A/N: Hey guys! Sorry I haven't updated in a while! Thank you so much for the reviews! Hope you like this chapter!
"So, you guys know what to do, right?" Jenny asked, sitting back on her heels on the couch. The three kids had spent the last half hour explaining to the parallel versions of their parents how to act like them. They had also managed to convince Kevin to change his outfit so that he bore more of a resemblance to the younger boy than his real self. He was now wearing black skinny jeans and a grey hoodie, just like Devlin. Of course, Devlin was now grounded for however long it took him to repair the remote. Devlin had grumbled and almost broken down, but one look from Jenny had that taken care of. Kenny had snickered and gotten himself in another duct-tape related mess.
"Why is that boy so obsessed with duct tape?" Gwen asked, frowning at the two ten year olds.
"He's Kevin Levin's son," Jenny explained, shrugging her small shoulders, "What do you expect?"
Out of the three kids, Jenny was the one who was the least bit bothered by the fact that her uncle's arch enemy was in their house. Even if he was just a parallel version.
"You're not him," she had said, "You're an ultimately better version that just loves to make out with my mom a lot."
"You have no idea," Ben grumbled, immediately receiving a thump on the back of the head from his anodite cousin.
Back in the present, the three kids were sitting on one of the couches in the gigantic living room that could've fit Gwen's entire house in it. Three of them, in fact. Jenny was sitting in between her second cousin and her 'future boyfriend'. Ben lay sprawled out across another couch, looking almost like he was asleep. Gwen sat on the arm of the chair Kevin had occupied. They were quietly sipping smoothies, waiting for someone to finally get home. (Jenny had said that her favorite was strawberry, like Gwen's, Kenny never tried anything twice, which was just fine by Ben, and Devlin hated smoothies altogether. Hearing this, the osmosian had almost begun to cry.)
"Yeah, we know," Gwen told her.
"And, Kevin?" Jenny added, "Try not to kill my dad."
The 17-year-old rolled his eyes at the 10-year-old red head.
"I'll do my best," he agreed.
"It's a good thing Gwendolyn's not gonna be here," Kenny muttered.
"Your sister?" Devlin asked, his eyebrows rising, "Why not?"
"Wait, you have a sister?" Ben asked, opening his green eyes to stare at the boy in surprise.
"Yeah," Kenny said ruefully, "She's older than me so she thinks she can do whatever she wants."
"And her name's Gwen?" Kevin asked, his eyebrow's rising just like his parallel son's had two moments ago.
"Gwendolyn," Jenny corrected him, "She likes it better that way. It's so that no one gets messed up when calling my mom and her."
"Boy, she sounds more annoying than Gwen used to be," Ben laughed. His cousin glared at him and muttered a spell under her breath. The ceiling chipped and a large block started falling onto the young hero. He gasped and rolled off the couch, just as the cement crashed down on it.
Everyone was laughing.
"Hey!" Ben snapped, glaring at his cousin, "Not funny Gwen!"
"Rule number 1, kids," Kevin laughed, "Never mess with anodites."
Gwen smiled and reversed the spell. Once the block was back in place, a wave of nausea overtook her. She felt the room spinning and closed her eyes, leaning back against the armrest. Kevin's arms enveloped her and he pulled her into his lap effortlessly, letting her bury her head in the crook of his neck.
"You okay?" he breathed, rubbing soothing circles into her back.
"I'm fine," the girl said, her voice muffled against his neck. The teen shuddered as he felt her lips moving against his skin. It wasn't hard to forget where they were, or that they weren't the only people in the room. It would've been so easy to just readjust her and meet her lips in a searing kiss-
He was interrupted by the brunette 10-year-old laughing.
"Who knew Kevin Levin was such a sap?" he asked no one in particular.
"Everyone in our universe," Ben told him, sitting back on the couch, "So, what were you saying about Gwendolyn?"
"Oh, yeah," Kenny said, quickly forgetting about the parallel version of his father's cousin and her osmosian boyfriend, "She's gone to her friend's house for the summer, but if she were here, she'd ask way too many questions and in the end someone would spill everything to her."
Jenny suddenly had a fake coughing fit.
"*cough* you *cough*" she said, making Devlin laugh at his friend's murderous glare.
"Wouldn't it be easier to just tell her?" Gwen asked, turning her head to look at the brunette boy, completely ignoring her daughter's slightly juvenile behavior, "I mean, if she were here. We're only gonna be disguising ourselves for the party. Why not eliminate every possible chance there is of it not working?"
"Because," said Devlin, "she'd tell." His voice suggested that it was completely obvious and the teens were stupid for not realizing it.
"She might not," Jenny disagreed, frowning at him, "She'd probably figure out a way to use this to her advantage. Probably to blackmail you, doofus." Her pale, slim hand was pointing at her cousin.
"How do you know that, dweeb?" Kenny snapped back at her.
"Mom says she's like her mother," Jenny answered simply.
"You don't like Kai very much, do you?" Ben asked his cousin, a small smile playing on his mouth.
"Only as much as I like Jennifer Nocturne," Gwen stated. Kevin chuckled, his whole body vibrating underneath her. The girl was suddenly very aware of how close they were. She turned her head to see his now midnight blue eyes boring into hers. The girl was suddenly hyper-aware of him. His hand supporting her back, rubbing soothing circles through the oh-so-thin material of her red shirt, his other hand lying across her stomach, holding her close to him, the way she was pressed against him and how her skin seemed to burn wherever he touched her, even through the material of their clothes, and the way there seemed to be an arctic wind blowing wherever he wasn't.
"How come?" the teen asked, bringing the red head out of her thoughts.
"Ben used to have a crush on her and then she broke his heart," Gwen explained.
"And this concerns you how?" Kevin asked, now genuinely confused.
"When we met her, Ben almost turned into a werewolf, and when we found out that he wasn't one she said that she would've gone out with him, but only because she had wanted to train him… as a dog," Gwen explained, her emerald green eyes now sparkling with amusement.
Kevin was now laughing his head off.
"No wonder you married her," he said to his best friend, trying to contain his laughter.
Ben glared at his friend. The other three stared at the teens. This information was obviously completely new to them.
"Mom just said that Kai was a user with a mind so conniving that it could rival Kevin 11's," Jenny said, frowning slightly.
"Hey!" Kenny snapped, "Don't talk about my mom like that!"
"Right," said Jenny, obviously having just realized that the woman's son was in the room "Sorry."
"Are you sure you're Gwen's daughter?" Ben asked, his eyes narrowed at the girl.
Jenny rolled her ice blue eyes.
"Positive," she stated, flipping her hair back.
Suddenly, they heard a sound like a door opening and quick steps running down one of the thousand's of hallways in Ben's mansion.
"Who's that?" Jenny asked, frowning at the direction the sound was coming from.
"It sounds like-" Kenny cut himself off, growling in the back of his throat.
Devlin snorted.
"Speak of the devil," he muttered.
Jenny shot him a surprised look. Devlin's eyes suddenly turned innocent and he shrugged his shoulders.
"Dad's favorite saying," he explained. Jenny's eyes widened but she kept quiet nonetheless.
The steps were getting closer. Everyone was on high alert, waiting for the person to get to the room. Gwen had gotten out of the chair, much to Kevin's disappointment, and stood beside the chair, her hands glowing with manna. Ben got up to a sitting position on the couch. The door slowly opened and in walked a 13-year-old Native American girl with black hair pulled back into a ponytail and wearing a bright blue dress with a white collar that clung to her skin.
"Gwendolyn?" Kenny exclaimed in greeting, "What are you doing here?"
"Hi, Kenny," she said, rolling her dark eyes, "Nice to see you, too. Is this our new adopted brother? Hi, Jenny."
"Hey, Gwendolyn," the 10-year-old red head said, smiling at the girl with fake enthusiasm, "What brings you here?"
"Your mom and dad's anniversary," Gwendolyn answered. Her eyes suddenly landed on the three teens. "Who are they? Kenny? What did you do?"
"I didn't do anything!" the boy snapped, sulking and crossing his arms on his chest, "Why does everyone just assume it was me?"
"Because it usually is?" Devlin suggested, a small smile on his lips. Jenny smiled.
"It was our fault, actually," Ben cut in, "Jenny's dad pissed off Devlin and he brought us back to this time so he could mess with the guy."
"Wait, so you guys are…?" she trailed off, her eyes scanning all three teens.
"Jenny Goldsmith, Devlin Levin, and Kenny Tennyson," Gwen said, smiling at the girl, "Only as teenagers."
"And quit making stuff up, Tennyson," Kevin snapped at Ben, "You know full well that it's your fault we're here."
"Seriously," Jenny spoke up, glaring at the parallel version of her uncle disguised as her second cousin, "You should've just covered for them."
"Hey, it's not my fault!" Ben cried defensively.
"Yes, Kenny, it is," said Gwen, her forehead braced against her hand.
"What did I miss?" Gwendolyn asked, sitting down on yet another comfy chair.
"Apparently Devlin's going out with Jenny in the future," Kenny said, slapping the heel of his hand against his forehead, knowing that somehow someone would find a way to blame this all on him.
"What?" Gwendolyn exclaimed, "Gwen Tennyson's perfect daughter who never does anything wrong is dating the son of the most evil man in the universe? How is that possible?"
"You really are Kai Green's daughter, aren't you?" Gwen grumbled, sitting back on the armrest of her boyfriend's chair. Kevin rolled his eyes and wrapped an arm around her, pulling the girl back into his lap.
"Yes…?" said Gwendolyn, frowning at the girl, "Jenny, your parents are gonna freak!"
"Her dad will," Kevin corrected her, a slightly smug smile on his face.
"Most of us haven't even met Devlin Levin as a kid, let alone a teenager who's dating Ben 10,000's goddaughter," Gwendolyn reminded him. Her eyes were narrowed at the teen. "So you might want to tone the whole relationship thing down a bit."
Kevin chuckled.
"No chance in hell, princess," he stated. Gwen rolled her eyes.
"Actually she has a point," Jenny spoke up, "Almost no one knows that the Tennysons have adopted Kevin Levin's son."
"Jenny?" Devlin, who had been surprisingly quiet throughout this whole thing, suddenly spoke up, "I really don't think people are gonna be too big on the idea that the son of the guy who almost destroyed their city is living here."
"Didn't I already tell you?" Jenny asked, glaring at the boy, "You're his son, not him."
"You're gonna have to tell him that at least 50,000 more times," said Gwen, smirking at the girl.
"And then 50000 after that," Ben added.
"Shut it, Tennyson," Kevin said, smirking at his best friend.
"Anyway," said Devlin, growing slightly impatient with the whole thing, "Is there anything else you want to know?" He turned to look at Gwendolyn.
"Yes, actually," said Gwendolyn, suddenly reaching in her bag and pulling out two boxes, "I'm sorta glad that you three are here. Jenny, which one's your mom gonna like better? This one, or that one?"
Gwen frowned and got out of Kevin's lap, walking over to the girl and the two boxes.
"What are they?" she asked, frowning at them. Jenny held her breath and Devlin and Kenny hit their foreheads with the heels of their hands. The two boxes turned into different coffeemakers. Everyone from this generation – no, this universe! – knew that! Gwendolyn stared at the older version of her cousin with a weird look on her face.
"Are you sure traveling through time didn't mess with your head?" she asked, frowning at her, "Or is some of Devlin's stupidity and forgetfulness rubbing off on you?"
"Dude, I hate your sister," Devlin announced, glaring at the Native American.
"Join the club," Kenny muttered.
"How did Dad ever come to adopt you?" Gwendolyn snapped at the dark haired boy, jumping out of the chair.
"How did he not adopt you?" Devlin shot back, his demeanor was calm and relaxed. The parallel version of his father was very proud of him.
"Ugh, I am going to my room," Gwendolyn snapped, taking the boxes with her and disappearing through the door.
As soon as she was gone Kenny started laughing.
"Nice one," he choked out, bumping his fist with Devlin's.
There was a smug smile on Devlin's face. It took him a moment to realize that Jenny was glaring at him.
"What?" he asked, his eyes widening as he took in the red head's hostile expression.
"Was that really necessary?" she asked, crossing her arms on her chest.
"Hey, it was either that or ruin the plan," the boy said, holding up his hands in surrender.
"Kevin?" Gwen's voice suddenly interrupted their discussion, "Are you crying?"
The room seemed to freeze as everyone turned around to look at the dark teen. He was indeed sobbing!
"I have never…been…so proud…in my entire life," he finally got out.
Ben, Jenny and Kenny exchanged amused smiles as Gwen walked over to her boyfriend and wrapped her arms around him, letting him pull her into his lap so that she was straddling him.
Devlin's eyes bore no trace of amusement. The boy was purely shocked. His father never cried. This was a rule. No matter what time period, or what dimension, Kevin Levin didn't cry. Yet he was seeing proof that this was not true.
"Are you okay?" Jenny asked, smiling at the boy lightly, still not over the whole the-most-dangerous-man-in-the-universe-is-crying-right-in-front-of-us thing.
"Yeah, fine," he assured her.
The girl put her hand over his and smiled at the boy. This time the smile was warmer, like she was genuinely concerned.
"You sure?" she asked, her innocent blue eyes sparkling.
"Yeah, I'm sure," he said, feeling a smile of his own appear on his face.
"Ugh, guys!" Kenny suddenly yelled, "Save it for when they get here!"
The two kids turned around to see Gwen's hands in Kevin's hair, his arms wrapped tightly around her waist, their mouths connected. The two were in the middle of one of their heavy make out sessions that no one, no matter how dangerous and/or important could interrupt. And if by some miracle they did manage to interrupt it, then they would've had to deal with the wrath of Gwen Tennyson and Kevin Levin. People in Bellwood had learned not to interrupt the two teens, no matter where they were. And if they by some crazy accident did, it was better to run and take cover and let the two resume what they had been up to just two seconds ago than push it.
"Forget it," said Ben, grimacing at the two teens, "They've made out in front of Grandpa Max, her parents, and almost all the rest of Bellwood."
"Great Grandpa Max?" Kenny repeated, his emerald eyes widening in shock.
"Yeah," said Ben ruefully, "Twice."
"Okay…" said Jenny, her face growing paler.
Suddenly they heard the door opening again. The three kids and teen heard the sound of voices in the hall, all of them immediately freezing.
The door slowly opened to reveal-
"WHAT THE HECK IS GOING ON HERE!" Ben 10,000 yelled, seeing a teenage version of his goddaughter in the teenage version of his adopted son's lap.
