Author's Note: I'm fairly certain there are other one-shots I haven't uploaded of this series, so I'm gonna post as many as I can find today. I hope you enjoy. This idea and its spinoffs are probably my favorites.

Just Dance

He attended a school function in disguise. All day, he'd been divided, having tremendous headaches between what the voice dictated and the memories it barely held at bay. The voice didn't think attending a Retroville dance was a good idea. Jimmy was fresh out of ideas and needed to escape the mansion before his patience ran out completely and he did something he'd regret. Goddard had already been electrocuted twice today.

His thought patterns weren't particularly clear, however, and he found himself sitting alone with a pounding headache. The Wizard had altered his hair to blonde and his eyes to charming, mesmerizing silver. He'd shrunken his head so it wasn't as noticeable, and he couldn't concentrate on songs because the pounding headache drove away all conscious thought. He didn't know what he was doing here, torturing himself. The voice didn't have any bright ideas, but the voice was gargled at the moment. Jimmy groaned, resting his head in his hands and hoping someone might come along with a shot gun and put him out of his misery.

"The music's not that bad," Libby scoffed and Jimmy stared up at her. She wore a red dress that clung to her curves, which were much more refined at age thirteen than they had been the last time they had met. Her ample chest was wrapped up in a dress that ended at her ankles; the dress had slits along the side and two spaghetti straps. In addition to it, she had her hair combed out and pushed back with a tiara with a single ruby set inside.

Jimmy didn't respond. He had a moment of mental panic- the Wizard hadn't aged him, so his voice sounded the same. It might be recognizable, if nothing else was.

"Who's the new kid?" Cindy asked and Jimmy's heart clenched.

Ignore her. Ignore her. Ignore her.

"I don't know," Libby replied. "I've never seen him here before. Ugh...where did Sheen go this time?"

"He's kinda cute," Cindy said. "You go find Sheen and I'll talk to him."

Libby didn't need to be told twice. Scoffing and muttering about incompetent dates, Libby stormed off in red flats. Cindy pulled up a chair and stared at Jimmy. Jimmy's headache redoubled. His eyes were watering from the pain and he groped ineffectually for his cymbals. The last time he'd had a headache like this was when...

The voice tried to block, it didn't quite work, and Jimmy gasped, inundated with an image of Jet Fusion slamming his fist repeatedly into Jimmy's head. Chills broke out along his body and the Retroville Junior High school auditorium/gym/ lunch room swam before his eyes. Cindy snapped her fingers in front of him and he looked up at her. She frowned at him.

"If it's that bad, why don't you call your parents and ask to leave?" she asked. She had no sympathy for him, even without realizing it was her old rival.

"My parents don't know I'm here," he said in a voice made husky by the terrible pain threatening to split his head in two. And good riddance, the voice added. He had another visceral recollection of Beautiful Gorgeous wrenching his arm behind his back and Eddie punching him in the gut. It was enough to make him shudder and his teeth chatter.

"You left without telling them?" she said. "You needed permission to attend this dance." She gave him a shrewd look.

"Not if you crash it," he said with a faint smile.

"I'm calling your parents," she said and rose to her feet. Then she halted. "Once you tell me who you are."

Jimmy inhaled shakily and tried to compose himself. "I don't live around here. Not anymore."

" 'Anymore'..." she said. "I've never seen you before in my life."

Jimmy laughed hollowly. "I expect you haven't, Vortex."

Cindy stiffened and stared hard at him. He could tell she was slowly beginning to cotton on, not that he was Jimmy Neutron, but that something was amiss. Her eyes narrowed and she put her hands on her hips. Libby hadn't tracked Sheen yet and none of the other party goers were yet privy to this scene.

"How do you know my last name?" she said.

"You're legendary," he said. The voice had approved of this game a while back. It was always entertaining to bait Cindy Vortex. "You're the smartest girl in your class."

"But the way you said it..." she stopped herself and shook her head. "Never mind. I am the smartest girl in my class, but I wasn't always." Her expression darkened. "That honor used to belong to Neutron, before he went insane for no reason and abandoned us all."

A cold, maleficent rage seized Jimmy and he glowered at her. "There was a reason."

Startled, Cindy blinked at him. "What do you mean? How would you know? Who the hell are you?"

Jimmy's headache brought more tears to his eyes and he gasped, unable to maintain eye contact. The voice wanted him to retreat. Jimmy's memories were held at bay by a single tiny thread Jimmy felt certain was going to snap, and he wasn't sure whether he cared or not if Cindy knew his true identity. All in all, the night was going to hell in a hand basket and he'd only been in Retroville for a half hour. It was a new record low.

"Convenient," Cindy snarled. She lifted his head and peered into his eyes. The voice wanted her to release him. Jimmy was in too much pain to protest vehemently.

"You seem so familiar," she said. "And you still haven't told me your name. And your voice..."

"Hey, Cindy!" Sheen called and bounded up to the table. "Hey, Jimmy!"

Jimmy froze. Even the voice did a double take. His headache seemed to lessen by a small degree, so he could stare at Sheen, which Carl, Cindy, and Libby were now doing in spades.

"...What are you talking about?" Cindy said.

"That's not Jimmy," Libby said.

"Sorry," Sheen said, grinning from ear to ear. "Force of habit. Though he does have something very Jimmy-esque about him. Make his head bigger, change his hair and his eyes, and it's definitely him."

"You're delusional," Libby told him.

Cindy wasn't so quick to dismiss it. She appraised Jimmy and whispered, "Neutron?"

"No," he said. "I am not. My name is Robert Provanzano and I'd thank you to remove your hand from my hair." He scoffed and pulled back. She glared and he glared back.

"What brings you here, Robert?" Libby asked.

"Nothing," Jimmy said, now gloomy and growing increasingly concerned Sheen had actually seen through the disguise and was being nonchalant about it. He wouldn't put it past him. Sheen could be awfully keen when he wanted to be. He rose to his feet and Sheen stared at him. Jimmy switched his gaze from Cindy to Sheen and saw the spark of recognition. Sheen knew. Jimmy didn't know how, but he knew.

"I have a headache," he said, which, at least, was the truth. "I think I will in fact call my parents and ask for a ride home."

He headed for the bathrooms to use the phone booth and his heart hammered in his chest. The voice was calling him a fool, an idiot desiring a cheap gimmick, and Jimmy couldn't fault it. He stumbled out of the gymnasium and Cindy followed him at a distance. It didn't matter if the gimmick was up. He had no intention of transporting her too.

"Who are you really?" Cindy said.

"And why does it matter to you?" Jimmy answered. "What difference does it make if I'm James Provanzano, Robert Provanzano...or Jimmy Neutron?"

Cindy started. "You are...!"

"I never said that," he said and smiled benignly. "You did."

He clipped the cymbals on his index and thumb. "Good night, Cindy."

She lunged and he stepped aside. Her hands found his collar and she shoved him against the wall. In such close proximity, he'd never be able to transport without bringing her with him. Hissing in irritation, he did what the voice bade and smacked her in the face. The blow was enough to stun her, but her hands were still stuck in his shirt. He pushed her and she released him, mouth agape.

"Tell me," she said. "Tell me!"

"Jimmy Neutron," he said with a small, very sad smile. In the fraction of a second it took for her to process this, he clipped the cymbals together and vanished. He heard, from a distance, her bestial scream of loss and anger. It sent his heart skittering and the voice told him to ignore it. He did, with a heavier heart than usual. The voice was right. This evening had been a mistake.
