Kat had been crying for a good 40 minutes, and by now, had completely broken down all of her former stubbornness and pride. All that was left was her "true" self. Save for the part where she was hopelessly infatuated with her brother's pussy. Her self reflection had unveiled just how large her ego and superiority complex had grown. Sure Dan was a complete ass sometimes, but so was she, and she also didn't have to take it this far.
She felt that she had definitely crossed a line this time. Getting revenge was one thing, but raping, impregnating, and forcing your brother to lay eggs and lactate continuously while pregnant was extremely overkill. And furthermore, she had tried to rape him again when he came begging for her help. Not only that, she even made Dan body find his siblings so attractive that he couldn't help but think about having sex with them.
Kat was certain that Dan hated her. She already hated herself enough. She had used magic vs someone who could never even hope to retaliate, and that person being her own brother only made her feel worse. She had to apologize and make it right, or at least try and end their back and fourth cycle of revenge.
After gathering up what little courage she could muster, Kat left her room, and made her way to Dan's bathroom door, where she knocked. "Dan, I am so sorry. I took things way too far, and it wasn't right of me to use magic against you like this. Can I please come in? I want to say this to your face." Kat heard a click from the door as Dan unlocked it from the inside. Kat was happy she was abke to properly apologize to Dan, however what she saw after entering the bathroom was so far beyond her belief that she became completely speechless.
