Devil's POV
I'm pretty certain Rick Sanchez has discovered my little spell by now. I wish I could have seen the look on his face when his grandson- excuse me, his granddaughter greeted him this morning. I think this was a very fun way to get revenge on Sanchez for destroying my business, then attacking me, along with that little bitch Summer. I'll get revenge on her later.
Some people may question why I didn't just kill Sanchez. It's because that isn't nearly as fun as screwing with that bastard. Turning his grandson into a girl may seem like a small change, but I know that this one small change will change everything just enough to throw Sanchez off, but still be subtle enough that it won't be obvious what he needs to do differently. It will drive him insane! Which is far more entertaining than just ending his pathetic life. I have no doubt he will come after me, but I don't care. I purposely made this a spell I cannot undo, so even if he attacks me, he is stuck with his new granddaughter.
Rick's POV
It's not that hard to track that dumb Devil down. He's still staying at his old storefront. How predictable. I walk in and find him waiting for me. "Alright you freak," I snap, pulling out my ray gun. "Undo whatever you did to Morty."
The freak smirks at me. "And why would I do that? It would be so much more fun to watch you fumbling to adapt to your grandson's recent change."
He's right, it would be hard to adapt to this. Morty's gender may be the only thing the spell changed, but just the fact that Jessica's a girl will change enough to make it difficult. I mean, just look at this morning. The kid thought I was pissed at her, and all I did was shorten her name. Who knows what else is different? That's why I have to make this creep turn her back. "You're going to do it so I don't blow your brains out!"
The Devil just laughs. Damn, this can't be good. "I can't. When I cast that spell, I specifically made certain that no magical force can reverse it, not even my own. Of course, I'm sure you could figure it out with your precious science, but that would require a great many tests, many of which I'm sure would be painful to your dear granddaughter. And you wouldn't want to hurt her, now would you?"
Shit! If his magic can't undo it, then the only science could help would be to completely restructure Jessica's DNA, which would definitely hurt her, and possibly kill her. I can't risk it, no matter how much I want my old Morty back. "You son of a bitch!" I quickly aim my ray gun and shoot him. I know I only destroyed his physical body, and he IS the Devil, so he can come back, but I don't care. That felt really good.
