"So, you guys check out the new UltraLord movie?" Sheen asked as he wrapped his arms around Libby.

"No!" his four friends shouted at once.

Carl, Sheen, Libby, Jimmy, and Cindy were hanging out at a stairwell before school started. They had a good twenty minutes before the warning bell rang.

"Man, it's great that we're all hanging out again, isn't it?" Cindy asked as held Jimmy's hand.

"Yeah, why did we drift apart?" Carl asked as he cleaned his glasses.

"Because Jimmy became a hermit," Sheen said. The girls stared at Carl and Sheen.

"It's fine, we can talk about it," Jimmy said. The gang still felt nervous whenever they talked about Jimmy's strange behavior. "I just had some, uh, issues. I'm just glad we're all friends again," he happily told them as he gave Cindy a quick kiss.

"Hey Neutron," John spat as he leaned against the wall opposite the five friends.

"John," Jimmy quietly said as he tightened his grip on Cindy's hand.

"So, what's new?" John asked as he stared Jimmy in the eyes.

Jimmy let go of Cindy and put his hand to his head. He was getting another headache. "You ok?" Cindy asked.

"Yeah, you need to go the nurse, Jimmy? Can't handle a little headache?" John sneered as he continued staring at Jimmy's eyes.

Jimmy broke the eye contact and hugged Cindy close to him. "Yeah, I'm fine," he muttered.

"So, Cynthia," John continued as he walked over to her, "you want to go out Friday night?"

"What?" Cindy asked, quite surprised.

"You know, like a date?"

"I, I'm dating Jimmy. You know that, right?" she continued.

"Oh, really? You can do a lot better," he told her.

"Alright John, just get the hell out of here," Jimmy angrily told him. He dropped Cindy's hand and clenched his fists.

John stared down at Jimmy's fists. "Why, is little Neutron going to make me?"

"That's it, you're dead!" Jimmy yelled as he ran towards John.

"Ok, calm down you guys," Libby told them as she and Sheen held John back. Cindy grabbed Jimmy's waist and tried to keep him still.

"Look at that, Neutron's not even strong enough to break free of his girlfriend's clutches. And you actually think you can take me?" John teased.

"Let me go," Jimmy whispered as Cindy struggled to hold him back. Cindy stared at her boyfriend's eyes. Boys, she thought as she let him go. Libby and Sheen did the same.

Jimmy ran forward and swung at John's face. John just blocked it and punched Jimmy in the stomach. Focus, Jimmy. Remember your training. Jimmy took a fighting stance and waited for John to attack.

John took a swing at Jimmy's face. Jimmy grabbed his wrist and flipped him. John just went with it and rolled once he hit the ground.

"So, Jimmy thinks he can fight, huh?" John asked as he sent a roundhouse kick to Jimmy's head. Jimmy grabbed a hold of John's leg and twisted it. John just jumped up and rolled in the same direction in mid-air.

Jimmy tried to punch John in the stomach, but John just moved out of each one's way. He then karate chopped Jimmy in the neck as the last punch went by.

Jimmy fell to the ground in pain. He looked up and rolled to the left just as John's foot flew by where his head was. Jimmy jumped up and managed to kick John in the gut.

John just shrugged it off and sent a jab at Jimmy's face. Jimmy ducked and kick-swept John's feet out from under him. As John fell he grabbed Jimmy's collar and threw Jimmy behind him and into a wall.

Anyone else would have blacked out, but Jimmy's training had paid off. He picked himself up and resumed a fighting stance, as did John.

At this point there were hundreds of students crowding around the two teens. They had never seen a fight like this. It looked like Jimmy and John were fighting to the death.

John grabbed a nearby Snapple bottle and smashed it against the wall. The students gasped. John ran up to Jimmy and tried to stab him. Jimmy dodged John's attempts and managed to kick the knife out of John's hand. The crowd wisely took a few steps back.

John and Jimmy continued to exchange several blows. Jimmy couldn't help but take a dew steps back as John continued to throw punches. Soon he was right next to a flight of stairs. John managed to kick Jimmy backward and down the stairs.

Roll, roll, roll, Jimmy thought as he fell down the stairs. He tried to loosen up as he rolled down. He landed on the floor with a smash. Luckily the staircase hadn't been very big.

Someone in the crowd shouted as John jumped down the ten stairs and landed right next to Jimmy. He stood over his and started to punch Jimmy's face. Jimmy tried to block them, but John was too fast. He managed to lift his feet up and kick John off of him.

"Guys, stop this! You're taking it too far!" Cindy shouted from the floor above. The entire crowd was staring down at the two teens.

Jimmy and John continued to fight. John unleashed a torrent of blows, most of which connected with Jimmy. Our hero walked backwards until he was up against a wall. John grabbed Jimmy's hair and smashed Jimmy's head against the wall repeatedly.

Jimmy slowly slid down to the floor, barely conscious. John bent down and whispered something into his ear. "Don't ever fight me again, or I will kill you." John spun around and kicked Jimmy in the face before walking off.
