Greg yawned as he entered the staff room. He had been up late the previous night and had been working non-stop since he arrived at work this morning. Before he could even reach the sofa and crash out for ten minutes, Nick stepped into the room also and smiled brightly by means of greeting.
"Hey! What're you doing here on your own?"
"Looks like I'm not on my own any more, am I?" Greg replied, yawning again.
Nick raised his eyebrows and shrugged before heading over to the fridge. "I guess not. What are you doing here with me, very not alone, then?"
"I was just taking a break. My brain hurts."
"Your brain hurts?" The dark-haired CSI repeated, humour crossing his face.
"Yes!" Greg exclaimed, causing the other guy to jump slightly. "Have you any idea how much stress fingerprint analysis puts on the cerebral cortex?"
"You really need to get out more, lab-boy." Nick chuckled, taking a swig out of a carton of milk clearly marked "Grissom".
"AHA!" Greg exclaimed once again. Luckily Nick has lightening-fast reflexes, otherwise the milk would have been down his shirt instead of in his mouth.
"Jesus, Greg, will you stop doing that?"
"You're the mystery person who keeps stealing all of the milk!" Greg said, pointing an accusing finger at the CSI and then the carton of milk.
"I'm not stealing." Nick shrugged, taking another swig. "I'm borrowing."
"What're you going to do, regurgitate it back up later?"
As Nick held the carton up once more, Greg snatched it out of his hands. "Nick, quit it." he whined, putting the milk back into the fridge and standing against the door so it couldn't be opened. "I'm telling."
Nick rolled his eyes and reached into his pocket, pulling out five dollars. "Go buy some milk and don't tell Grissom."
"Maybe I want you to get in trouble." Greg tested playfully, crossing his arms and not taking the money. "It's a serious offence, haven't you seen the sign?"
Nick looked over towards one of the cabinets and smirked.
"Label your items and do not use anybody else's!"
"That sign's been there since before I started here. 'Sides, who pays attention to it anyway?"
"Me!" Greg said defensively, not planning on explaining the time when accidentally used Sara's last tea bag.
"You can't even tell that I've had any of the stuff, Greg. It's a carton of milk. He won't notice."
"Fine. But if he does happen to notice, I'm going to tell him it was you."
Nick still had the five dollars in his hand, so Greg smiled. "Can I have that as a bribe to not tell?"
"What?" He asked in confusion. When it clicked, he shook his head. "Oh. No. You wouldn't even tell him. Not with me knowing what you did in the locker room."
With that, Nick exited the room; leaving Greg mortified.
