Adventures in Babysitting

Date nights were incredibly rare in the Barton household. With two kids and a third on the way, missions, and a somewhat working farm to take care of, Clint and Laura had a difficult time finding a spare moment to go out to dinner and a movie. So when Pietro and Wanda volunteered to watch the kids so the Bartons could celebrate their anniversary, Clint and Laura didn't hesitate.

"Just don't burn the house down and everything will be fine," Clint said as he grabbed the keys to the truck.

"And if you need anything, just call us," Laura said, smiling at Wanda.

"We'll be fine," Wanda said. She and Lila were sitting on the floor, looking up nail art online to try out later that evening. Growing up, Wanda hadn't had many chances to goof off and act like a child, so she had never really painted her nails just for fun. It was going to be an experience, especially since most of Lila's nail polishes were glittery or neon.

Clint helped Laura into her jacket and then rubbed her shoulders. This was the first time that just the two of them had gone out since before the Avengers' last mission, so they were both looking forward to the evening. Plus, there was no one more capable of watching the kids than Pietro and Wanda, except for Natasha, of course.

"Yeah, after you're gone, we're just going to start a bonfire and begin burning precious family heirlooms," Pietro teased from the couch. In reality, the line of DVD cases on the coffee table and the set of board games beside it told a different story.

"Uh-huh, sure," Clint said. He wasn't going to rise to the bait. Instead, he simply raised an eyebrow at Pietro and got a cheeky smirk in return. Okay, so, really they were leaving the kids with Wanda. He nodded to Wanda. "You're in charge."

Pietro protested as Clint and Laura left, leaving the twins, Cooper, and Lila behind to hopefully not destroy the house in their absence.

"Sooo, can we go now?' Cooper asked, jumping up onto the other end of the couch and looking expectantly at Pietro.

"You have to wait until they've made it to the end of the driveway," Pietro replied, "Precautionary measures and everything."

"Once again, I'm voicing my opinion that your idea is horrible," Wanda said.

Lila nodded. "Mom and Dad would be mad."

"Exactly, which is why we're not going to tell them, right?" Pietro said, reaching out and poking Lila in the middle of her forehead.

"I'm not a snitch," she replied defensively, turning her attention back to the nail polishes.

"Lila, you can't say anything," Cooper said, "You neither, Wanda."

Both of the girls looked at Cooper and Pietro with withering expressions. As if they would tell Clint and Laura, especially when they would possibly get in trouble for not trying harder to stop them. If the boys decided to race around the countryside while their parents were gone, that was their choice.

Cooper walked over to the window and stared out the curtains. "I can't see them anymore. They're out of the driveway."

"Give it a couple more minutes, they might've forgotten something." Pietro was lacing his sneakers, the ones that Tony Stark had sent over a week ago. Apparently they would hold up better to the strain of constant high speeds, so Pietro wouldn't come home in tattered shoes again. The idea was that if somehow Clint and Laura found out about the excursion, whether the girls snitched or they were picked up on an Avengers satellite, they could say they were testing out the prototype sneakers.

"What are you going to do if the Captain or Natasha find out?" Wanda asked her brother, raising an eyebrow at him, "How are you going to talk your way out of that?"

"There's no reason I can't go for a run with Cooper," Pietro said. He rolled his eyes and headed over to where Cooper was still perched at the window. He ruffled the kid's hair and grinned. "Ready?"

"Heck yeah!" Cooper shouted and rushed off for the front door. He opened it just in time to see something crash into the front yard, sending a wave of dust into the air.

The thud caught Wanda and Pietro's attentions. The twins shared a look before getting up and hurrying to the door, Lila following after them. She squeezed in between them and stood beside her brother as the cause of all the noise stood up and brushed himself off.

"Mr. Thor!" Cooper said, his eyes wide, "What're you doing here?"

Wanda stepped up behind Cooper, watching the destructive Asgardian carefully. She liked Thor well enough, but things happened to get crushed or ruined when he was around and forgot exactly how strong he was.

"Hello, small Hawkeyes and you other two," Thor said, straightening up and grinning. He was wearing jeans and a black t-shirt, and his long blond hair was tied back in a ponytail. "I came to see if Clint and Laura were home. I have much to discuss with them about, er, important topics."

"He's out with Mom," Cooper said. He jumped off the porch and headed over toward Thor. Walking in a circle around the Asgardian, he gave Mjolnir a quick poke. "He's getting retired anyways, so he can't help much."

"It's not about heroism, young hawk," Thor said, looking bemused, "Unfortunately."

"Now I'm curious," Pietro said. He dashed down the stairs and stood in front of Thor, crossing his arms over his chest. "If it's not work-related, then what're you here for?"

"It's not important," Thor said.

"Oh," Wanda said, getting a glimpse at the foremost thoughts in Thor's blond head. She didn't use mind control or telekinesis in the house, but this was technically outside of the house. Plus, Thor wasn't a part of the family. Wanda smirked. "Troubles with Ms. Foster?"

Thor gave Wanda a frown and then clapped his hands together. "Well, since Clint isn't here, I'll go then…"

"Wait, wait," Cooper said, grabbing Thor's shirt and pulling back, "Hold on. You can't just leave! You didn't stay long the last time you were here, either."

"Yeah," Lila piped up. She stood beside Wanda, her hands on her hips. "And you broke my house."

"I apologize for that," Thor said, shaking his head and remembering the destroyed building block creation.

"You know, I think if Thor was a true gentleman, he'd help you create a new house," Wanda said, her smirk growing into a mischievous smile, "It's only the honorable thing to do."

Thor looked at the kids, who were both giving him hopeful looks, and sighed.

And that's how when Clint and Laura got home they found an Asgardian-shaped cityscape of Legos in their living room and Thor, Lila, and Cooper napping on the living room rug while Wanda and Pietro watched reruns of old 80s shows.
