He brags about the script and what it does

Chris flaps the papers he was previously scribbling in in front of her face. Kirsty was able to see the front of it, and read in an almost illegible calligrapher's strokes, "The World part-" and followed by a character that looks like a mass of moving squiggles.

"Well you see, dear twin of mine," Chris says to her mockingly, "I have found something splendid! This appears to be the script to all of our reality, and everything that's happened, happening, and going to happen is written in here. And from some light experimentation, found that the script can alter itself depending on any amendments made within the script, making retcons seem normal unless said otherwise." He tapped the back of the book with the butt of his red pen, "The only limit it says in the index portion in the back that it needs to be done in a red ink, any other color is unpredictable on what would happen." But Kirsty looks up at him confusedly, thinking that he may be delusional, still though, she did give herself an involuntary wedgie...

Chris went back to the script and flipped a few pages around, and frowning at something. "So you don't believe me, huh? Well, I understand that," And flips the pen around again to start writing. "I figured you might need proof, so I'll let you know of this change this time." Kirsty was annoyed, and was in the process of standing up when suddenly, she felt a weird shifting on her head. She reached up to feel a massive pink afro taking place of her old hair, as if somebody took a large round sponge the size of a beach ball and glued it around her head. Kirsty screamed, holding the mass that was her new hair with both hands, disbelieving it actually happened. Kirsty looks towards her brother, leaning back in his swivel chair, once again annoyingly tapping the cheap 10-for-$3 pen against the open script. Kirsty was on alert now, she now believed in the power that the script held, the wedgie was skeptical, but the afro was enough to make her pale skin even paler on what her brother; Which she openly hated for a long time, has over her life.

"Now bro, Buttslut knows we weren't exactly the best of...family..." Kirsty says steadily, trying to pick out her words carefully to avoid being hit by any further revisions, "But now Buttslut has more respect for you. You were able to figure out how that thing works, after all, so maybe we could...Join forces...yeah, like Buttslut help you by giving you some ideas, and we could have some fun out of other's expense!" And away from my expense she internally reasoned, hoping that her thoughts aren't included on the page that Chris was on.

Chris made a face as if pondering, humming in almost mock-thinking tones. He looked at Kirsty, sneering then turned into a lecherous smirk. This made Kirsty feel almost queazy, and something else; something like a light warming sensation in her face, working down her body like a slow creeping heat. "Well, I'm going to see something for a hot second..." Chris says as he holds up his finger, as if telling her to wait. He looks down at the script, pen tucked in his held up hand.

In a quick second, Kirsty's strategic side told her that this was the perfect time to lunge at him, take the script for herself, and stop whatever he's planning. But another, smaller voice was telling her to wait, and see what happens, almost telling her that she may want to be changed again...
