"This is all your fault." Derek yelled from the kitchen at Stiles as he was desperately trying to calm down a very upset 4 year old banshee. A 4 year old banshee that was continuing the banshee scream on supernatural levels.

"How is this my fault?" Stiles claimed from the dining room as he was trying to reach for a 4 year old kanima that had shifted and was now handing from the chandelier by its tail. Lucky for him, this one was laughing and clapping its little hands together.

"Because you have yet to learn how to say no to Lydia and Jackson when it comes to watching their kids. We already had three kids to watch." Derek reminded him, "Plus, you haven't been feeling well."

"I'm well enough not to say no to Lydia." Stiles countered back easily, "Next time you say no to Lydia," Stiles offered to him as he finally was able to grab one of small hands, "Let me know how that works out for you." Stiles doesn't get a response out of Derek, "That's what I thought. Danny sweetheart the chandelier is not a swing set. Get down from there."

"No!" Danny shouted back at him in a high pitched voice.

"Come on, don't you want to go help Uncle Derek with Natalie?" Stiles asked him, even though a part of him was secretly begging that the kid would listen, "She seems very upset."

"Can I keep my tail?"

"Of course you can," Stiles immediately answered, "Now come big guy."

Danny reached for Stiles with his claws still out. Thankfully, Stiles had on shirt that covered his shoulders otherwise he would've been paralyzed for the next two hours.

Once, Stiles had managed to place Danny on the floor, the little Whittemore rushed over to his sister who immediately stopped screaming.

"You cheater!" Natalie yelled at her brother, once she calmed down. The only response she gets out of Danny is that same smirk Jackson had on his face.

"Alright you two, get back into the living with everyone else." Stiles told them. The Whittemore twins made a giggle sound and headed out room.

"Thank God that's over with." Derek commented, but he noticed that Stiles wore a worried expression on his face, "What's wrong?"

"They giggled." Stiles told him.

"So?"

"They giggled, Derek. This was just a distraction." Stiles informed him as he rushed into the living room.

When Stiles and Derek both reached the living room, they only find the Whittemore twins sitting on the couch with smiles on their faces.

"Where are they?" Stiles questioned the duo, "Where are Melissa, Noshiko, and Isaac?"

That's when the lights in the living room suddenly went out, "Noshiko Yukimara-Hale!" Derek claimed, "We have talked about you playing with lights. Turn them back on!"

"Never!" A little voice said into the darkness. Thanks to his enhanced hearing Derek was able to pick up the sound of little feet now running throughout the house.

"I have a real bad feeling about this." Stiles told Derek as they were now trying to focus on their hearing to find three rouge children.

Just as Stiles finished his sentence he heard the sound of a small laugh coming from his right just as an arrow barely missed his face and landed onto Stiles and Derek's wedding photo from four years ago.

"Oops!" A little voice said filling the room

"Melissa!"

"Don't worry Uncle Stiles," Melissa's tiny voice said from what Stiles guessed to be the stairs out from the hall, "It was a plastic one."

"And that makes it okay?" Derek demanded, "Where is Isaac?"

That's when the lights in the house suddenly came back on just as Isaac, who apparently was on the wall, jumped right onto Derek with a mighty, "Roar!"

Completely unprepared by the sudden ambush, Derek goes down with Isaac playfully biting at him as he was suddenly getting piled up on by every child in the house, "Stiles, help me!" Derek cried out in feign distress as the children continued to gang up on him.

Stiles did no such thing as he was too busy laughing as the children overpowered Derek, "Nah, I'm good."

"Traitor!"

"Alright kids," Stiles said once he was done with his laughing fit, "That's enough, I think Uncle Derek needs a break." However, none of the children were listening to him since they were enjoying tormenting Derek, "Let's go have ice cream in the kitchen."

At the mention of ice cream, the pile of kids got off Derek as they now pushed each other to get into the kitchen. Derek turned his attention on Stiles, who was now wearing a smirk on his face.

"You knew." Derek accused him.

"Maybe." Stiles said with a pleased tone, "Don't act like you're not proud of it. I can smell the happiness on you."

It wasn't until later when everyone picked up their respected child from them, "You're kids are a handful." Derek told the members of the McCall-Hale Pack.

"Derek's just mad because he got ambushed by a bunch of 4 year olds." Stiles told them.

"It's nice to know that they are learning how to work together." Lydia commented in a pleased tone as Jackson was trying to get Danny to stop moving his tail around.

"Wait till you guys have your own." Allison told him with a laugh as Scott got all of Melissa's plastic arrows back in the holder.

"Oh no." Derek told them, "We are never having kids." Just like that the group fell into silence and Derek could smell tension in the air, "What?"

"You never want to have kids?" Stiles asked him softly.

"After what we had to deal with this evening with these little monsters-"

"Hey!" All the kids claimed.

"No way in hell." Derek finished.

"Uncle Derek said another swear!" Isaac voiced in a tattle tale tone, while Boyd was trying to get the little werewolf into his jacket.

"Oh okay." Stiles whispered, "I'm going to go…yeah." Stiles mumbled weakly as he walked away from everyone.

There was a moment of silence before Lydia cut the tension, "I can't believe you said that right in front of him."

"Seriously Derek how could you say something so stupid." Laura told her brother while hitting him.

"You need to go fix that man." Scott told him.

"Fix what?" Derek asked because seriously why was he now getting attacked right now.

"Guys, I don't think he knows." Kira told them as she looked at him with a thoughtful expression.

"Know what?"

"Stiles is pregnant you moron." Erica told him.

That's when it suddenly made sense now. Why Stiles had lately been feeling sick and smelling like vomit. Why Stiles agreed to watch everyone kids tonight. It was coming together quickly and he pretty much just denounce their own child right in front of him.

"Shit."

"Ohhhhh….Uncle Derek said another swear." Melissa chimed in a singsongy voice.

"Mommy is this what you mean by Uncle Derek being an idiot?" Noshiko asked Laura.

"That's exactly what I mean." Laura told her even though she could feel the daggers Derek was throwing at her, "Come on guys, let's go."

All the kids ran out the house trying to push each other out the way and left the adults staring at Derek. It was the stare he always got from them when he says the wrong thing around Stiles.

"Yes, I know." Derek told them without anyone having to say anything, "I'm an idiot. Now go away so I can go make up with my husband."
