I don't own Criminal Minds or characters.

Okay, this is my first try writing CM fanfic. There will probably some sort of slash couple later on, I'm not sure yet. I don't plan for this to have a romance but who knows. I know there are tons of kid Spencer fics but whats one more. There is mentioning of child sexual abuse and murder but it's not really talked about just a warning, might be talked about more later.

Spencer looked around his new bedroom. It didn't look at all like his old one. His mom had his room filled with books and writing tablets. The new one was filled with toys. He was surprised when his new daddy got him the doll that he had been looking at. His old one always wanted him to play sports and be outside all the time. His mommy said not to act smart in front of Daddy too much. But his new daddy didn't care how much he read, they even read the morning paper together.

There was only one rule for living with his new daddy.

Never talk about his old life, not to anyone.

It was hard not talking about his mommy, he missed her terribly. But he understood she was gone now. There were times he still cried at night thinking about his old family, but then Daddy would sing to him.

"Spencer!"

He ran out the bedroom door and down the hall. His new daddy was standing in the middle of their small kitchen.

"What do you want for breakfast?" his daddy asked.

"What can I have?" It was the same every morning. He hadn't been able to settle into their new life that well yet. When he lived with his mommy and old daddy he didn't always get food.

But it was all different now, his new daddy would make him anything he wanted, and if he didn't have it he would go out to get it. It still seemed like a dream that he got so lucky. He still missed his mommy and old daddy but his old daddy didn't want him. It was sad thinking about his mommy, his new daddy told him she got too sick. His mommy had died and he wasn't there. He cried all night when his new daddy told him. There were still nights he cried, but his daddy would bring him hot chocolate and he would sing or read to him. Now that he didn't have his mommy anymore he was glad he had his new daddy.

"Spencer, you can have anything you want remember?" His daddy smiling kindly at him.

"Waffles," he said, clapping his little hands with glee.

"Waffles it is. Strawberry syrup?"

"Yay," he cheered.

"Go get dressed, after breakfast we are going to the library. I have to go to work after that but Mrs. Carrington is going to take care of you."

Spencer didn't like when his daddy went to work, but he understood he needed to go. Mrs. Carrington was pretty nice, she was like what he thought a grandmother would be like. She made the best milk shakes.

"Can I get a lot of books?" he asked excitedly.

"Remember, for the books you like it's a ten book limit."

Spencer nodded. If it was the baby books he could get ten more than that but he liked bigger books.

"Are you going to get a book, Daddy?"

His daddy smiled wide down at him. "Maybe one, but that'll still leave you with nine to get." That sounded good to Spencer.

They had moved from motel to motel until they got to where they were going. As soon as Daddy saw Aquia Harbour, Virginia he knew they were at home. It was colder than he liked but he was getting used to it. At four years old he was better at adapting than his daddy.

"I have a surprise for you this weekend," his daddy said as he plated a waffle.

"What is it?" he asked excitedly.

"Where going to D.C. this weekend. You wanted to visit all the places you've read about, while we can't visit all we can try."

Spencer dug into his food with gusto. He'd lived with his new daddy for four months and loved him so much. But he missed his mommy very much, knew that dead meant dead. He was just glad she wasn't sad or sick anymore.

Aaron Hotchner, Unit Chief for the BAU, walked into the North Las Vegas Police Department. It was a large building; they were directed to the Investigative Command, led by Captain Coiler.

"Five dead kids, why are we just now being called in?" Morgan asked for the tenth time.

"I don't know, it seems very fishy to me," Rossi replied.

"Morgan, Rossi I want you two to go to the latest dump site. Prentiss, JJ I need you to help with interviewing the parents." Hotch called Garcia's phone.

"Yes, sir," she said somber. She had spent the last few hours looking over horrific pictures of dead children, all her cheer had been zapped out of her.

"Garcia, I need you to find any connections between the murdered boys. Add the missing boy to that."

"Got it, sir," she said before disconnected.

JJ and Prentiss sat in front of the three people on the couch. Hotch was interviewing the last boy's parents. They were interviewing the first murdered child's mother and the missing boy's father. They had been friends before the first murder, the missing boy's mother had recently been institutionalized. She had a major psychotic break after her four year old son went missing. Spencer Reid, four year old went missing from his front yard. His mother was having one of her episodes and little Spencer went outside to get away from the yelling.

At first the police thought that Spencer had been killed by his mother during the episode but it was quickly proven impossible. Mr. Reid had put in a security system inside the house to make sure that his wife had not been hurting their son during her episodes. The video shows little Spencer walk out the front door gripping a book. The mother didn't come down stairs until after her husband had come home.

All the murdered little boys were between the ages of four and seven. The first was Riley Jenkins, age six, sexually assaulted and stabbed to death. The second was Caleb Martin, age five, same M.O. Spencer Reid went missing next. Five little boys assaulted and stabbed to death over a five month period. There was no certain timing between the kills. It had been odd they hadn't been called in before now, someone had majorly dropped the ball.

"Mr. Reid, when was the last time you saw your son?" JJ asked, her voice gentle and caring.

"The day after his fourth birthday. I told him to take care of his mother before I left for work. That was the last time I saw him."

"Taking care of a mentally ill mother is a big job for a four year old," Emily said, she heard the accusing in her own voice.

"Spencer isn't like other kids, he's really smart. They have been after us to have him tested, I had been putting it off because I wanted him to be normal."

He must have noticed the look in their eyes at such a statement because it followed it up. "I mean I didn't want other people treating him differently." They had already heard enough, Spencer wasn't what his father wanted.

The questioning of Mrs. Jenkins went smoother. "One last question Mrs. Jenkins, where is Mr. Jenkins?" They had been unable to locate him.

Tears started running down the delicate woman's face. "He left a note, a few weeks after we buried Riley. It said he couldn't live in this world anymore. It was a suicide letter. The police should still have it, I gave it to them when we were looking for him. Right now he's an endangered missing person, but I know my husband, he won't be coming back."

It was four days later they had a lead. Gary Brendon Michaels, fit their profile perfectly. But that's when they ran into a wall, he was gone… in the dust. Now they had the name of their unsub but no unsub.

Spencer reached out and grabbed the book he had been eyeing. It was so big that he had to hold it in both of his arms. He needed his daddy to hold it for him; he looked around for him.

"Daddy," he called when he didn't see him. It wasn't like his daddy to not be there, he didn't like Spencer out of his sight. That was just fine with Spencer because he didn't like being around strangers.

"Daddy," he called again. He laid the book down and ran down the aisle. He was in the adult non-fiction section, where his daddy was supposed to be. His heart started beating wildly.

He ran up and down every one of the aisles in the area but couldn't find him. They were in a bookstore in D.C., he had begged his daddy to stop there. What if he got tired of him and his whining and left him there?

"Hey, kiddo, you lost?" a man asked him.

The man was funny looking, none of his clothes matched. That was okay for socks but this guy's clothes were all mismatched. The man had black rimmed glasses on, just a little less thick than his own glasses. The man seemed nice but Daddy said to never, ever talk to strangers. They were bad people and hurt little kids, he knew not all strangers but it was better not to take the risk.

"Spencer!" a panicked voice yelled.

Spencer turned to see his daddy running to him. He found himself scooped up into his daddy's arms and held tightly.

"Don't you ever wander off like that again," his daddy admonished.

"I'm sorry, I couldn't find you and got scared." He sniffled into his daddy's shoulder, trying not to cry.

"And you, what the hell were you trying to do with my son?" his daddy yelled at the man.

"Listen, I saw an upset and lost kid. I was just trying to help, next time keep an eye on him better," the man said darkly.

He watched the irate man stomp off with the little boy in his arms. The kid was a tiny thing with big, black rimmed glasses. He had never seen glasses bigger than his own, and on a little boy they were adorable.

"Hey, hot stuff," a cheery voice called to him. He turned around with a big smile on his face, the interaction with the man and his kid slipping away. All that was in his mind now was how lucky he had gotten to be with her.

"Hey, Pen," Kevin said brightly. "I thought you were working on a case?"

"I am, but even I can't live at Quantico," she laughed lightly.

"You can't?" he said, smiling.

"Oh, hush, I only have an hour to spend with my beloved before heading back to the abyss that I call my life." She walked out the door just in time to miss seeing the missing little boy, whose face was on her computer in her office, at that very moment.
