So yes, this is a Nick and Greg story. Don't like, don't read. And sadly, I do not own anything.

It was a beautiful day in Las Vegas. Well beautiful in the sense that the weather was perfect for the current fall day, and Greg had the day off. He was only slightly aggravated that Nick had to be in court on the one day they both should have had off together. He refused, however, to lose his good spirits and instead took his day off to visit a crappy coffee stand in the down town park.

Greg was reaching for his coffee when he felt someone small collide with his legs. He looked down to find bright blue eyes staring back at him.

"Mr." The man at the kiosk said impatiently trying to get Greg out of the way for the next person. Greg grabbed his cup and stepped off to the side. The boy stepped over with him and Greg looked around. No one looked like they were looking for a child; he knelt down next to the boy, "Hey there." He said. "My name is Greg. Are your mommy and daddy here?" The boy said nothing to him. "Look at this." He said taking his badge off his belt. "I'm a police officer." Greg said trying to get him to talk.

The boy smiled and took the badge from Greg's hands but said nothing as he looked over it. Greg looked around once again for the boy's parents; He was only about four; there was no way someone wasn't looking for him. "Hey, you know my name, what's your name?" Greg said to him. The boy looked at him and leaned in a bit squinting his eyes and pursing his lips. Greg laughed at the expression. "You can't talk can you?" Greg said. The boy handed back his badge and when Greg was putting it back on his belt the little boy walked forward and grabbed hold of Gregs neck. Greg stood up and the small child curled right into him, burrowing his head into Greg's shoulder. "Alright kiddo. Let's go find out where your mom is."

They walked through the park and Greg kept his eyes peeled looking for any frantic parents. The small child kept laughing and looking up at Greg before putting his head back down to trace circles on Greg's shirt. "Oh Hi." He said to himself a few times. And Greg just smiled. The kid was adorable.

After roaming around the park for twenty minutes or so they sat down on a bench. "I guess I'm going to have to call you in little guy." Greg said pulling out his phone. The toddler reached for it and Greg let him take it. He looked it over a look of fascination on his face and Greg couldn't help but laugh. "You are really something kiddo." He said and put his hand out. The boy put the phone in Gregs hand and then leaned back against Greg sticking his thumb in his mouth.

Greg had just opened the phone to dial when a woman's voice caught his attention.

"Aidan Micheal Jones." The voice said sternly and Greg looked up to see a nun walking fast and a bit angrily towards him.

The boy in Gregs' arms giggled at her and turned into Greg more.

"I have been looking everywhere for you!" The older woman said. She looked at Greg and years of being in his job he could tell by the look on her face she was thinking the worst. Greg stood and pulled the boy, Aidan off of him and set him down on the bench.

"Hi, I'm Greg." He said to her. "The little guy here found me about a half hour ago. Good thing it was me too, I work with the LVPD crime unit; He could have gotten himself into some serious trouble."

Her face visibly lightened at his words. "Thank the Lord." She said. "I was so worried. I'm sister Meredith." She extended her hand towards him.

"He doesn't talk much does he?" Greg asked.

"Sadly no. Aidan is autistic and he struggles verbally. But put him in front of a mirror and he will talk his own ears off."

Greg laughed and turned slightly to Aidan who was attempting to lean on him from the bench. He turned back to her. "Are you his mother?"

"Oh heavens no child, I'm a nun." She laughed at him.

"Oh yeah; I guess that would make sense." Greg said mentally smacking himself.

"I work at the orphanage on Swede St. We take the kids out sometimes, Aidan needs more supervision than most and he slipped away."

"Orphanage? So he-"

She nodded finishing his sentence. "He has been with us for a year after his mother passed. Father was never in the picture as far as we know."

Aidan had managed to crawl onto Greg's back and Greg spun him around to his hip.

"Do you have children?" Sister Meredith asked.

"Me? Oh no." Greg said.

"Nice young guy like you? But you do so well with him." She said and He noticed she was looking at his ring, being his day off he had slipped it on that morning.

"Oh, my, uh, my husband and I aren't quite there yet." He said awkwardly. He waited for her reaction.

"Well I really mean it." She said smiling. "He has been with us for over a year and besides me; you are the only person he has let hold him without pitching a nasty fit. He really likes you."

Greg smiled looking down at Aidan whose big eyes were staring back up at him.

"Whatcha giggling about?" He said shaking him a little making him laugh more. Greg laughed for a bit, "Alright you, I think Sister Meredith might want to get back." He went to hand Aidan to the Nun, which proved to be a bad idea. The blood curtailing scream the child let out shocked them both. "Hey, it's alright." Greg held the boy to his shoulder, shushing him gently; he looked up at the Sister.

"Would you like to walk him back?" She offered. "It isn't far."

Greg looked up at her.

"Unless, you are busy?"

"No, I have the day." He said. "That would be nice."
