I do not own Hawaii Five-0 or any characters. No copyright infringement intended. The same goes for the fantastic show and wonderful characters portrayed in Flashpoint.

Notes: the following is strongly based on an Episode of Flashpoint. One of my total favorites. Season 2; episode 16 "You Think You Know Someone", written by Adam Barken and directed by David Frazee. Special thanks always and forever to CinderH and JazzieG (best, most talented Beta's EVER)!

Chapter One

It started with a simple text message.

Help.

Bar on Keeaumoku Street.

Ana.

Danny didn't hesitate in changing direction on the freeway. He had known Ana for a very long time. For more years than he could now count .. from a time back in New Jersey when she was only 8 years old and he had just been promoted to detective. Now nearing her twentieth birthday, she had moved to Hawaii to start a new chapter in her life. She had unexpectedly knocked on his door one late evening after work to surprise him. And after only sharing emails and letters for three years, he had been rendered utterly speechless by the sight of the pretty young woman standing before him.

He had stood there barefoot, Longboard in hand and in total shock. He had barely managed to blurt her name out before she was in his arms. "Ana?"

"How did I know he asks?" She mocked him kiddingly as he pulled her into a Danno-sized hug that maybe had only ever been reserved for Grace.

"I was practically raised by a cop, Uncle Danny. Really? It wasn't exactly difficult to find you." That had been six months ago and Ana was now working for a large hotel chain as a public relations assistant.

They met for the occasional lunch or walk on the beach. Nothing too over the top because Ana was settling in and meeting appropriate people in her age group. She was maturing and he gave her both the space to find herself or the time she sometimes needed to share the fun and mundane moments of her first real job. He understood that on some level Ana still sought his approval, but was she was also happy and content for the first time in a long time. She loved her job and Danny loved seeing her success.

It was Monday morning and he was on his way into the office after having dropped Grace personally off at school. They had an exceptional weekend and Danny was in high spirits. He was already running late, but the priority box of mixed malasadas sat where Grace had been on the passenger seat of the car. However, with the vague text from Ana, he felt an old, familiar tight knot in his stomach.

Help.

Bar on Keeaumoku Street.

Ana.

He sighed worriedly as he hit speed dial to call Steve. His call was answered almost immediately and based on the early morning background laughter, he wasn't surprised that everyone was already in the office.

"Hey Steve."

He rolled his eyes to the roof of his Camaro at Steve's first words. "You're late, pal. We have a meeting in 10."

"Yeah, about that. Something personal's come up and I'm going to be a little later than planned."

He could hear movement on the other side and guessed correctly that Steve had gone to his office so he could close the door. "Is everything alright? It's not Gracie is it?"

"No, no, no. Calm down Uncle Stevie .. Grace is fine." Danny couldn't help grinning as he took the u-turn on the freeway that would loop him back downtown.

"It's all fine. I just have a small errand to take care of and then I'll be in."

"You sure?" Leave it to Steve to push, and the nudge became a shove in less time than it took for Danny to merge into traffic.

The grin grew across Danny's face as he wove in and out of cars and trucks towards his destination. Steve was pleading for more information, but this was truly personal and Danny wasn't willing to discuss this one particular thing. It pre-dated their friendship and hell, it even pre-dated him and Rachel. But just barely at that; and even with the ongoing calls, visits, emails and text messages that followed into their marriage, not even Rachel was aware of this one, very special relationship.

"Because .. I can help." He had zoned out and the back again as Steve's voice took on a plaintive tone.

"Danny? Are you there? Is everything alright.. do you need any help?"

His sigh was audible and for that, he silently apologized because his partner would pick up on that as a subtle clue. So blaming it on the heavy, rush-hour traffic, he hung up quickly. "No, I'm good. I'll see you within the hour."

After that, Danny drove just a bit faster to reach Ana. Even in that short text message, he thought he could feel her fear.

But he had left Steve staring a bit bewildered at his phone. Completely still in his office, he only looked up when Kono entered with a questioning look on her face.

"What's up?"

"Nothing." Steve frowned and then shook it off. "Danny's running a bit late ... we can begin without him."
