- CHAPTER 12 - "Screams"

Cindy was still screaming at the thought that she would be dating a chubby nerd guy but with good behaviour. She stopped at the thought. She smiled at that. The good behaviour. Kind, cute, sofisticated nerd guy. Next time she would be more like him. Wait! A next time? It was her decision... But thought something was wrong... He didn't even knew how to treat girls. All he was talking about all the time was about llamas. But today, he looked really sincere and kind.He reminded her of someone...

"Hey, Cindy!" Jimmy said, as he started to walk upstairs to his room, happily.

She had never saw him waving, neither speaking to her lately. This was suspicious. "Ok! Stop! What's the big deal?" she asked.

Jimmy stopped dead in his tracks. "Huh? What's wrong?" he asked.

"Little brother, I know that we don't speak much lately, and I know that we hate each other more than hell, but I had a date with Carl, your friend and because of the way he was acting and the way he was treating me, I figured it all out. It's all your fault!" she said, as she pointed at him.

"What? W-what are you talking about?" Jimmy asked, grining and nervously looking at each side finding a way to escape. "Do you think I just d-dressed Carl like that and told him how to act?".

"Exactly" Cindy said, as she crossed her arms over her chest.

"T-that's ridiculous! You... you have no proof of that!" Jimmy said, more nervous as he pointed an acussatory finger on her.

Suddenly, the door bell rang. Cindy opened the door to find Sheen standing at the porch, dressed with a black tux and the same mostachoe that Carl wore the night before.

"Pardone moi, mon cherie" Sheen said. "You look beau-".

She slammed violently the door on his nose and turned to look at Jimmy with a glare, but there was a blank space at the stairs. Jimmy took the opportunity to sneak and run away. She stomped through the stairs and when she reached his room, she found Goddard standing in front of her. She could sense he was glaring at her to protect his brother.

"Where is he?" she asked, fiercely.

Goddard shook his mechanical head in response. But shrieked when he saw that Cindy suddenly showed him from nowhere a screwdriver.

"Tell me, or suffer the consequences" she said, grinning evily.

He had no choice to reveal the truth. He walked a few steps to show that Jimmy was hiding in his closet. She opened the door and all that Jimmy could say was a "Man's best friend!", until he was pulled from his shirt.

----

Two hours later, Jimmy woke upfrom his bed with a dark eye and his head hurting real bad. He ran to the bathroom to reveal the state of his face. He suddenly frowned.

"Enough!" he shouted. "I'm tired of her! I'm tired of being his brother! This has got to stop in some way!" he said, as he jumped from his bed.

He walked to a poster on the wall and moved it a little, revealing a tube to go down his lab. He jumped in and landed on the floor. He walked a few steps to his computer and took a seat on his couch.

'Ok, all I have to do is to test ifis she really my sister. I have toinvent something that would take a single drop of her blood without her knowing it' he thought to himself. 'And the answer is... a mosquito'.
