyone's fault. It was bad for Jon to change Biff into a girl, but that was a desperate wish made in self-defense, and the wish that Biff remember being a girl wasn't Jon's, it was an accidental wish from Biff himself. The wish that everyone else remember Biff as a girl was Jon's, but that wish had no effect, since the wishes affect people's memories anyway. And Karyn herself had agreed with what Jon had done, so the part that was Jon's fault was her fault too.
And it was also bad for Gary to take revenge, but now that Biff was back, Gary no longer wanted revenge, and the marriage wasn't part of that revenge, it was just an accident.
Even Gary's wish on Karyn was just something Gary made to get out of a tight situation, and the tight situation wasn't his fault. After all, he was trying to get the stone in order to restore Biff and not be thought crazy, and he did have a right to do that. And since Karyn had free choice, she didn't have to stay Gary's friend if she didn't want to, any more than wishing for long hair means the hair can't be cut.
So, in the end, Karyn decided not to strangle Gary.
Still, maybe she could help a little bit. She thought out her wishes and finally made them.
First, make Jenny not be a bimbo. "I wish that Jenny is a bimbo because acting that way was a way to get along with other cheerleaders who are dumb, but that since she's only a bimbo because she's acting, she's a normal person at other times." Karyn decided that it was okay to keep Jenny hot and sexy, though.
Next, make Jenny more like Jon. The problem was that Gary had wished that Jon was mentally Jenny and that he forget being Jon. So she couldn't fix most of it. "I wish that without a change in Jenny's mentality, she remembers the things that Jon remembers, and that while she doesn't actually remember that she was Jon, having Jon's memories lets her instantly figure that out."
Now, Jon and Biff. "I wish that Biff remembers everything that happened, but that he still loves Jenny, keeps the mentality he has now, and is really sorry for trying to beat up Jon."
Which was all the fixing that Karyn dared do now. Maybe sometime she could fix the sex change and the marriage. But for now, Jenny had brains, she and Biff both remembered their old lives, but they were still married and had the minds of lovers.
Meanwhile, Jenny and Biff had gone off, and now they....
