Derek looked at the two teenagers in front of him, very reluctant to entrust them with his car. He shifted his gaze between the two of them, trying to decide which one was more responsible but it was a tough call. Finally he decided that though Stiles would probably try to incite a car chase, he was a marginally better option than Scott, who would no doubt be texting Allison non-stop.

Derek dropped his keys and Stiles' hand and the teenager started to celebrate. Derek grabbed the collar of his shirt. "If I find one scratch…" He left the threat open ended and shoved Stiles away as Darcy entered the room.

She laughed and went to take a pie out of the oven. "Be nice to my cousin, Derek."

"As long as he's nice to my car…"

Darcy smiled and set the apple pie to cool, inspecting the crust and declaring it passable. Stiles' face appeared by her shoulder. "You gonna share that?" he asked.

"It's probably really hot right now, but you can have some," she said. "Of course wouldn't you rather play with Derek's car?"

Stiles nodded and grabbed Scott on his way out the door. Scott trailed behind, finding it difficult to text and be drug along by his hyperactive best friend.

Derek wrapped his arms around Darcy from behind and rested his chin on her shoulder, his stubble tickling at her ear. She felt the twins start to move and took Derek's hands, placing them over the place she'd felt the movement. The twins were still for a moment and then started to move again.

"Can you feel them?" Darcy asked.

"I think so," Derek said softly. "It stopped, but it felt like a little bump."

"You'll definitely be able to feel it later on."

"I look forward to it." Derek kissed her cheek.

Stiles sped down the street and passed the Argent family home in a black blur. Scott was in the passenger seat, clinging to the door.

"Is that really necessary?" Scott asked.

"No," Stiles said with a laugh. "Hey, did you see anyone there?"

Scott hesitantly replied. "No…they all went to some event for Allison's mom's job."

"So, their fortress of crazy is abandoned?"

Scott took on his most serious tone. "No, Stiles. Absolutely not."

"Come on! It could be useful. We could find out what kind of weapons they're packing so they lose the element of surprise."

"It's their house though…I mean…isn't that wrong?"

Stiles found a secluded place to park Derek's car. "Wrong is all a matter of perspective. I say it's wrong of them to try to kill my best friend."

Scott shrugged. Stiles did have a point, but the young werewolf was still a little uneasy about the idea.

"Come on, Scott. I'll do all the dirty work. You can just sniff Allison's pillow or something."

"This is a bad idea…"

Stiles just laughed at his best friend's squeamishness as he walked around the perimeter of the house, trying to find an entrance.

"Everything looks great," the ultrasound technician said. "Good heart rates, perfect size for their development."

"That's great," Darcy said.

"Let's take another look at the gender, just to make sure," the ultrasound tech said, moving the wand a bit. She squinted at the screen. "Yeah, definitely a boy and a girl! Have you picked names?"

Darcy grinned and took Derek by the hand. "Laura and Ayden," she said.

"Cute, cute…" the tech muttered as she made a few notes. She looked up and smiled at the young couple. "Is this the father?" she asked.

"Yes," Derek said, before Darcy could say anything.

The technician stood and started to pack up the machinery. "Those are gonna be some beautiful babies," she commented with a wide smile. "The doctor is on her way to discuss your blood work."

Darcy nodded as she wiped the ultrasound goo off her stomach with a tissue, thanking the tech as the door closed. She looked at Derek, unable to speak because of a lump in her throat.

"What?" he said.

Darcy sniffled. "You said you were the father." Her eyes filled up with tears and she mentally cursed the crazy hormones.

Derek nodded. "Of course I did."

"Why?"

"Because I love you."

Stiles opened a cabinet of guns and reached out to touch the most dangerous looking one.

"Don't touch that!" Scott said, shifting uncomfortably. "This was a bad idea…"

"I'm just looking," Stiles hissed. "Come on, all that's here is guns." Stiles gasped. "We should go into her dad's room!"

"No! I don't know how, but he'll know if we do that, Stiles."

"You said you couldn't see any sign of a security system. We'll be fine. We'll just put everything back the way we found it." Stiles said, waving off Scott's concerns as he checked the door that led to the kitchen.

"We should just get out of here, Stiles. Seriously, I have a bad feeling."

"You can look in Allison's underwear drawer…" Stiles taunted as he swung the door open.

Scott closed his eyes and checked for the thousandth time to be sure that his and Stiles' were the only hearts beating in the house. "We're gonna get caught…" Scott said as he followed after Stiles.

"Just think of the lacy thongs, my friend."

Darcy slid up close to Derek as he closed the door to Stiles' Jeep and kissed him. He seemed surprised and delighted by her aggressiveness. She slid her hand over his abs as he kissed her neck and collarbone.

A shrill chirping interrupted them. They were both startled. Darcy groaned and reached into her purse, fishing around for the plastic brick that was her temporary cell phone.

"It's Stiles," she muttered. She opened the message and read it to herself. "I'm gonna kill him," she said, showing the phone to Derek.

Me & S stuck in Argents house, come rescue -Stiles

Derek pinched the bridge of his nose and started the Jeep, cursing under his breath.
