Stella Bonasera sat at her desk, idly looking out of the window, thinking, just thinking. She did that a lot whenever she didn't have a case and when paperwork got boring, she'd just sit back in her chair, look out over the New York skyline and think.

"Oh, sorry Stella, didn't see you there. You haven't seen Lindsey about have you?"

She looked around, startled at the sound of Flack's voice and was even more startled by the bunch of flowers he had in his hand. She raised an eyebrow at him, her eyes telling him that she wanted an explanation.

Flack smiled slightly, a little sheepish at being caught red handed trying to deliver flowers to his fiancée.

He sank into Lindsey's chair, putting the flowers on the desk in front of him and looked at Stella who still had her eyebrow raised at him.

"Should I even have to ask what you are doing up here with a bunch of flowers looking for Lindsey, or do you just want me to guess?" she said at last, breaking the silence that had fallen between them as Flack had tried to find the right words to say to her.

Finally, he seemed to have decided that there was no other way to tell her, except for the truthful reason why he was up in the crime labs with flowers looking for Lindsey.

He sighed and sat further back in the chair.

"Lindsey and I are together. We had been dating for a year and a half, she moved in with me about 8 months ago," he paused slightly, but Stella jumped in first.

"Don't tell me you cocked it up did you?" Flack laughed slightly, shacking his head.

"Nah, we got engaged 2 months ago, and to celebrate our two month anniversary of being engaged we were going to go to the Opera, our wacky next door neighbour won tickets from his work, but he hates the Opera, so he gave them to us, thinking we could use them, but I've just been told that I have to work tonight, so I can't go,"

"So you bought the flowers to say sorry?" Stella guessed, trying to keep her expression neutral, which was hard after just finding out that two people you thought you knew like the back of your hand had secretly been dating for about a year and a half and you had never even guessed.

In fact, she had tried to push Lindsey into going out with Danny, what a fool she must have looked.

Flack nodded, looking at the bouquet he'd bought from the small florist around the corner from the precinct. Simple daisies and bittersweet mixed in with other wild flowers. Lindsey loved wild flowers, said they always reminded her of home.

Stella smiled at him as she watched him look at the flowers.

"Well, I'm happy for you, a little shocked that you managed to keep that from us for so long, but I really am happy for you guys."

Flack grinned at her, his blue eyes twinkling in the slowly dimming light coming through the large glass windows of the office.

"You think she'll forgive you?" she asked. Flack nodded.

"Yeah, I can look very remorseful when I need to." He said with a wink.

Then a thought flashed across his mind and the look in his eyes changed from playfulness to scheming and Stella didn't like the way those now dark blue eyes turned to her.

"Stel, would you mind if I asked you to take my place, you go to the Opera with her, keep her company?" Flack looked almost begging, the flowers held out in front of him like he was trying to talk to an ex-girlfriend he wanted back, but whom had no intention of seeing him.

Stella shock her head, pointing an accusing finger at him.

"No Flack. You remember the last time you asked me to keep one of your female friends company, I didn't know that you were planning on breaking up with her by not turning up and she spent the whole time crying on my shoulder."

Flack tried not to smirk at the memory of that. Yeah, it had been a cruel way of breaking up with the girl, but at least he hadn't been the one having to listen to her cry. Besides, Stella had come away unscathed, where as he would have ended up in a very bad situation.

"Stel, I'm not breaking up with her, so you don't have to worry about that, and I know you have a thing for Opera. Please Stel, this is the last favour I ask of you, other wise I have to ask Danny, and I really don't want him finding out about me and Lindsey and then asking him to sit through an Opera with her where she's in a stunning dress."

Stella looked into his blue eyes and let out a sigh of defeat. She had to admit that Flack did have a very good point. Danny would be hurt when he found out about Flack and Lindsey, plus Flack was making puppy eyes at her, which would guarantee that she would say yes.

"Alright Flack, I'll go with Lindsey."

Flack grinned and gently kissed her on the check before turning around, thinking about going to find Lindsey when he saw her stood in the doorway, leaning against the glass frame. She didn't look cross, but she had her arms folded across her chest.

"Sounds like you're trying to get out of our arrangement tonight." She said, stepping further into the room so that the glass door could swing closed behind her.

Flack shock his head, smiling at her.

"I'm not, I swear. My Caption has got me 'babysitting' one of the new cadets out of the academy, and I tried to get out of it, but he wouldn't listen, so I can't go, I'm so sorry." He held out the flowers, as though trying to say something by the gesture. Lindsey's face broke into a smile as she saw her favourite mixture of flowers and when she looked up at Flack, Stella saw pure love in the young woman's eyes, and pure love in his. Although it sounded very clichéd, you could tell that they were a perfect match.

"That's alright Don." She said quietly, taking the flowers from him. He grinned at her, and both women could see how hard he was fighting against the urge to stroke her check and kiss her.

"Do you want me to leave?" Stella asked, moving to get up from her desk.

Lindsey shock her head, turning to her.

"No, don't worry, he'll just have to keep it on ice until later." She said, winking at Flack, who grinned back, sitting on the edge of her desk. "So, you're coming to the Opera with me?" she asked as Stella sank back into her chair.

Stella nodded. She was starting to feel quite excited now. She hadn't been to the Opera in months. She just hadn't had the time, or the money, or a date to think about it. Ever since the thing with Frankie a few years ago, she hadn't had anyone to go with, or gotten the courage to ask anyone to go with her.

It would be nice to get out of the apartment for an evening, instead of just being sat on her couch watching stupid quiz shows on the telly.

Flack' pager went off, causing both women to look at him again. He smiled apologetically to them as he pulled his phone off his belt and read the message flashing across the screen.

He let out a sigh and clipped it back onto his belt.

"I have a call." He said, getting to his feet. "I'll see you tonight." He said, quickly kissing Lindsey on the top of her head. She nodded, smiling at him as he quickly hurried out of the office and towards the elevator down to the lower floors of the police building.

Lindsey turned her attention back to the office, a smile still tickling the corners of her mouth, her checks a little red, and her flowers still clenched in her hand.

Stella just grinned at her.

"I had no idea." She said at last, causing the younger CSI to look at her, a slight shrug touching her shoulders.

"We tried to hide it, I know Mac doesn't really like co-worker relationships, and well, we were going to tell you guys before the invitations came out, we just didn't really know how." She shrugged her shoulders a little, looking back at her bouquet of flowers.

"I'd better get these in water." She said, knowing that Stella was going to ask her everything about her relationship with Don, right from where they're first date was, to how he proposed, and whether he did it right.

Stella just smiled, she'd get the information from Lindsey later, ask her at the Opera, it would fill in the time during the interval and journey there and back.

Yeah, she was going to have a lot of fun getting every last bit of information out of Lindsey Monroe tonight, mark her words she would…
