"I have a what?" Gibbs asked in disbelief as Abby and Tim showed him their findings.

"We don't know for sure if this is her DNA, but the fingerprints are definitely hers, Boss," Tim said.
Gibbs glared at Tim in return. He was obviously still angry about Tim knowing about the DNA. Tim took it as his cue to shut up, and turned to Abby.

"I have the address of her flower shop right here, Gibbs," Abby said, holding up a piece of paper. "I figured you'd want to do this alone."

Gibbs snatched the paper and read the address. He passed that flower shop regularly on his way into work. He'd even bought flowers there a few times.

"McGee, you're with me," Gibbs finally said, heading for the door. Tim scurried after him. Abby shook her head and resumed her work on the rest of the evidence.

Gibbs didn't say a word to Tim until they got in the car.

"Tell me what you know," Gibbs said as he started the sedan.

"I know everything that Abby told you, Boss. Her name is Lena, she's married and has two children. Her file said she owns a Flower Shop."

"Why was she in the system?" Gibbs asked.

"It was a minor misdemeanor back in the late 80s. From what we found, I can't see a woman like this being a murderer."

"We'll just have to see about that," Gibbs said as he drove along, looking for the flower shop. "Prints on a dead body is not a coincidence."

The rest of the ride was awkwardly silent. Gibbs pulled up in front of Sonoma Flowers. It was a beautifully decorated place. There were hanging baskets out front, bursting with petunias and assorted flowers, and potted colorful daisies on either side of the front door. The combination of scents assailed Gibbs as he entered the shop, Tim trailing behind him.

There was a teenage boy sitting behind the counter, engrossed in a magazine. His feet were up on the register, and he was reclined in a chair, with his iPod blasting music loud enough for Gibbs to hear across the room. He was wearing a Metallica t-shirt and baggy jeans, and sported a sideways baseball cap.

Gibbs slapped his hand on the counter, hoping to get the boy's attention. When he didn't flinch, he took it upon himself to walk behind the counter, and hold his badge in front of the kid's face. Upon seeing it, the boy jumped to his feet and tore off his headphones.

"C-can I help you?" he said nervously.

"What's your name?" Gibbs asked.

"Ian."

"We're looking for the owner, Ian. Is she here?"

"Yeah, she's in the back room. One second." Ian leaned over the counter in front of Tim. "Mom!" he shouted obnoxiously, at the top of his lungs. Seconds later, a woman came out of the back room. She had long, blonde hair, and eyes as blue and piercing as Gibbs'.

"What's the matter, Ian?" she said as she approached. Gibbs and McGee held badges up for her.

"NCIS?"
"Naval Criminal Investigative Service, ma'am," Tim expanded. Gibbs glared at him and turned back to the pretty blonde in front of him.

"Lena Summers?" he asked.

"That's me! How can I help you boys?"

"Can we talk privately?" Gibbs asked.

"Sure, come on back to my office," Lena said with a smile. Gibbs and Tim followed her back to the tiny office. As they went in, Gibbs turned to McGee.

"Could you wait out here?"

Tim nodded. Gibbs went in and closed the door behind him.

"What's on your mind, Agent Gibbs?"

"We're investigating a murder of a Petty Officer," he said, taking a picture from the file he was holding. "His name is Jason Carney."

"What does this have to do with me?" Lena asked as she looked at the picture.

"We found your fingerprints on the victim's uniform."
Lena studied Gibbs for a moment. She had a glare that would rival his own. She looked back at the picture, and finally handed it to Gibbs.

"He came in here not too long ago. He was picking up an order for six boutonnieres. I remembered seeing his uniform and wondering how he could get along with it being in shambles like it was."

"His uniform was damaged?" Gibbs asked.

"His coat was torn badly. I felt bad for him, so I offered to sew the rip. That's probably how you found my prints."

Gibbs scribbled some notes in his pad.

"Anyone else in the shop that day?"

"Just me and my son."

"If you are all right with it, I'm going to have Agent McGee come in and take a swab for DNA, so we can rule everyone out."

"You don't think I—"

"It's just a precaution, ma'am. Nothing to worry about."

"All right, you can do it."

Gibbs nodded and left the office. Tim was waiting for him outside the office.

"Get a DNA swab from Ms. Summers and meet me out front."

With that he headed out to the front of the shop. The kid had resumed his position, headphones and all. Gibbs shook his head. He noticed an empty glass sitting on the glass countertop. Gibbs casually leaned on the counter. Sliding a fresh swab from his pocket, he broke the plastic wrap on it and traced the rim of the glass. He quickly sealed the sample and put it back in his pocket. Thankfully, the kid didn't notice. Seconds later, Tim came running out. Lena was at his heels.

"Get out of my store! Now! Both of you!"

Gibbs grabbed Tim by the arm and practically dragged him out the door.

"What in the hell happened in there?" He asked.

"All I did was take a DNA sample, I swear!" Tim said defensively.

"Spit it out, now."
"She started accusing me of trying to cop a feel when I leaned over to take the swab. I tried to tell her I didn't, but she wouldn't listen."

Gibbs rolled his eyes.
"For the love of… how do you manage to get into so much trouble, McGee?"

"I've probably been hanging out with Tony too much," he said with a smirk. "Boss, if she's not your sister, I'll be shocked."

"We'll let the DNA decide. Let's get these samples back to Abby."

"Samples?"
Gibbs took the sample from his pocket.

"From the kid."

Tim took it and bagged it, and they left.

"Can't this thing go any faster, Abby?" Gibbs said impatiently as the DNA samples ran through one of Abby's machines. He'd sent Tim back up to his desk, after swearing him to secrecy about the afternoon's events.

"Don't rush perfection!" Abby said, watching the test as it ran. It finally beeped, and Abby jumped out of her chair. "It's done!"

Gibbs joined her at the computer as she analyzed it.

"Well?"

"The DNA you took from Lena has one allele in common with yours. She's your half-sister."

Gibbs stared at the results on the screen. How could this be possible?

"D-Do either of those samples match the DNA on the body?"

"The DNA from the body came back as a perfect match to Ian Summers. Your nephew."

Gibbs fell onto the stool behind him. Not only did he have to go and tell a woman that he was her long-lost brother, but he also would have to arrest his nephew for suspicion of murder.

This case is blown to hell.
