Disclaimer: I do not own the CSI:NY characters, but if I did Mac and Stella would be together. Wow I've said that line a lot.

Notes: Okay so Mac and Stella are mad at each other. Will they be able to solve this? So I found the perfect song for this chapter It's called Do You Know? (The Ping Pong Song) by Enrique Iglesias. It fits this chapter perfectly.

Chapter 7

(Do You Know? (The Ping Pong Song) by Enrique Iglesias)

Do you know? Do you know?

Do you know what it feels like loving someone that's in a rush to throw you away?

Do you know, do you know, do you know, do ya

Do you know what it feels like to be the last one to know the lock on the door has changed?

If birds flying south is a sign of changes

At least you can predict this every year

Love, you never know the minute it ends suddenly

I can't get it to speak

Maybe if I knew all the things it took to save us

I could fix the pain that bleeds inside of me

Look in your eyes to see something about me

I'm standing on the edge and I don't know what else to give.

Do you know what it feels like loving someone that's in a rush to throw you away?

Do you know, do you know, do you know, do ya

Do you know what it feels like to be the last one to know the lock on the door has changed?

Mac was sitting at his desk staring at the door. He was glassy eyed. He was desperately wishing he could go back in time and stop himself from yelling at Stella. Mac should have known that there was no turning back when he went to confront her. How was he supposed to know that this would be the result? No, Mac, there is no one to blame but yourself he told himself over and over again.

"Mac," Lindsay came into the office with Danny.

"Huh?" Mac snapped out of his daze.

"Did you even go home last night?" Lindsay asked.

"No, what time is it?" He inquired yawning.

"10 a.m." Lindsay replied. Mac looked at his clock to double check. Sure enough he had spent the night in his office just thinking. Mac shrugged. It didn't exactly register with him. Out of the corner of his eye he saw Stella come in to the lab. He sighed. She didn't even glance at him when she walked by.

"Mac, did you hear what we just said?" Danny asked.

"What?" Mac wasn't paying attention. His focus was on Stella who was walking to the break room.

"Mac, go home. We can deal with things at the lab," Lindsay told him. Mac gave her a look.

"No, I'm fine. And for the record, I don't trust the lab with you two," Mac smirked. He went to the trace lab. Stella would be in DNA, and she wouldn't have to deal with him. He put on a lab coat.

"Mac, what are you doing in here?" Adam asked. He was coming in with Kendall. They were laughing about something.

"Running some trace," Mac replied concentrating on his work. Kendall left the trace lab to help Stella with DNA. Adam wasn't used to having anyone working with him in the trace lab. Mac was finished with the trace and was trying to find out what it was.

"Adam, do me a favor and tell me when that's done," Mac ordered as he took off his lab coat and gloves. Mac left for the break room for some coffee.

"Okay will do," Adam replied looking up to find Mac gone. He shrugged and put his headphones in. He started listening to Running up That Hill by Placebo. After that song was over he listened to Hey There Delilah by the Plain White T's. Mac finally came back during Love Song by Sara Bareilles. Adam was singing along.

"Blank stares at blank pages. No easy way to say this. You mean well, but you make this hard on me. I'm not going write you a love song cause you ask for it. Cause you need one you see. I'm not going to write you a love song cause you tell me it's make or break in this if you're on your way. I'm not going to write you to stay," Adam sung. Mac was trying to keep a straight face.

"That's okay Adam. I just wanted the trace results not a love song," Mac told him. Adam was horrified. He turned around to Mac laughing.

"Mac, I didn't know that you were standing there," Adam was so embarrassed.

"I was serious. Do you have the trace results?" Mac asked.

"Yeah. It's carpet cleaner. Totally generic. Sorry that it wasn't more," Adam handed the trace results to Mac.

"Thanks," Mac said as he walked off. He had the case file in his right hand and the trace report in his left. He was placing the trace report in the file. Mac went to the DNA lab to find out whose DNA was under the victim's nails.

"Kendall, do you have the DNA on the Raft case?" Mac asked walking into the lab. He was looking at the case file.

"Yeah, still no hit in CODIS," Kendall replied. Mac sighed. Stella was working on a different case.

"Can you tell Stella that I'm sorry and that I over reacted?" Mac asked. Kendall told him she would. He left for his office. He wondered if Kendall would actually tell Stella that he was sorry. He knew that he had made a huge mistake. Mac didn't know if he would ever be able to right his wrong. He thought about going up to Stella saying," I'm sorry. I got onto you because I love you." That thought lasted all of one second. The second idea was worse. At last he just gave up. Mac didn't know how or even if they were going to make up. Shift was almost over, and Mac was tired. He hadn't slept in two days.

"Hey Mac, we are going to grab some beers when shift ends. Do you want to join us?" Hawkes was trying to get Mac out of the lab.

"I'm going to take a rain check. I have got to get home," Mac told him as he got his suit jacket off of his coat hook in his office. He put it on as he left the lab. When Mac got home, he crashed on his couch. He woke up the next morning to his preset alarm. Regardless to how he felt, Mac went through his morning routine. When he got to the lab, he was early, but then when was he not early. Mac got his coffee, and went to the trace lab where he began to run trace on some cold cases. Nothing new to specify them. Mac slammed his fist down. He was bothered by this, but that wasn't the only reason for his anger. Why couldn't Stella forgive him?

"Whatever," he mumbled. He put the trace evidence in its rightful box. Mac then put up the case files in the basement. When he got back up to his office, it was still 30 minutes till the start of shift. No one was in the lab. It was a kind of eerie situation that would bug a rookie, but not Mac. He found the silence a great place to think about what was troubling him.

"Whoa Mac. Two days in a row we find you in your office at the start of shift. How long have you been here?" Danny asked from the open door of the office.

"I don't know," Mac answered truthfully. Then a miracle happened. Flack called with a crime scene.

"Danny, Lindsay, get your kits ready we have a scene," Mac told them.

"Where at?" Danny asked.

"5th Avenue and 22nd Street," Mac replied getting his coat. It was a chilly day. The CSI's left for the scene.

"So this is how the super rich live," Danny said as he glimpsed the apartment crime scene.

"Well if this is how they die then I would rather stay poor," Lindsay stated looking at the gruesome homicide.

"Flack, who is our victim?" Mac asked the detective.

"James Montgomery. Where is Stella?" Flack didn't know about the fight.

"Wasn't in the lab when you called with the scene," Mac started processing around the body. Lindsay took the perimeter, and Danny took the bedroom.

"I asked for you to call her to come," Flack had no idea that Mac had no intention of calling Stella. He thought that it had just slipped Mac's mind.

"If you want her here then call her yourself," Mac fiercely said as he continued to process.

"Whoa, what happened to you two?" Flack asked, but Mac ignored him. He was busy photographing, bagging, and tagging. It would have been nice having another CSI around to photograph. Mac wasn't going to admit it though. After 9 hours of processing, the CSI's went back to the lab. Mac dropped off the trace for Adam to run. He dropped off some DNA for Kendall who was in the DNA lab again. Mac went up to autopsy.

"I was wondering when you were coming up here," Sid said as Mac entered.

"Well I'm here. What's the official COD?" Mac asked.

"Blunt force trauma," Sid replied.

"Okay if it was only blunt force trauma you would just send me the report. What else is there?" Mac questioned.

"Well actually I do," Sid was flattered. Mac rolled his eyes.

"I have finger prints around the wound. I already sent them to the print lab. They came back Grant Jacobs," Sid said handing the autopsy report to Mac. Mac called Flack and told him to pick this guy up. Three hours later, Mac was interrogating him.

"Grant, we found your prints on the victim," Mac told the suspect. The suspect was shaking and had several needle marks in his arm. Mac thought that the killing might have been drug- related.

"I never touched James," Grant said.

"Really? Because we found your prints on James and on the murder weapon," Mac showed him the picture of his prints on the murder weapon.

"That doesn't mean I killed him. What motive would I have?" Grant asked.

"Judging by your shaking and the needle marks in your arm, I would say you were looking for the next high. Maybe James was tired of funding your drugs," Mac told him.

"That wasn't how it went down. James was my dealer. He wouldn't give me the drugs after I paid him," Grant said realizing he was caught for drugs.

"We found drugs on you," Mac wasn't sure whether or not he believed this Grant Jacobs.

"That's because I took them after I killed him," Grant had the last word. The officer in the room arrested him.

"Mac, that was so easy. He just confessed," Flack was enjoying this short case.

"Yeah, it's weird though. Normally people aren't that willing to confess. Anyways we still have to run that DNA under James' fingernails against Grant's DNA," Mac told him. He wasn't sure if Grant had actually killed James.
