In the Interrogation Room

Cos' you bring out the best in me,

Like no one else would do,

That's why I'm by your side,

That's why I love you.

A pair of legs strode down the hall in the New York Crime Lab while one hand belonging to that same body was holding a small piece of paper with a few names scribbled on it.

The other hand was ticking the names at top speed as the legs ran along past all the rooms.

"Ok… lab, Mac and Aiden, blush, check. Morgue… Stella, check," he mumbled as he scanned down the list and checked that everyone was busy with something or other.

Danny then went into the locker room, the only unoccupied room. He did not want anybody to know what he was up to.

Danny shot to his locker, opened the door and started rummaging through his belongings.

"Phew!" he sighed after pulling out a tiny velvet covered box that revealed a beautiful diamond ring when opened.

"I thought I would never see you again!" Danny cooed lovingly as he stroked the precious gem over and over again.

A second later, he stopped, suddenly realizing how stupid this must look.

Flack walked past the locker room but stopped dead in his tracks after he spotted the back of his colleague, Danny. Isn't he supposed to be running evidence right now?

As his eyes peered into the room, Flack caught a glint coming from Danny's hand, the kind of glint that comes from diamond rings…

Flack covered his mouth to stop him from laughing out loud. Wow, Messer. You really surprise me… wonder who's the lucky girl?

Flack thought of all the seemingly good possibilities that good cover up the fact that Mister I-am-so-shy-in-front-of-girls is going to propose.

A familiar question that bugged him since he was witness to a Danny and Aiden romance conversation a week ago had come and settled into Flack's memory again.

Then it hit him… It's Aiden! Should I tell Mac or not?

He suddenly heard footsteps echoing down the hall. Flack quickly walked off before Danny turns around.

Danny has also heard the footsteps and scrambled to keep the ring back in its box.

He managed to shove it into the box a split second before his boss, Mac came into the room.

After staring at each other a few seconds, Mac asked the most obvious question, "What are you doing in here, Danny?"

"Wha… oh… nothing sir. Just tidying up the mess in there…" replied Danny with his back to the locker and hands trying to hide the tiny box which houses three months worth of Danny's salary.

"Strange, you didn't strike me as a cleaning up kind of guy. Not with the name Messer, y'know?" Mac stated with a smirk.

"Err, well, names can be deceiving sometimes, Mac…" said Danny. Ok, why is it that everyone knows that joke?

"Haha… Anyway, see you around."

"Will do, Mac."

Mac went up to his own locker, took out a file and rushed back to the lab.

Once he was alone again, Danny took the box out. He had planned to keep it with him, for fear that someone would come snooping and steal it.

He was about to leave when he caught a look at his own reflection. He decided to try out an impromptu rehearsal. He heaved a big sigh and started reciting.

"Y'know what, Aid? I've been working with you for a long time and…" he paused, "Ok, relax… first time jitters… I'm fine…"

"Hey, Aiden," he drawled, making full use of his New York accent, "Would you… um… would…"

Danny rubbed his forehead in frustration and he accidentally lost his grip on the box and the ring so he scrambled to catch it.

It took him one great save and one microsecond before his salary went kapoof!

After catching the box, Danny straightened up, quite forgetting his locker door was still open. Naturally, Danny slammed, quite comically, face first into it.

"Oww…"

Danny cleared his throat and heaved another sigh, "Y'know what? I love you a lot… so… wouldyoumarry… uh… me?"

He wrinkled his nose and made a face. "If I were Aiden, I definitely won't say yes…"

Danny glanced at his watch, 6.00 in the evening. Bette get goin' before Mac thinks he's been abducted or something…

With one last look at the diamond ring, Danny snapped the box shut and shoved it into his jacket pocket.

He then strode out the door, determined not to tell anyone about the fiasco in the locker room.

Danny rounded a corner and bumped right into Aiden. "Where were you?" she demanded, a little annoyed, "You were supposed to get the DNA results from the knife, when you didn't get it, Chad paged me instead…"

Danny winced, "Oh yeah… I forgot…"

The whole team had been on this case for a week already. A women, stabbed to death, 25 times on her chest. There were a huge number of suspects including the grieving husband, brother, father and even the postman. With that much DNA to process, things had been moving quite slowly.

Aiden wrinkled her nose and said, "We got a match, Flack's bringing him in for interrogation now,"

She began adjusting Danny's jacket with her lips twitched sideways, "Honestly… presentation is important, y'know…"

Danny grinned, "Glad you're always around to help, then,"

Aiden rolled her eyes and said, "C'mon…"

"So, whose DNA was a match?"

"The blood on the blade, obviously the victim, the foreign blood? The husband. Must have cut himself,"

"The husband?" asked Danny, surprised. The guy seemed so pathetic that it was hard to believe he could kill…

"The husband," she replied affirmatively.

Together, they headed to the interrogation room.

When they entered, there was Flack leaning against the wall, staring at the husband of their victim, Sandra Mitchell.

Jack Mitchell's eyes were red from crying. "I don't understand what else you need… haven't I already told you all I know?"

Danny picked up from there, "Not really, Mr. Mitchell. You left out a few things. Things like why your DNA was found on the knife used to kill your wife…"

Mitchell looked shocked, "What? My DNA? My DNA was there?"

Flack said, "Don't play games with us, Mr. Mitchell. You see-"

A pager started ringing. Danny, Aiden and Flack all checked their pockets. Flack inclined his head to tell the others it was his.

After a moment, he said, "I gotta go for a sec, you guys ok taking it from here?"

Danny and Aiden both nodded. With that, Flack went out. Danny wondered a little why Flack looked a little strange just now when Danny and Aiden came in. Half surprised, half nervous…

Shrugging it off, Danny continued, "That's right, your DNA was there, which would mean your blood was there. The only way your blood will be there is if you cut yourself during your frenzy of cutting up your own wife,"

Mitchell looked at them both indignantly for a moment, then his lips quivered, and he broke down completely.

"I didn't mean it… I really didn't!" he sobbed, covering his face in his hands, "I mean, how would you like it, if your wife was barking at ya' all day, all night. Always complaining bout' the laundry, the bills, the cleaning. I lost my temper, ok? I had enough of her squawking… I grabbed a knife and... and…"

Both Danny and Aiden were a little taken aback by this sudden confession. Aiden nodded to the police officer by the side to take the sobbing Mitchell away.

At the same time, Flack made his way to Mac's office. Mac and Stella were in there, discussing something.

Flack knocked on the door, "You paged?" he asked.

They both looked up. Mac nodded, "You said you wanted to talk to me about something earlier?"

Flack felt uncomfortable, "Did I?" he asked, knowing perfectly well he did.

At the spur of the moment, he had walked into Mac's office earlier to tell Mac about Danny and Aiden. But the phone rang before Flack could tell Mac about it.

When he was shooed out of the office, he had made up his mind to let Danny and Aiden let Mac know on their own and had hoped that Mac would have forgotten. Unfortunately, he did not.

"Yeah… you did… you said it was important?" said Mac with a frown. Stella was also looking at Flack questioningly.

Flack searched around for an excuse, "Uh… I'm supposed to be in an interrogation right now… I'll get back to you later, ok?"

Stella asked, "The Mitchell investigation?" Both Mac and Stella stood up.

"Why didn't you call us?" asked Mac, putting on his coat, "It sounded important when you said so earlier, let's talk on the way."

The two of them headed towards the interrogation room and Flack had no choice but to follow, "It's nothing, Mac, really…"

"I thought you said something about an office relationship in here?"

Damn! Flack had thought Mac didn't catch that. Wasn't he on the phone when Flack let that sentence slip?

Stella's eyes widened, "Office relationship? Really?"

They went into the room adjacent to the interrogation room, containing the two-way mirror. Through it, they saw only Danny and Aiden.

"Oh, they've wrapped it up already," said Mac.

He and Stella were about to leave when Danny's words brought the three to a halt.

Once the office left the room with Mitchell, Danny put a hand into the pocket containing the precious diamond ring, should he ask now?

Aiden was shaking her head with her back to Danny, "I can't believe that guy. Killing his wife over a petty thing like that. Stupid…. She shouldn't have died at all…"

A heated debate was starting in Danny's mind now and he barely heard what Aiden said.

His fingers brushed against the velvet covered box, his heart starting a war dance-like rhythm.

'Now, now, now!' one part of his head was screaming. 'No, no, no!' the other part yelled equally as loud.

Aiden, oblivious to Danny's frantic thoughts, was saying, "Crazy how sometimes a marriage can go wrong, huh, Danny?"

"Well, I'm willing to take that chance," mumbled Danny.

The words didn't quite register to Aiden at first.

Frowning, she turned to face Danny. Out of a sudden, Danny got down onto one knee, taking a small velvet box out of his jacket pocket at the same time.

He opened it to reveal the most beautiful diamond ring Aiden had ever seen, 'Ohmigod…'

Removing it from the box and taking Aiden's hand, Danny slipped the ring onto Aiden's trembling ring finger, 'Aiden Burn, will you marry me?"

(Behind the mirror, three jaws dropped to the lowest level possible, creating a new Guinness record for 'Lowest Jaw Drop'!)

Aiden let out a soft sound like a gasp and a laugh combined as Danny stood up.

Their eyes met and Aiden flung her arms around Danny, letting out another gasp/laugh.

After a moment, Danny pulled away a little, "Woah," as he stared into her eyes, "Does that mean 'yes'?"

Aiden all but screamed, "YES!"

Danny's heart felt at ease for once in days. Aiden sank into his arms again and they just stood there in each other's arms, savoring the peacefulness and their love for one another.

That's why I'm by your side,

That's why I love you…
