Author's Note: This idea just popped into my head and I couldn't resist writing it out. It's so self-indulgent and mushy, but I don't care. Forgive me for anything too far fetched, but it's a show about the supernatural.

Scott sank down into the couch in his living room, relishing in the comfort of being home again. It was early summer and everyone had come back to Beacon Hills between semesters. Scott had settled in nicely on his path to becoming a veterinarian and everyone else was happy with what they'd chosen as well. After taking care of the threat from Tamora and her army, there hadn't been much drama, not that Scott was complaining. Not being in constant danger was pretty nice. Everyone coming home was just the icing on the cake in his opinion.

A few hours later and the "party" was in full swing. And what he meant was everyone was kind of milling around the McCall house, moving between the kitchen and living room. Scott and Malia were squeezed on the couch with Stiles and Lydia, while Corey, Mason, and Liam were trading war stories about the finals they'd just finished in the corner.

His mom, Sheriff Stilinski, and Derek were in the kitchen, chatting about how nice it was to have the kids home over glasses of wine. Derek had taken to hanging out with the parents recently, somehow turning into a mellow old man after everything. Mr. Argent was on his way, but running a bit behind. He'd had to fly back to France for something, but promised to bring back something nice for his mom to make it up to her. Scott could admit that their relationship had been a little weird for him to get used to in the beginning, but his thoughts didn't matter when he saw how happy his mom was. She deserved whatever made her smile.

A knock on the door pulled Scott from his thoughts and he moved Malia's legs off his lap so he could stand up and answer it. Most people just walked in these days, so he was intrigued about who it could possibly be. He pulled open the door to find Mr. Argent on the other side.

"Hey, since when do you knock?" Scott asked, staring at the man in confusion. He was about to ask him if everything was okay when his breath caught in his throat. Chris hadn't come alone. Five years ago, after the worst night of Scott's life, Chris and Isaac had taken off to France before they even had a funeral for Allison. Scott assumed they were taking her body back to be buried along with the other Argents, but he'd never had the courage to ask. He was just now realizing how wrong he'd been. Allison was alive.

"Hi Scott," Allison said softly as she stepped along the walkway to the house. Scott had to grip the door, feeling lightheaded all of a sudden.

"How?" Scott gasped, lacking the ability to form more words.

"We'll explain everything," Isaac said, coming up to stand behind Allison.

"Isaac?" Scott choked out, finally realizing his old friend was there too. He looked the same, except for the addition of the two children who were currently attached to him.

"Scott, I need you to breathe," Chris directed, putting his hand on his chest to help ground him. Scott was so overwhelmed right now that he put all of his focus into following the instruction, taking a minute to match the older man's breaths. Chris guided him back into the house, making room for Allison and Isaac to enter as well.

"Holy shit," Stiles mumbled in shock, staring wide eyed at the newcomers. The whole party screeched to a halt, even the trio of younger men pausing as they noticed the mood in the room changed.

"Is this real?" Lydia whispered, slowly standing and approaching her previously thought deceased best friend.

"This better not be another wild hunt thing," Stiles growled, looking around the room for clues.

"It's real," Allison confirmed, opening her arms to catch the redhead who threw herself at her body.

"Oh my God!" Lydia cried, holding onto Allison for dear life.

"And what are those?" Stiles asked, pointing at the children Isaac was holding.

"They're my kids, so watch what you say," Isaac warned. The little girl who was riding on Isaac's back lifted her head from where it had been tucked against his neck and let out a little hiss in Stiles' direction before ducking back down again. The baby strapped to Isaac's chest let out a pleased gurgle.

"Okay, I'm gonna need like all the details," Stiles said, backing up with his hands raised.

"We should probably sit down for this, since it's kind of a long story," Chris said, grabbing onto Scott's mom's hand from where she'd been standing back in shock. Soon enough everyone was settled around the room with Chris, Allison, and Isaac in the middle of it all on the couch. The little girl was still perched on Isaac's shoulders while he was cradling the baby as he fussed a little.

"Start from the beginning, please," Lydia requested. "This is making me question everything I felt that day. I was so sure you were gone."

"I was, sort of. Or at least for a while. It's pretty complicated," Allison said, turning to her dad to explain further.

"I really did think Allison had died that night. I took her body-" Chris cut himself off to clear his throat, obviously still affected by the events of that day. "I took her body back home after all the lies. I couldn't bear the thought of subjecting her to an autopsy or embalming."

"Chris gave me a moment alone to say goodbye and, um…" Isaac trailed off. Allison grabbed his hand and gave it a kiss, urging him to go on. "I could've sworn I heard the tiniest little thump. I was sure it was just a trick, but I called Chris in and he calmed me down so I could listen more closely. And there it was. There she was."

"You were still alive, after all that time?" Scott gasped, feeling breathtakingly guilty. Knowing he could've done more made him sick. "I could've sworn I felt you slip away."

"It wasn't my heartbeat Isaac heard, Scott," Allison said, running her hand through the little girl's hair. "It was Celine's."

"I never thought my daughter having unprotected sex with a werewolf would save her life, but here we are," Chris mumbled.

"Dad!" Allison yelled, shaking her head in frustration. Isaac was blushing harder than anyone Scott had seen in his life.

"What's sex?" the little girl, Celine, asked curiously.

"Thank you Chris," Isaac sighed, turning his attention back to his daughter. "Don't worry about that right now, sweetheart. Mommy will explain later."

"Why me? You know you're her favorite," Allison scoffed, bumping Isaac with her elbow.

"It was your dad who opened up that particular can of worms, years early might I add. You clean up the mess," Isaac shot back.

"Wow, you guys sound like an old married couple," Stiles snorted, shaking his head in amusement.

"Well…" Allison started, before Lydia grabbed her left hand in shock.

"You got married!" Lydia exclaimed, inspecting the simple silver band on Allison's finger. "Um, it's nice."

"Isaac made it himself, with help from my dad," Allison gushed, smiling at the memory.

"That's so sweet!" Lydia cooed, grabbing Isaac's hand so she could see his matching ring.

"I've gotta say, I never really pictured Allison Argent becoming Allison Lahey," Stiles commented, earning a slap on the leg from Lydia. "No offense!"

"She's not a Lahey. I'm an Argent," Isaac shrugged.

"That's so like, progressive," Mason said.

"Allison's family lineage means more to her than mine ever did, so it was the natural choice," Isaac brushed off, eyeing the trio a little.

"Oh, I'm-"

"Can we hold off on the introductions for now?" Stiles interrupted, waving his hands in a "hurry up" motion. "I'd really like to hear the rest of the explanation of how Allison came back to life."

"Well, we took her to a powerful shaman I'd met previously. Someone who was well versed in all sorts of lore," Chris explained, looking over at his granddaughter. "There was only one chance and it was risky, but doing nothing would've meant the end for both of them. Luckily, little Celine was special."

"She had the spark," Derek said knowingly.

"The what?" Malia asked.

"The Alpha spark. I used mine to save Cora from the mistletoe poisoning," Derek explained.

"I'm not sure what the shaman did, but it worked. Allison was healed and woke up like nothing happened," Chris said, beaming with pride at his little family.

"Wait, how far along were you? Why didn't you tell me you were pregnant?" Lydia asked.

"I didn't know. It was kind of impossible to know, actually," Allison replied.

"Evidently werewolf pregnancies progress a lot faster than normal ones, so prepare yourselves for that one," Isaac said with a wince.

"This is so hard to wrap my head around," Lydia sighed, staring up at Allison. "Why did you leave? Why didn't you tell us you were okay?"

"Everything that happened was just so overwhelming. And with dad coming back here to help with different issues, it just felt safer to stay in France. I needed to protect my family," Allison said, running the back of her finger along the baby's cheek.

"I don't blame you," Lydia breathed out, staring dreamily at the little children. "They are so beautiful."

"It's a bit unfair how much they resemble Isaac. Dad's features are pretty similar though, so I guess I never really stood a chance," Allison murmured. She was accurate on that front. The kids were all Isaac, with their light brown curls and big blue eyes.

"But they got your spunk," Isaac commented, easing his head away from where his daughter was still resting. "Celine, will you please stop chewing on daddy's ear? Go to Pop Pop, okay?"

"Pop Pop!" Stiles whisper-yelled, tipping back in delight.

"Hey Alli, I think Julian's hungry," Isaac said, handing over the baby.

"That's my cue to go!" Stiles yelped, scampering into the kitchen as soon as Allison started unbuttoning her blouse. The rest of the men followed suit, with Isaac giving Allison a peck on the lips as he went. Celine trailed after him, clutching at his pant leg as he walked. They settled around the dining room table, with Isaac bouncing his daughter on his knee. It was a very strange thing to witness.

Scott could never imagine Isaac with kids. None of them really, but it wasn't really a thing a teenage boy thought about much. Seeing him now though, Scott could never remember seeing Isaac more content.

"Hey baby, why don't you go sit with mommy for a bit? Maybe share your snack with her?" Isaac suggested, pulling a bag of crackers out of one of his pockets. The little girl squealed in delight, grabbing her treat and scampering back into the living room to sit with the women.

"This is bizarre," Stiles mumbled, staring at Isaac like he was an alien.

"You look happy," Scott said fondly, patting Isaac on the shoulder.

"I am. I'm the happiest I've ever been," Isaac admitted, smiling gently.

"I'm so happy to hear that. We've really missed you," Scott said, squeezing Isaac's shoulder once before letting go. "Tell us what you've been up to, besides the obvious."

"Yeah, two kids? I can't even keep a plant alive," Stiles snorted.

"It's true. Somehow he even wilted a plastic plant," Sheriff Stilinski said.

"I was terrified when I first found out Alli was pregnant. Added in with everything else that happened, I was pretty overwhelmed," Isaac confessed, rubbing the back of his neck. "But when I saw that little face for the first time, all that doubt went away. I knew I'd do anything for that little girl."

"How did you deal with it all? Becoming a parent at 17 had to be hard," Scott wondered.

"Well, luckily Chris was able to set us up with some private tutoring to finish up school. After that, Allison started training the younger generation of Argents and dipping her toe in the arms dealing business," Isaac explained.

"And what have you been doing?" Stiles asked.

"I've kind of been doing the stay at home dad thing," Isaac admitted, rolling his eyes at Stiles' cackle. "I guess you could say I'm a bit overprotective."

"I hired them a nanny and she lasted six minutes. Or rather Isaac lasted six minutes," Chris snorted.

"She didn't smell right," Isaac said defensively.

"It took two years before Allison could convince Isaac to leave Celine with me so they could go out to dinner."

"But I did, didn't I?"

"It was a picnic and you never left the property!"

"It's a wolf thing," Derek chuckled, sending Isaac a knowing look. "I swear, my mom hated letting us out of her sight until we were like eight years old."

"So, you've only got about seven years to go before you're normal again?" Stiles scoffed.

"Well…"

"Isaac, you better not have gotten my daughter pregnant again!" Chris hissed.

"Of course not," Isaac muttered, rolling his eyes. "Alli said she only wants to nurse one baby at a time."

"I guess that buys a little time."

"Although Allison is planning on weaning Julian pretty soon."

"Oh my God."

"Don't act like you didn't bawl the first time Celine called you Pop Pop. You love those kids and you'll love all the others we have too."

"Others? How many are we talking here?" Chris asked.

"I mean, the number isn't set in stone or anything, but we were thinking at least five," Isaac responded.

"Five!"

"Nah man, you gotta make it an even number. Go for six," Stiles suggested.

"That's what I said," Isaac nodded in agreement. "Alli said we'd talk after five, but six just makes a lot more sense."

"Don't ask me to babysit," Stiles laughed.

"Stiles, I wouldn't trust you to watch my jacket, let alone my kids," Isaac snorted.

"Justified, but still hurtful," Stiles grumbled.

"Can I try?" Malia's voice asked from the other room. Isaac's ears immediately perked up and he pushed back from his seat, walking quickly to the living room. Scott followed, worried about Isaac's sudden reaction and wanting to make sure everything was okay. Malia was standing in the middle of the room holding the baby out in front of her like she was trying to figure out what it was.

"Alli?" Isaac grumbled.

"It's okay, Isaac. Malia just wanted to try burping Julian," Allison explained. That didn't seem to calm Isaac any, because he kept hovering around Malia, looking ready to pounce.

"I don't know about this," Malia said, scrunching her nose up at the baby. All of a sudden she yelped and wavered and Isaac swooped in and grabbed the baby, pulling him protectively to his chest with a smirk. Scott looked down and noticed the little girl scooting away on the floor and Malia rubbing at her ankle.

"Be nice to my brother!" Celine growled, climbing Isaac like a tree and latching herself to his back.

"She's a biter," Isaac shrugged, kissing his daughter on the temple.

"I can see that," Malia muttered, looking over at her. "My kind of girl."

"How did he eat?" Isaac asked, sitting back down next to Allison and positioning the baby over his shoulder with a towel.

"Like a champ, as usual. I don't think the flight affected him like you were worried it would," Allison replied.

"That's good," Isaac murmured, patting the baby on the back.

"I can't believe you were able to keep something like this from me for so long," Scott's mom said, slapping Chris lightly on the chest.

"Well, I-"

"Please don't be mad at him," Isaac interrupted, shooting her his puppy dog eyes. Good to see those hadn't changed. "He was just respecting our wishes."

"Of course I'm not mad," she assured them both, walking over to pat Isaac on the cheek. "I can respect a man who knows how to keep his mouth shut. But I hope you realize I'm going to spoil these kids like they're my own grandchildren."

"I remember how good of a mom you are. They'll be lucky to have you in their lives," Isaac said with a smile.

"We'll be lucky to have all of you. We really missed you," Allison agreed, looking around the room.

"Does that mean you're staying for good?" Lydia asked hopefully.

"That's the plan," Allison confirmed. Lydia squealed and wrapped her arms around Allison.

"Do you have any idea what's going on?" Mason whispered to Liam.

"Not at all," Liam mumbled.

"I think it's sweet," Corey sniffled, wiping at his eyes. "Don't look at me."

"Did one of those guys just disappear?" Isaac asked, staring at the spot Corey had just been standing.

"Don't worry about it, that's just something he can do," Scott brushed off.

"We really have missed a lot, haven't we?" Isaac said wistfully, rubbing his cheek along his son's back.

"Maybe, but that doesn't matter anymore. Now you're home."

Author's Note: This might turn into a series, because I love the idea of over protective dad Isaac, but I'm not sure yet.
