he didn't notice when It started taking him over. the process was slow, as was the change that came along with it. Neither his friends nor his family realized it, either - they were too busy with their own little lives and their own little problems.
Jonas didn't realize the alien had laid its eggs in his head untiol that fateful day when they hatched, and little baby ones started streaming out of numerous holes in his skull. So as to keep him alive as a food source, the alien had already secreted a kind of local anesthetic to keep him from passing out due to pain. Jonas kind of sat there, in the middle of Mr. Watkins' math class, aliens streaming out of his head, trying to figure out what the square root of 64 was.
"eek!" a girl screeched.
"yes! that's right!" Jonas thought to himself. "eight!"
Jonas quickly scribed down the answer.
"eek!" a few other girls screeched. Jonas tried to block it out - the next question probably had a different answer.
"jonas has giant bugs squirming out of his head!" the class bully, Rod, shouted. Rod was always shouting - he was a very shouty kid. Jonas didn't really appreciate how he was making fun of his lice in the middle of a math quiz. it wasn't very polite at all - he'll probably get some points taken off of his test for it, Jonas thought to himself. wondering why Mr. Watkins hadn't called for everyone to quiet down yet, Jonas looked around the room. Mr. Watkins was laying on the floor in front of the room, sleeping. Jonas thought he looked a little pale - he must've been really tired! looking across the room, it seemed as if perhaps everyone else was sleeping, too. about half of the class had the pale-sleeping thing going on. Jonas regretted going to bed early. a dash of jealousy rose in his heart.

"blah blah blah!" the larvae said to each other.
"blah BLAH!" they responded.
