He picked up the phone and heard the familiar voice of his secretary on the line. Putting his fingertips to the bridge of his nose he answered. "Get me Detective Mac Taylor."

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Chief of Detectives Michael Sullivan waited patiently to take the elevator up to the 35th floor of the NYPD Crime Lab, doing his best to avoid the ass-kissing detectives that usually crowded him. He'd hung up the phone when he'd gotten Mac's voicemail and decided go there in person, bringing Sam's personnel file.

He'd always been a patient man in delicate situations like this and since his daughter was involved he wasn't about to change the way he presented himself. He knew that if he went off on Mac half cocked he'd not only be embarrassing himself but jeopardizing his relationship with his daughter. His daughter. Questions needed answers and he was going to do anything for her to get them without her getting hurt.

Sullivan noticed a familiar face walking towards him while engrossed in a conversation with another detective. His black well-fitted suit fit him well as his blue shirt accentuated his amazingly blue eyes. The one detective parted ways as Detective Donald Flack, Jr. headed towards the elevator and noticed Sullivan's presence.

"Chief Sullivan," he said surprised, firmly shaking the man's hand. Flack had been one of the few detectives that Sullivan truly like to be around and didn't hold his father's career over his head, something that Flack had graciously liked about him. Michael allowed Flack to be himself and Flack knew that unlike most cops didn't hold expectations on him purely because of who his father was. "You're your own person". He'd said to Don during a previous conversation. He liked Flack because he wasn't trying to impress him like most detectives were and because he'd shown him nothing but respect. Flack admired Sullivan for his direction and his 'down-to-earth' approach to his work as well as his way of handling politics without being succumbed to the bureaucracy of things. Both men found a strong trust between each other.

"Detective Flack," Sullivan grinned and returned his shake. With a ding, they entered the elevator once it cleared out. Halfway up to the 35th Sullivan spoke. "Collins told me about that jewel theft case you and him worked on last week. $950,000 worth of lost valuables…" Flack nodded reminiscently. He was still pissed since Collins had taken complete credit for the bust and recovery. Sullivan looked straight ahead. "Good Job…" he said smiling, showing Flack that he knew what Collins had done. With a ding of the elevator, Sullivan stepped off onto the 35th floor with Flack following suit.

"Thank you, sir." Don said trying to hide the smile, parting ways with the Chief.

Sullivan saw Mac Taylor through the glass walls, working at this desk, engrossed in a file. He knocked before entering as a surprised Mac shifted his attention away from the file. He stood up and reached out and shook Sullivan's hand.

"Chief, this is a surprise. What can the crime lab help you with today?" Mac said curiously. Sullivan motioned for him to sit before he continued. Sullivan took out a copy of the adoption letter from her file and set it on Mac's desk.

"I'm not here for the crime lab, Mac. I'm here for my daughter." he said reluctantly. Mac looked at him inquisitively as he took the letter. Sullivan sat in one of the vacant chairs across from Mac and leaned forward, resting his forearms on his legs and pinching the bridge of his nose as Mac studied the letter.

Noting the adoptee as Samantha MacAiden Sullivan, he continued. He knew that the chief had a daughter and he'd seen her from a distance, but was never introduced. He never suspected adoption as her deep brown hair and facial features similarly matched her fathers. The only difference was her mysterious brown eyes since he had blue and his wife had green. He read over the Biological Parent Information and a feeling of astonishment and shock erupted in his body. He'd read it twice, then three times before setting it down. Biological Mother: Aiden Katherine Thomas. Biological Father: Mac Taylor. Memories from his past came flooding back before Mac took in a deep breath.

Sullivan noticed the immediate change in Mac's demeanor. Mac stood up from his chair and walked to the window, trying to take in the information.

"I'm not here to interrogate you, Mac. I'm just looking for answers, just as my daughter will be if she decides to follow through with coming here. I need to know if there's even the slightest possibility that this is record is true." He nodded and turned back to Sullivan and sat back into his chair.

"I was about twenty when I met Aiden…"he started hesitantly. "We had just gotten back from fighting in the Middle East and were going to be sent back over the following week. I was on leave for the four days and my best friend and I decided to take short trip to New York before leaving the states." Mac rubbed his eyes. "We were walking in Times Square," he smiled," when this fiery, brunette Navy nurse grabbed the front of my uniform and said, "Who needs a sailor, when you got a marine." He smiled at the memory as Sullivan looked at him waiting for him to continue. "It was the best time I'd ever had in my life. 'That crazy kind of love' she called it…We saw her off, before she left. Promising each other we'd keep in touch, but I never saw her after that. We sent letters back and forth before I got one letter telling me that when I got back to the states, she needed to see me…I never suspected this." he said motioning to the letter.

Sullivan nodded before pulling a small child's hairbrush in a plastic bag from his pocket, running his hands over its features. "Mac…, I need to be sure. She's been through more hell than you can possibly imagine and I don't want her coming in here...with false hope." he said looking Mac in the eyes. Mac nodded. He knew that Sullivan was right in every aspect. "Okay," Mac said.

They were in the DNA lab, noticeably to everyone that curiously walked by, when they confirmed the results with Mac and Samantha, an awkward silence following. Sullivan drew out a long sigh as he set the results on the table.

"Where do we go from here?" Mac asked quietly, still shocked at the results.

"Wherever you want…" Sullivan said hopefully. Mac slipped off the gloves, throwing them in the garbage and both stopped outside of his office.

"I uh…think you might wanna read this." he said hesitantly handing Sam's file to Mac. "I didn't think I was gonna bring myself to say this, but I'm warning you, Mac…"he started as Mac put up a hand in understanding.

"I have no intention of hurting either her or your family…I just wanna make up for lost time. Make things right." he said understanding where Sullivan's emotions were coming from. Sullivan nodded and shook Mac's hand. He turned and made his way to the elevator as Stella walked towards Mac acknowledging the Chief's presence. She looked at Mac curiously as they watched Sullivan get on the elevator.

"Everything okay, Mac?" she said concerned, as she noticed Mac tighten his grip on the file. He smiled.

"Yeah…you got a minute?" he said as he headed into his office with her following.
