"Don't scare Chris off, daddy," Grace reminded Danny for the umpteenth time since she told him she had a date to prom.

"Chris? That's his name?"

Grace had absolutely refused to give her father her date's name, because she knew he would run background checks and maybe even pay him a visit, and she was right. Danny had used up every single trick in his book, trying to coax a name out of his daughter's mouth, but she had inherited his stubbornness and didn't even budge the slightest bit. Until now.

Grace rolled her eyes. "Yes. Don't intimidate him, and don't pull out the 'I-have-a-gun-so-watch-what-you're-doing' line, okay? I really like him."

Danny ruffled his daughter's hair, and flashed her an award-winning smile that would make the hearts of the sternest ladies melt. "I'll be nice," he answered innocently.

The teen studied his face for a beat longer, as though not completely trusting him, and then turned to go up the stairs, but not before telling him in a matter so like her mother it made him take a step back, "You better be, Danno. I'm going to go get ready."

Watching her leave, Danny fell back onto the sofa with a melancholy sigh. His baby was all grown up now; she was no longer the young girl who curled up at his side every time they watched The Little Mermaid, or the cheeky monkey who would tug on his hair when he settled her on his shoulders. How he wished time would go back to when Grace would insist she was going to marry her daddy when she grew up.

He dreaded this day ever since he and Rachel found out they were having a girl. From that moment, he knew he would love the perfect little bundle with all of his might, and protect her from all of the bad things in the world, hormone-driven teenage boys included. No, wait. Make that the entire male species. They couldn't be trusted; having once been an adolescent himself, Danny was more than familiar with the thoughts that passed through their minds.

If he had it his way, Grace wouldn't have even found out the existence of the other sex until she was at least forty.

The knock on the door broke Danny out of his thoughts, and he frowned. He wasn't expecting anyone, and it was certainly way too early for Chris to arrive. He opened the door to reveal Steve and Kono, the latter almost bouncing on her feet, clearly excited.

"What are you guys doing here?" Danny asked, but still stepped back to let the McGarretts in before heading to the kitchen, letting them shut the door.

"Thought you might need some help scaring the kid later," Steve replied, grinning. There was no way he would let Danny keep the chance of frightening Grace's date to himself. She was his honorary niece after all, and he had to make sure the boy was worthy of taking Grace to prom.

"Where are your pups?" Danny waved a hand in the air, referring to the absence of their kids as he opened the fridge to pull out three bottles of beer.

"At Kono's parents'. They were all too willing to babysit for the night."

Steve accepted his bottle, and went to sit down on the seat Danny occupied not very long ago. Kono shook her head, and said, "I'm going to go see if Grace needs any help," before rushing up the stairs.

"Fine then," Danny walked over to the lounge and settled beside his partner.

"How'd you manage to persuade Rachel to let Grace get ready here?" Steve asked after taking a swig from his beer.

Danny shrugged. "I only asked; Gracie did the rest of the work."

It was true; he only suggested that Grace should stay at his place on the night of prom so he could 'make sure the kid she's going out with won't try anything he isn't supposed to". Rachel wasn't happy at first, but after Grace's infamous puppy dog eyes and the promise to stop by the Edwards' residence, she caved and agreed.

They had a dangerous daughter.

Steve was about to answer when another knock on the door cut him off. He turned, eyebrow raised, to look at Danny, as the other man set his beer on the table and stood.

"You expecting anyone?" The commander questioned.

Danny shook his head, and left to open the door.

The wall blocked Steve's view of the front door, so he didn't know who it was. All he heard was Danny exclaiming, "Really? Not you too. This is turning into a freaking party, isn't it? Did you guys invite anyone else? Should I just leave the door open?"

The chuckle told Steve all he needed to know.

"It's great to see you too, brah," Chin Ho Kelly said dryly as he rounded the corner with his heavily pregnant wife a few steps in front of him.

Like the gentleman he was raised to be, Steve stood and offered his seat to Malia, who sat down with a grateful look on her face.

"Thanks, Steve," she said, rubbing her back. Chin noticed her discomfort and immediately went to her side. "It feels like the baby is having a disco in there."

"Do you want to lie down?" Danny asked, concerned, and when Malia shook her head, he turned around to Chin, pointing a finger at him. "You! Why did you bring your very pregnant wife here when she should be resting?"

Chin held his hand in surrender as Malia laughed. "Relax, Danny, I wanted to tag along. This is Gracie's big day, and I wouldn't miss it for the world. Besides, someone has to watch the testosterone levels in here later."

Feeling the corners of his mouth tug upwards, Danny tried hard to keep his stern face on, but in the end, the smile won and he grinned at her. "Thanks," he said.

He really had the best ohana; he knew he was not the easiest person to work with (especially when his partner was the complete opposite of him), but they still supported him and even adopted his daughter into the Five-0 family. They treated Gracie as if their own, and were present at her (painfully boring) tennis matches, her school plays, and various other things in her life.

For that, Danny would be forever grateful.

"So, what's this kid's name?" Chin asked as he sat down beside Malia.

"Chris."

"Chris…?"

"I don't know," Danny admitted. "She wouldn't tell me."

Steve laughed. "Some detective you are, Danno."

"Not my fault she's as stubborn as her mother," Danny defended himself as he walked into the kitchen to grab drinks for the newcomers.

"I think that's the Williams' genes, actually," commented Malia with a fond smile.

Danny rolled his eyes. "Nah. Definitely Rachel's."

Just as he was sat down on the remaining couch, however, the doorbell rang again. Danny groaned. "Seriously? Who on earth is it this time?"

He reluctantly got up for the twelfth thousandth time that evening, muttering under his breath as he (childishly) stomped out to open the door. His three 'guests' looked at each other in amusement.

"Howzit, my haole friend!" Kamekona's voiced boomed throughout the house.

"What are you doing here? In the civilized world, people don't show up on someone's doorstep unannounced, it's rude! Don't you people have anything better to do than come harass me?" Was Danny's reply.

"Don't flatter yourself, braddah, I came here for the prettier Williams," Kamekona came around the corner, and halted his steps when he saw the room full of people. "What are you doin' here?"

"Same as you, obviously," Steve said.

Kamekona nodded seriously. "Someone's gotta keep an eye on our keiki. Lots of bad men out there."

"You got that right. Hey, that's my seat!" Danny exclaimed at the man who had taken the remaining couch.

"Not anymore. You gotta be quick," he grinned up at the detective. "You see it, you snatch it. Like doin' business."

"This is not business; this is my couch!"

"Just go get another chair, Danny," Chin laughed. "You'll never win."

Throwing an exasperated glare at Kamekona, Danny disappeared into the hallway and came back seconds later with another chair. "This is my house, my couch, and you make me go get another chair?" He grumbled.

"I'm the guest, brah."

"You want a beer, guest?" Steve asked, prepared to get up.

"Nah, I'm good," he replied. "So, you have a plan for later?"

Danny snorted. "A plan? Sure. Open the door, scare the kid. How hard is that?"

"No, no, no," Kamekona shook his head almost sadly. "That's not how you do it, brah. Dat ain't a plan. Hasn't McGarrett taught you anything?"

"Apart from how Neanderthals act when suspects don't cooperate?" Danny tapped his finger against his chin, pretending to think. "Nope. Nothing."

"Hey!"

"You need a plan, haole. Show the kid who's the boss. Luckily for you I know what to do…"
