Disclaimer - I don't own CSI.

N/A: I just wanted to say thank you to the people who have reviewed and to clarify that yes I know 'a red hair' isn't really something that would spark a break up but as the story develops other things and other reasons will, hopefully, become clear. Oh and by the way, Nicky didn't cheat and never will! So here's the next chapter, it's from Nick's POV so I hope no one gets confused. Love you all for reading xxx enjoy!

Greggo Knows Best

I turned the radio up, to block the sound of the thoughts aching in my head. Why didn't Sara believe me? I would never have cheated on her, not only because I love her but because I would never want to hurt her; she's been hurt before, why would I put her through that again?

I kept my eyes glued to the road and tried to stay focused on the task in hand, getting to Greg's house in one piece. If I started thinking about anything but that, Ava's disappointed face was all I could picture in my mind. A 10 year old being disappointed in me, broke my heart.

The roads seemed endless. Finally I saw the sigh for Greg's street just ahead. My mind raced more as I pulled into his driveway. Greg was going to have so many questions, I wasn't sure if I was ready to answer them, probably because I didn't have the answer to half of them myself.

I took deep breaths as I rang the doorbell, my bag of belongings at my side.

"Oh, Nick. What are you doing here?" Greg asked me as he opened the door.

"What, no hello?"

"Right, sorry. Hello," he smiled sleepily.

"I didn't wake you, did I?" I asked.

"No, I was just watching the game, I recorded it last night," he said. "Is everything ok? You look a bit, teary."

I sighed and stared off into space.

"You and Sara had a fight?" he asked.

"Yep. And she sent me packing," I said.

"Really? What did you do?"

"Nothing, but she thinks I cheated on her," I said sadly.

"Oh Nick," Greg said sympathetically.

"Is it ok if I stay with you for a while? Just till all of this blows over," I asked.

"Of course, you don't even need to ask, you know you can stay," he smiled as he opened the door wider for me to come in.

"Thanks man," I smiled back.

I entered Greg's warm home and made myself comfy on his sofa. I liked Greg's house, but it was massive for just one person. It was going to be strange living with Greggo for a few days. That was all I hoped it would be, but I would suck it up if it meant Sara would forgive me and let me home. I didn't even know what I had supposedly done, so how could I be sorry? But maybe she would realise she was wrong. I had to stay positive.

"You're probably gonna hate me but I have to ask. Honestly, have you had an affair?" Greg asked, his voice firmer than before.

"I swear on my life, I did not cheat. I haven't even looked at another women since I've been with Sara," I said.

Greg gave me a 'oh really' look.

"Well you know what I mean."

"Ok, I believe you but my opinion doesn't count, do you think she'll believe you?" he asked.

"I hope she'll see sense but I just don't know, no one, not even me can read Sara's mind," I smiled.

"I guess you're right," he said.

"I hope I'm right," I chuckled softly.

"So do you want to watch the rest of the game with me?" Greg asked.

"Nah, I think I'll just go get some sleep, if that's ok?" I said.

"Yeah, sure. You know where the spare room is, don't you?" he asked.

"Which one?" I joked. "Yeah. Thanks again Greggo."

"Heck, it's what I'm here for," he shrugged a shoulder.

"Enjoy the game," I said as I headed for the spare room.

"I will if you don't snore," Greg laughed.

"Me, snore?" I joked.

I disappeared into the room before Greg could reply. I was so tried. I got changed and tried to refold some of my crumpled clothes before collapsing on the bed and falling asleep.

A few hours later:

"You in there?" Greg asked as I zombie walked into the kitchen.

"Yeah, sorry," I yawned.

"Hungry?" he asked.

"A little bit," I replied as I stretched my arms above my head.

"Well I don't know if I can make pancakes like Sara does but I can give it a try, if you want?" he smiled.

"No, it's ok," I smirked.

"What then?" he asked.

"We could go out and get something?" I suggested.

"What, like on a date?" Greg asked as he wiggled his eyebrows.

"No," I gave a simple answer.

"Good, Sara would be heart broken," he smiled.

I rolled my eyes.

"I could order a take away?" he offered.

"At lunch time?" I asked.

"Yeah, we used to do it all the time," he smiled as he walked to the pin board and picked up the take away menu's. "Pizza or kebab?"

"Pizza, I'm not in the mood for complicated foods," I yawed.

"Pizza it is," he smiled.

"It's on me though," I said.

"No it's not, you're my guest."

"That invited himself. Honestly, I've got it," I said.

"Well in that case I'll have 3 of everything," he smiled.

"I don't think so," I said as I snatched the menus from him.

We ordered our pizza's and they arrived quicker than either of us expected. We both must have also been hungrier than we thought 'cause they didn't last long. Greg went channel surfing for something interesting to watch. There wasn't much. We ended up watching a forensics documentary and learning how we apparently should have been collecting evidence. Basically, it was pure bullshit!

"You ok?" Greg asked, looking very content with his full stomach.

"No, not really," I sighed.

"Sara?" he asked.

"The burden of my life," I smiled.

"Yeah but you love her anyway."

"I know," I sighed again.

"I hope you two will be able to sort this out," he said.

"So do I," I said.

"What else is on your mind?" Greg asked.

"Nothing," I lied.

"Nick, you can't lie to save your life," he smiled.

I laughed, although it really wasn't that funny.

"I'm being serious, you can talk to me," he said.

"I know but I don't know where to start," I said.

"The beginning?" he suggested.

"You sound like Sara," I smiled.

"Thanks," he said. "Wait, I sound like a girl?"

"No. It's just something she would say," I replied.

"Good," he smiled.

"She was right you know," I said.

"Right about what?" he asked.

"About the fact that I never talk to her or tell her anything," I said sadly.

"I bet you do," he said.

"Well then Greggo, you would have lost that bet," I smiled.

"Good thing I'm not a betting man," he joked.

I sat in the awkward silence just thinking and staring off into space again. I was gonna tell him everything with proper detail. Well, maybe not everything but the stuff that mattered at that moment. I hoped he was ready for all the new information he was about to get and that he could cope and understand.

I gulped hard as sentences formed in my brain.

"It was a mistake," I said softly and suddenly.

"What was a mistake?" Greg asked.

"Everything."

"Everything can't have been a mistake, no one can make that many mistakes," he stated.

"Well I can," I said.

"Nick, you're not making any sense. What was a mistake?" he asked again.

"This, me and Sar," I scuffed.

"You've lost me again," he smiled.

"I don't know what kind of picture you guys have painted but I'm sure as hell it's nothing like what really happened," I said in a slightly angry voice.

"Nick, calm down. Start from the beginning," he said.

I sighed. It wasn't making any sense. I wished it would. I wished I could just say everything, just not care and tell him what I had been bottling up for years. I knew I should have told someone everything now that I had someone who cared and someone I could actually tell. But Greg was gonna have to do.

"Ava was a mistake," I said.

"Ava? What do you mean Ava was a mistake?" he asked.

"Exactly that," I said. "She wasn't planned, none of this was. We were drunk. I thought we were ok even though she left but then when I found out she was pregnant… maybe I just should have let her go and get her life like she said."

Greg was clearly taken aback by this revelation. He sat there, frozen to the spot with his jaw on the floor.

"Greg?" I asked after 2 minutes when he still hadn't moved.

"Errrr," he said. "Just a bit shocked."

"Sorry," I smiled.

"Well, now that you've mentioned it, I don't actually think we thought that much about it, well I didn't anyway," he said.

"I don't believe that," I said.

"Maybe we speculated that Sara's pregnancy wasn't planned but she never thought that it was a one night stand."

"Well now you have more gossip to tell the others," I sighed.

"I'm a changed man Nick, I never gossip," he smiled.

"I'm glad," I said sleepily.

"You tired?" he asked.

"Yeah. You working tonight as well?" I asked.

"Uh-huh, I might get some sleep too," he said. "Oh no."

"What?"

"Sara's working too," he said.

"Oh, right," I sulked.

"I think Hodges is looking after the kids," he attempted a smile.

"That doesn't help," I said.

"I'm sorry," he said.

"It's not your fault, Greg. We're just going to have to stay professional," I said.

"Do you want me to tell Grissom to have you work with me?" he asked.

"Nah, I'll tell him," I said.

I was really quite proud of Greg. He had really grown up since Ava was born. I had thought it was 'cause he was an uncle now but maybe he grew up 'cause we did. Whatever the reason for Greg's maturity I was glad I could call him my friend.

"Off to bed," he nodded.

"Greggo knows best."
