24 Nostalgia

Max Tennyson shook his head at the two tiny figures in front of him. One of them was familiar, the other not so. The short girl glaring up at him with green eyes almost too big for her face was clearly his granddaughter, as she had been five years ago at eleven. She'd often glared at him like that during her second year wearing the Omnitrix, up until she lost Feedback. She had gotten slightly cocky during that year though all that confidence had been lost with the loss of that transformation.

"This isn't funny!" She squeaked as Cooper let out a muffled laugh, Pierce had buried his head in his arms, laughing loudly as the Plumbers around them managed to subdue chuckles. Rook, small like her but still a few inches taller, nodded next to her. He seemed to keep a bit behind her though, as if he was a bit scared of what was happening. Max nodded.

"No it's really not, I've dealt with a ten year old Omnitrix wielder before it's not always fun." She pouted at him

"First I'm eleven! Second I wasn't that bad!" Max frowned.

"Don't you mean aren't that bad?" She shook her head, waving her hand, the Omnitrix had shrunk with her but remained the one Azmuth had given her not too long ago.

"Not time travel this time. Still sixteen up here." She tapped the side of her head. "Just not physically, you can blame Billy Billions for this by the way." Max nodded and held out his hand.

"Ok come on, let's get you down to the lab, find out what's going on." Jen nodded, grabbed Rook by the hand and took off towards the lab, Max quick to follow. He huffed. "Oh I'm getting too old for this." Cooper held back a laugh at that too as he followed the Magister and the two children.

Jen frowned at the door. Max and a few other plumbers were going to see if they could get the de-aging gun from Billy, claiming the two now young teens would be safer staying behind. She turned to Rook.

"You coming?" He frowned.

"How do you intend to leave? The door is locked and I do not have my badge, nor will it respond to vocal commands from either of us." Jen grinned and selected Goop on the Omnitrix. It was weird seeing her aliens that she hadn't had when she was younger, they too were now more children than adolescents. But melting through the door was as easy as it always was. She and Rook took off for Billions tower. The fight there, with both Billy and the Dimension Twelve robots, ended with Rook and Jen finally getting their hands back on the de-aging gun.

"You ready to say goodbye to that tail?" Jen teased and Rook smiled.

"I do not know, I have just grown used to it again." His tail smacked him in the face and he frowned. "I am over it." Jen doubled over with laughter. When she finally collected herself she fiddled with the settings on the gun and aimed it, blasting Rook back to his regular age. She tossed him the gun and he shot her with it too, returning her to her proper age. She ran hands through her short hair and smiled. They collected Billy Billions and went to meet the Plumbers gathering outside.

"I am quite curious as to why you decided to cut your hair short. It seems that Earth fashion is quite varied, unlike the more traditional fashion of Revonnah but I see few females with hair as short as yours." She nodded.

"It's more practicality than fashion. I got dragged around by my hair a few too many times, back when I first got the Omnitrix. It became a problem in fights, so I got it cut off. Much more low maintenance and can't be used against me this way." Rook nodded.

"That is a very practical reason." They were accosted by Plumbers and Press when they got outside so it took a bit for Jen to corner Cooper. She had an idea that maybe they could help get Billy Billions back to his proper age too but she'd need help getting it to work.
