By the time Lindsay and Will had made it back to their building and Lindsay had gotten Will to stop talking about how cute Danny was, it had been kind of late. Lindsay smiled as she made her way to her bedroom and began pulling off her clothes. She had had a great time at Adam's tonight. Lindsay thought it was nice to be able to get out and be with her friends outside of the crime scenes and the lab.

As Lindsay pulled on a pair of striped pajama bottoms over her legs and then a tank top over her head, she thought back to the party and Flack. What had that been about? Flack had met Will before, about three weeks ago. What right did he have to tell her whom she could and couldn't share a cab with? God, Flack could be so weird sometimes.

Lindsay walked into her kitchen to grab a bottle of water before heading off to bed. As she listened to the plastic ring around the top of the bottle snap apart, her buzzer rang, announcing a guest outside. Lindsay flung open her door, ready to reprimand whoever was on the other side only to shake her head and smirk at the sight she saw.

Standing on the other side of her door was one of her favorite NYPD detectives. Flack was leaning against the door jam with his eyelids were half closed. He looked as if he was about to fall asleep or pass out standing right there in Lindsay's doorway.

"Flack?" Lindsay asked skeptically. Lindsay couldn't tell if she had turned his name into a question out of the need to ask why he was there or simply to make sure that he was still conscious.

Suddenly, in a slower movement than normal, Flack righted his body and stood up. He looked Lindsay in the eyes and turned up one side of his mouth lazily into a half smile.

"Can I come in?" Flack asked.

Without saying anything, Lindsay pushed her door open further and silently invited him in. Flack walked in and headed directly towards the couch, but stopped after a few steps.

"I'm sorry."

Lindsay turned to look at Flack. She saw his sincere, business-like look – one that usually only saw on the job. Taking a few seconds, Lindsay smiled warmly and looked up at him.

"For what?" Lindsay asked, honestly wanting to know.

"For tonight. I shouldn't have grabbed you. I shouldn't have yelled…"

"I don't think you yelled…" Lindsay interjected, but Flack didn't stop.

"… I shouldn't have done any of that." Flack finished, walked over to the couch and sank down onto with a thud.

"Flack, that was just you being… you." Lindsay said. "You just became a little crazed with it."

"Crazy is as crazy does." Flack muttered.

"All right, Forest Gump," Lindsay said sarcastically. Lindsay was going to ask Flack something else, but he continued talking.

"Going home with random guys isn't the smartest thing…" Lindsay could tell from Flack's speech that on top of everything else, that he was drunk.

"You know, Flack, he wasn't a random guy. Will's my neighbor. You've met him before, remember?" Lindsay's voice had taken on a new tone. She was annoyed that Flack had stumbled into her apartment, drunk, to continue the craziness from earlier at Adam's.

"Will? Will…" It seemed to Lindsay that Flack believed if he said the name enough, something would come to him. "Will… Will… Will? The interior designer? The gay guy?"

There it was. There was the recognition. Flack knew that he had looked familiar. He had met him, about two and a half weeks ago over at Lindsay's before they had met up with Danny for dinner one night. Will. Oh, Will. Flack realized that he had been jealous. He had been jealous of a gay guy. He had been jealous of a gay guy that Lindsay had introduced him to before.

"Sorry. It never clicked. Danny said that you're too trusting and that you've had problems with the guys from around here. I didn't want to see you get hurt. I may have been jealous…" Flack said from the couch. His voice trailed off at the end.

Lindsay had walked back into the kitchen to get Flack a bottle of water that she knew he would need. The word "jealous" got her attention. Lindsay froze for just a moment, a second or two really, to make sure that she had heard Flack right. As she walked over to the couch, she started talking.

"Danny Messer needs to figure out when to keep his mouth shut…"

Lindsay realized that this was the end of the conversation for the night. Flack's whole body had tipped sideways. He was asleep, his head resting on the arm of the couch and a light snore resonating from his chest. Lindsay smiled as she put his bottle of water down on the coffee table. She carefully pulled off his shoes and lugged Flack's legs up onto the couch. He didn't look incredibly comfortable, but he could take care of that himself – Lindsay knew enough about dead weight to know that she couldn't reposition this body. Picking up her own bottle of water, Lindsay made her way into her bedroom, turning off the lights as she went.

Flack moaned and rubbed his forehead, trying to make the ringing go away. It was about that time that Flack realized the ringing wasn't in his head, it was coming from the coffee table next to him. He was in the middle of wondering why he was on a couch and whose coffee table he was next to, when it occurred to him that he should answer his phone.

"Hello?" Flack asked with a scratchy, sleepy voice.

"Yo, sleeping beauty! Time to wake up. You gotta be at work in an hour."

"Messer?" Flack asked. He pushed a fluffy comforter off of his chest and sat up to look around. "Danny, why are you calling me?"

"Lindsay had to leave for an early call out this morning and didn't want to wake you up. She's out in the field right now, so I'm calling to make sure that you get your butt up off her couch, take a shower and get to work." Danny explained. Flack swore he could hear Danny's low chuckle on the other side of the phone. "So how drunk were you last night if you ended up on Lindsay's doorstep?"

"Whatever, man. I'll see you around." Flack flipped his phone closed and stretched to get the kinks out of his body. The night before trickled back into his mind. Flack had about an hour before he needed to be at work, and he needed a shower and some new clothes before work could happen. It was then, that a note tucked between his shoes caught his eye.

Flack –

Hope you slept well. You can leave the blanket on the couch. Here's a key to the apartment so you can lock up when you leave. Just give it back when we see each other at work. Help yourself to anything in the kitchen…there's water in the fridge. You might need it.

Lindsay

Flack smiled as he slipped on his shoes and slipped the note into his pants pocket. Grabbing a bottle of water from the refrigerator, Flack headed out the door and made sure to lock up as he left.
