A/N: Yeah, I shouldn't be starting another story, but I am. This is sort of a Kono/OC story but it'll eventually be D/K because I'm me and I like Danny and Kono, and there will also be a crime element as well. This is actually the first story I've ever written with a major original MALE character, so I based it on someone. If you can guess who I am envisioning as Jack, I'll give you a shilling (well, a virtual shilling). Enjoy!

Kono knew she was being paranoid. Not only was she technically on vacation, she was at the beach and her shoes were half a mile away in her car. Despite those conditions, however, her kal-tech from McGarrett was securely tucked into the back of her shorts and her badge was clipped to her waistband. Her loose t-shirt concealed both, but she certainly recognized the underlying insanity. She even had a couple sets of zip-cuffs in her back pocket. She honestly had no idea how she was going to deal with trouble in her bare feet, but she would certainly try.

An unusual voice caught her attention. It's masculinity was not unusual, but the distinctly English accent was certainly attention-getting. The owner of the voice was wearing the bottom half of a gray suit and white shirt and was playing an impromptu game of soccer with some local kids. His laugh was loud and genuine as he combed his thick, brown hair out of his eyes with his right hand. He was distinctly European-looking with a high forehead, long, straight nose, and hooded eyes. Kono would not have naturally thought he was good looking, but she couldn't say he was bad looking.

She moved closer to the game and paused by a duffel and a messenger bag covered by a gray suit jacket. She surmised the stuff belonged to the English guy as the jacket matched his pants. She hazarded a closer look and her body instantly tensed. Under the jacket was a nice, shiny handgun.

The Englishman noticed her and stepped out of the game, followed by the protestations of many of the children. Kono noticed that he too was in his bare feet. At least she had that going for her.

"Hello," he said, slightly out of breath as he brushed his hair from his forehead. "Is something wrong?"

She eyed him suspiciously and said, "Why would something be wrong?"

"You seem…tense," he replied, slowly moving toward the pile of bags and consequently the gun. "I asked to join the game. I didn't bully my way in if that's what you're concerned about."

"Oh, I wasn't concerned about that," she replied flatly.

"So…is there some reason you're staring at me in such an odd fashion?" he asked as he reached down into the pile.

At the same instant, he drew his gun and she drew hers. The children in the area immediately scattered.

"Drop it," she ordered.

"Not likely," he replied.

"What are you doing with that weapon?"

"What are you doing with that weapon?"

Kono lifted her shirt enough to reveal her badge and said, "Kalakaua. Five-0. Drop the gun."

"Oh. You're Five-0. Sorry," he said, taking the barrel of the gun in his left hand before passing it to her.

Kono couldn't help but raise an eyebrow as she took the gun and noted it was a Walther. She tucked it into the back of her shorts and kept her own gun pointed at him. "Put your hands on your head and turn around."

"Is that really necessary? I—"

"Put your hands on your head!" Kono replied more forcefully.

"Okay, fine," he said quickly, turning around with his hands on the back of his head.

Kono put her gun in her pocket and withdrew a set of zip-cuffs from another. She bound his hands together and turned him around, taking her gun back out. Before she could order him to the ground, he said, "There's really a perfectly logical explanation for all of this. Call Danny. He'll vouch for me."

"Danny?"

"Yes, your partner, Detective Danny Williams. Call him."

"Why would I do that?"

"Because it will save you an awful lot of embarrassment and paperwork."

"And what should I tell him?"

"Tell him he needs to help Jack Harper out of a jam."

Danny wished he had more friends on Oahu. Steve and Chin had gone spear fishing. They invited Danny even though they knew he'd say no. Kono decided to take a walk on the beach, something Danny never did unless his daughter was begging. Consequently, he was driving around Honolulu by himself in the middle of the week. He was frankly a little annoyed the governor had given them the week off.

So he was surprised when his phone started ringing in his pocket. He was further surprised to see Kono's name on the screen. "Heya, what's up?"

"Hey, I'm here at Ala Moana and this guy kind of pulled a gun on me."

"He what?"

"He says you can vouch for him."

"Again, what?"

"He says his name is Jack Harper."

Danny's shoulders immediately relaxed and he smiled though no one could actually see him. "Let me guess: skinny, white, English guy; mid-twenties, shaggy, brown hair?"

"Right on the money," Kono's voice replied in mild shock.

"I'm five minutes away. I'll be right there," he said, flipping the car around and heading for the beach.

He smiled at the image he approached on the beach. The pasty young man was sheepishly sitting in the sand while Kono stood over him with a stern expression and her handgun held out at her side.

"Jonathan Arnold Harper," Danny said loudly as he came into earshot.

"Oh, now that's just unnecessary," the young man complained. "It's Jack. I'm called Jack now."

"Whatever. Why'd you pull your gun on my partner here?"

"I saw she had a concealed weapon. I had no idea she was a cop, much less your partner."

"Wait. You guys actually know each other?"

"Yeah. Why'd you pull on him?" Danny asked, looking back at Kono.

"I spotted the gun in his stuff. He went for his, I went for mine," she explained, handing Danny the Walther from the back of her waistband.

Danny took the gun and looked back at the young man on the ground. "You just left your gun with your stuff? What do they teach you in England?"

"Would you please just let me out of these things? They're quite uncomfortable," Jack complained from the sand.

"Where's your I.D., Jack?" Danny asked, grinning.

"In one of my jacket pockets. Don't really remember which one."

"You are the picture of responsibility," Danny said, handing the gun back to Kono and picking up the jacket. He reached into the inside chest pocket and withdrew a piece of bi-folded leather. He handed it to Kono and said, "There you go. Check it out. You; on your feet."

"That's a bit difficult right now, Daniel," Jack replied irritably as he struggled to stand.

"Do not call me Daniel," Danny replied, pulling him up by the back of his shirt.

"Ow! You called me Arnold. You had it coming," Jack said after nearly losing his balance.

Danny cut the zip cuffs off and Jack rubbed his wrists as Kono said, "You're MI-6?"

"Say it a bit louder, Kono. It's not like he's a spy or anything," Danny teased.

She rolled her eyes at him and passed the badge and gun back over to Jack. Danny took the gun, causing Jack to fumble with the badge.

"What the hell are you doing with a gun, Jack? You don't generally carry a gun in your own country, and I do not see any double-decker buses, so what the hell is this?" Danny asked, holding the gun up by the barrel.

Jack sighed and scratched the back of his head as he said, "Well, you see, I was here, well, the Big Island actually, on sort of…business, if you will, your Justice Department should know about it…by now. Then I came over here on a chartered plane so I didn't have to surrender my weapon and there were some children playing football, so I joined in."

The young man smiled at the end of his speech and Danny looked over at Kono and muttered, "He was playing soccer, wasn't he?"

"Yes," she replied shortly, rolling her eyes.

"You are an idiot," Danny said, pointing at Jack with the handle of the gun.

"I'm sorry. How do you two even know each other?" Kono asked.

"What? You don't think I can know James Bond?" Danny asked, motioning to his chest.

"I am not James Bond," Jack protested, reaching for the gun only to get Danny's hand in his face, pushing him away. He grunted and continued, "Before Rachel's last name was Smith or Williams, it was Harper."

"Jack's my ex-brother-in-law," Danny clarified as Jack reached for the gun again. "You are not getting the gun back."

"Why not?"

"Because you're an idiot."

"You cannot keep that from me."

"You wanna bet?"

Kono covered her mouth to keep from laughing at the growing conflict between the two men. Jack stood a good eight inches taller than Danny, but Danny was wider and far more muscular. Danny was also obviously convinced he could break Jack in half if he needed to. It was hilarious to look at.

"You know what? I'm taking you to your sister's house. I'm sure there's a safe we can put this thing in. Get your stuff together."

"I am not Grace. You cannot order me about."

"Get your stuff together!"

"Fine, fine," Jack muttered, grabbing his jacket and slinging the strap of the messenger bag across his torso. He looked at Kono and said, "I'm sorry we couldn't have met under better circumstances. I didn't get your name. I doubt it's just Kalakaua."

"Kono," she replied, smiling.

"It's nice to meet—"

"Will you come on?" Danny said, grabbing Jack's arm and pulling him away.

"See you again, maybe?" Jack called to Kono.

"Yeah, maybe," she called back, laughing at the sight of her partner dragging his young brother-in-law away.

"What surprise?" Rachel asked dubiously as Danny led Grace to the driveway of her house.

"You can wait and find out too," Danny replied.

"Can I open my eyes now?" Grace asked after her father guided her down the steps.

"Sure."

"It's your car," Grace said uncertainly.

Jack's head popped out of the passenger side door with a giant grin on his face. Grace's demeanor immediately changed from confused to overjoyed as she ran into her uncle's arms. "Uncle Jack!"

"Jack?"

"Lovely to see you too, sister-mine," Jack replied, holding his niece.

"Well, of course, I'm glad to see you, Jack, but you could have called," Rachel admonished, giving her brother a peck on the cheek. "And why is Danny bringing you to my house?"

"Oh, well, I had a bit of a misunderstanding with one of his coworkers, and Danny sort of had to come and rescue me," Jack explained, smiling.

"What sort of misunderstanding?" Rachel asked, looking at Danny.

"Not a big deal," Danny quickly replied. "Hey, Grace, why don't you show Uncle Jack your surfboard. He'll like that."

"You're surfing now, Grace. That's fantastic! Uncle Jack is very proud," the young man exclaimed as his niece hurriedly lead him into the house.

When the two were out of sight, Danny nudged Rachel and said, "I need you to lock this up someplace."

"Daniel, why are you asking me to lock up your gun?"

"It's not mine, it's Jack's. This was the cause of the 'misunderstanding' between him and Kono," Danny explained, holding up the Walther. "I thought Jack was just an analyst. Analysts don't carry guns, Rach, and they certainly don't do it outside of their own jurisdictions."

"Jack's still just an analyst as far as I know, but it's not like he would tell if he's a field agent now," Rachel said, taking the gun and walking into the house while dropping the magazine.

Danny cocked an eyebrow. "You still remember how to do that," he stated.

"Well, I was married to a cop for the better part of a decade," Rachel answered as she opened a cabinet and revealed a steel safe in Stan's office. "Look away, please."

"Oh, yeah, I'm gonna break in to steal all your secrets," Danny muttered, rolling his eyes to the ceiling. "You know, I think Jack is up to something."

Rachel locked the safe and stood up. "Now, you're just being paranoid. Jack is Jack."

"Rachel, can you seriously imagine MI-6 giving your brother a gun? He's an analyst. I mean, I know he's a secret genius and everything, but he would have spent the better part of his childhood in juvie if your family hadn't been so well connected."

"He's twenty-seven now. He's a grown man."

"Yeah, some grown man. He left his gun with a pile of his stuff to play soccer with a bunch of kids on the beach."

"No one is as perfect as you, Daniel," Rachel replied, her voice dripping with sarcasm. "Say goodbye to your daughter before you go."

Danny held in a groan as she stomped out of the room. He made his way upstairs and paused at his daughter's door.

"Sharks are nothing to be afraid of really," Jack's voice said. "The thing you really need to worry about is the ocean itself. It can knock you on your bum quicker than you can say 'hiya'. It's a lot of fun, but you've got to know the water. My mate, Brady, was unconscious for three days for getting in the water when he should have known better."

"Okay, if you were trying to make my daughter learning to surf sound like a good thing; you are failing miserably," Danny said entering the room. "Hey, Monkey, I gotta go."

Grace nodded and gave her father a hug. "Love you, Danno."

"Love you, too. Can I borrow Uncle Jack for a minute?"

"Sure."

Jack followed Danny out of the room and closed the door behind him. "Look, I didn't really thank you properly before, but thanks for not arresting me."

"It's too much paperwork," Danny quickly dismissed. "Jack, you'd-you'd tell me if something was going on, wouldn't you? I mean, I might be able to help."

"Danny, I've told you everything I can. It's fine. Really."

Danny nodded, still not quite believing the younger man. "Okay. I've got Grace this weekend, but if you want to spend some time with her, just let me know."

"I wouldn't want to intrude. You only see her on the weekend."

"Yeah, but you haven't seen her in over a year," Danny replied. "And I'd like to catch up with you too."

"Oh that must have been painful to admit."

"Shut up, kid. See you later."

"Bye, Danny."
