Maddy felt her mind split in half. She grunted in pain, annoyed that this pain started when she wanted fruit. There wasn't much of the original Maddy left. All there was was the most primitive form of her, which, off the record, she was almost like anyway. The pain felt like her brain was deciding to split apart. And, in a way, it sort of did. One side was Maddy, another side started to have a personality of it's own. One that acted more like that primitive side to Maddy. Maddy's IQ went back up a bit more. Not by much but enough to get her back to "normal".
"Oh, god... thank god that stopped. Stupid headache"
"Stupid?" A voice went through her head.
Maddy looked around. Surely it could have been someone else around here that said something.
Nope. No one. Confused people, sure, but they didn't say anything.
"What was that?" she thought.
"Helloooo?" She felt that her mind was knocking against itself.
"Great, not only do I have the headache, I'm now hearing things"
Her arm lifted up without her knowing and started to pick her nose.
"Hey! Why am I doing this?!"
"I wanted something to eat, since you didn't get the fruit!"
Maddy was scared. Deeply, deeply scared. "W-Who's there?"
The voice felt annoyed. "I'm bored of you asking questions. Time for me to take over"
Maddy didn't feel her body move, but she definitely saw it. She tried to speak but her mouth didn't say anything apart from ooks and eeks. "Who are you?"
The voice that was in her mind was in control. That voice was now coming out of her mouth. The voice laughed and grunted. "Me Buttercup. You now monkey now"
