A/n, AU, teen Morgan and kid Reid with Rossi as their father. Hope you enjoy.

David Rossi sighed as he heard his two foster children chasing each other around his mansion. Derek Morgan was 14, and Spencer Reid was six years old. They had both came to him after he signed up to be a foster parent after he retired from the BAU. Spencer's mother was in a sanitarium so they could care for her and her mental illness and his father had walked out on them the year before. Derek's father had died when he was ten and his mother and two sisters were taken in a car accident two years ago. Neither boy had it easy, but Dave was relieved they were adjusting well at his house and with him.

"Hey, stop it!" came Derek's indignant voice. Sighing once again, he headed for the stairs and his feuding children.

Arriving at the elder boy's bedroom he saw Derek glaring at Spencer and Spencer arguing with him.

"What is going on here?" came Dave's stern voice.

"He took my book without asking and now he won't give it back," Derek explained.

"Spencer, why did you do that?"

"I was reading it then I put it down to use the bathroom but when I came back Derek had it and wouldn't give it to me.

"Did he ask you for it back and tell you he was reading it?" Dave asked, turning to his older foster son.

"Maybe, but he's too young for this book. It has a murder in it and it's kind of graphic," the dark-skinned boy declared.

"First of all, Spencer is a genius and is reading well above a first grade level. Second of all, where did you get this book, don't you think you might be a bit young for it as well?" the retired agent questioned.

"I don't know, maybe I am. I just wanted to know what kinds of things you did when you were in the bureau and I thought this book would help me do that," Derek answered.

"Why did you want to read it, Spencer?" Dave asked the younger boy.

"Because I'd read all the books that were on my book shelf and I was still bored."

"Ah, I see, well, Derek, this book is fiction and what I used to do is not, so how they will portray the crimes and solving them isn't always accurate. Spencer, if you want, we can go to the library and get you some more books later today or tomorrow. For now, I believe both of you have chores that you haven't finished, am I right?" the older man asked. Both boys nodded and headed to finish the chores they'd been given.

"Hey, what's this?" Derek teased as he came across a letter written on pink paper with a heart drawn on it on the living room floor next to the couch.

"Nothing, give it back!" Spencer cried chasing after his foster brother as he ran off with the paper.

"Spencer's got a girlfriend," he mocked.

"I do not, she's just my friend, now give it back," the younger boy hollered. He'd almost reached Derek. Reaching up as high as he could, he grabbed for the paper but missed and wound up falling over and crashing into a table. The table rocked and briefly appeared as if it would stay standing, but at the last second it toppled over causing the beautiful expensive vase on it to fall to the floor and shatter.

"Boys!" came Rossi's irritated voice as he ran to where he heard the crash. He'd been in his office working on his latest book. Skidding to a stop in the doorway to the living room, he frowned when he saw both boys staring forlornly at the broken vase.

"Somebody want to tell me what happened here?" he asked, placing his hands on his hips.

"Hey started it," both boys replied in unison.

"I don't care who started it, I'm finishing it. Both of you will clean this up then you'll go to your rooms until you can stop fighting with each other. Do I make myself clear?"

"Yes, sir," the mumbled shamefully.

"I have half a mind to fill your stockings with coal and make sure Santa knows you're names should be on the naughty list," Dave said exasperatedly. "Now, go get the broom and dustpan to clean this up then head on up to your rooms. I'll call you when dinner's ready," he instructed. Nodding both boys hurried off to do as they were told, all the while wondering if they would really be put on the naughty list and receive nothing but coal for Christmas. They really hoped not.

Finished!

A/n, a bit harder to write than I thought. This was given to me by another writer.
