A/N: Idea for this came from SyberiaWinx. So, if you don't like it ... go and yell at her. XD Joking. Yell at me too. She's not the only one to blame because I liked the idea and I wrote it. So there.

Alan was about to leave with his milk when Don walked in, complaining under his breath. "Donnie?"

Don looked up, "Gas prices are too high!" He growled, as he laid three twenty dollar bills down for the cashier, "I may have to ask for a raise or get rid of the SUV." He collected his change.

Alan shook his head happily. "Come on, Don. Let's get Charlie home."

They walked out to the SUV together and Alan right away, looked back at Charlie.

Who appeared to be sleeping.

And he did not look comfortable.

Don looked back at Charlie when he got in, "Aw. Look'it sleeping beauty."

Alan glanced at his eldest, "Well, he does need his sleep."

Don started his vehicle. "I just hope he wakes up when we get home. I don't really feel like dragging him inside the house."

Alas, and to Don's vain, that's what they had to do. Charlie was out cold. So, when they brought him inside and put him on the couch, they both stared down at him, worried.

Don checked for a pulse and found a regular one.

Alan checked for any new injuries and found none.

They both stood back and watched him sleep.

"I can't believe he's still sleeping."

"Me neither." Alan replied with a sigh. He looked at his watch, "Well. It's 9 pm. I'm probably going to go to bed."

Don nodded, "Alright. I'll watch some TV then go to my old room."

"I'm glad that you're staying the night." Alan told his son.

"Well, I figured as it's Charlie's first night back and all ..." Don said nonchalantly.

Alan nodded as he went up the stairs, to his room.

Don looked at his sleeping brother on the couch. Maybe they should move him to his bed? No, tha'd to too hard. It was hard enough just getting the guy inside the house. Don grabbed a beer from the fridge and sat down, turning on the TV and turning the volume on low - he didn't want to wake Charlie.

After a few hours of TV watching, Don yawned and headed up to his room.

Don woke up to someone shaking him. He blinked and watched as his dad came into focus. "Dad?"

"Don! Don! Charlie's missing!"

Don shot up, "What? I left him on the couch last night!"

Alan paced Don's room. "I've check his room, the solarium, the garage, the back yard. Don. I'm afraid of what has happened to him."

Don got up, "I'll have a look around myself." He headed downstairs, in FBI-mode, afraid of what he was going to find.

But after he looked around the whole property, he found that Charlie had disappeared. And no clues were there at all.

Don picked up his cell phone and dialed Megan.

"Reeves."

"Megan. I need you're help again." Don told her, hurriedly.

"Charlie?"

"Yeah. We can't find him. We've looked over the whole area. I can't find any clues."

"Should I bring a team?" Megan asked, worried.

"Not right now. Just, get here as soon as you can."

"Alright. Be there in a few." She hung up her phone and made her way to Charlie's house. Hoping that he was alright. Wherever he was.

When she got there, she rushed in and had a look around herself. And she too, found no clues.

Don pounded the table, "God! Charlie was taken right under my nose! Again!"

"Don." Megan said, "We are not for sure that he was taken." She smiled, her eyes moving toward the ceiling of the hallway, "In fact. I heard a noise. I think I know where he might be."

Don stared at her, "What are you talking about?" He blinked at her and followed her gaze. He listened and smiled. "Megan. You're a genius."

"Like Charlie is? Or like a person who just found the genius?"

"Both." Don answered, smiling.

Alan looked from one Agent to the other, "I'm sorry. I don't-"

Don moved to the string that hung from the ceiling and pulled it down. A step ladder appeared where the string had been moments before.

"The attic? You think Charlie's in the attic?" Alan asked, confused.

Don nodded. "Yeah. I remember he used to go up there sometimes when we were younger. That was when you," He said, talking to his dad, "Had all your city planning stuff in the solarium and the garage was still a garage, with cars inside of it."

Alan nodded, "Yeah. I remember that."
And so, the three of them headed up into the attic.

Yep, Charlie was there, sitting on the floor, with his back to them.

Don sighed, relieved that his brother was safe. "Hey, Buddy." He said, starting to walk forward.

Charlie turned and smiled at Don, "Donnie!" Then, as if nothing had happened, he turned back around, humming a tune from a song that Don and Charlie learned when they were kids. Charlie sang out the last verse nice and clear, "Put it in the oven for Donnie and Me!"

Don wondered why Charlie was singing Patty Cake. He slowly walked forward, afraid of what he'd find, "Buddy?"

Charlie turned around again, smiling and carefully moving some of his curls out of his face. "Donnie?" He blinked up at his older brother who kept walking forward, slowly.

Don was finally able to see what Charlie had been working on, and he turned to Alan when he saw it, "Dad?" He took a breath, "Why do we have an Easy Bake Oven?"

Alan looked at his son, baffled. He walked up to see what Don was talking about. And there was Charlie, making some things with an Easy Bake Oven. He swallowed, "I-It was your mothers." He looked down at Charlie how was happily playing with some matchbox cars while his oven was cooking a cake of some sort.

Alan bent down to his son, "Charlie?"

"Daddy?" Charlie asked, looking up at his dad. Eyes big and trusting. Innocent.

Damn. What had happened to Charlie?

"Charlie?" Alan asked, trying to keep his voice calm, "What are you doing?"

"Making us all a cake. And playing with the cars." He shot a glance at Don, then back at Alan, "Don't tell Donnie that I accidentally broke his favorite car." His voice sounded like a childs.

Alan blinked at Charlie, tears threatening to spill.

Megan walked up to see what was going on.

Charlie heard the footsteps behind him and he turned and stared at her. "Megan!" He smiled. "Hiya!" He waved at her, before turning back to his cars, forgetting about the three of them. "Vroom. Vrooom. Vroooom."

The three of them moved away from Charlie, about three feet away. Don's throat was dry. "That's not Charlie..."

"Something must have set this off." Megan said, "Tell me what had happened since you left the hospital."

Don took a breath, "We were going home and I had to stop and get gas. Dad went in and got some milk. We left him alone for about a minute or two, when we came back ... he was asleep. And when we got home, he was still asleep. We drug him inside and put him on the couch. When I went to bed, he still hadn't woken up."

"But this morning he was gone and I couldn't find him." Alan said, monotone, in a sort of shock, "And then Don looked. Then Don called you."

Megan nodded, "Alright. Well, My guess is whatever set Charlie off happened at the gas station." Megan sighed, running her hand through her hair, "Let's find out what it is." She walked over to Charlie and bent down to him. "Charlie?"

He looked up, eyes wide with trust. "Megan?"

"What happened at the gas station? Can you tell me?"

Charlie's face scrunched up, thinking. His tongue stuck out, thinking. "Donnie and Daddy left after Donnie was complaining about the price of gas. So I looked and I saw the price."

"And how much was the gas, Charlie? Can you tell me?"

Charlie looked down at his hand, "I don't wanna. It's scary." His voice was small, frightened.

Megan sighed, "Can you tell me? Please, Charlie? For me, Donnie, and Daddy?"

Charlie moved slowly to another area of the attic and grabbed a long forgotten stuffed bear, Archimedes. Named after the guy worked with Pi. "Archie knows." He said, hugging the bear his chest. "Archie and I share a secret."

"What is that secret, Charlie?"

"Pi."

"Pi?"

Charlie nodded, frightened, "Pi a-and 57.641592653589."

57.641592653589? That sounded familiar. "Megan." Don said, knowing what had happened, "That's the number that Charlie kept telling me when we first found him."

Megan nodded. "He brought it up when he spoke to me in private not that long ago."

Don nodded, "And the gas price. Guess what it was ..."

"I'm guessing $57.64."

Don nodded. "Something like that."

Megan sighed, "Charlie," Her whole attention back on him again, "After you looked at the price, what happened?"

Charlie looked down at the Easy Bake Oven.

"Buddy?" Don said, "Answer Megan."

Charlie took a deep breath, "Everything fell away n' I couldn't breath."

Don groaned, so ... Charlie didn't fall asleep, he passed out. "Oh, Charlie." His voice broke. His brother was having a lot of trouble with coping.

"Can Archie and I go back to playing?" Charlie asked.

Don nodded, biting his lip. "Yeah, Buddy."

Charlie smiled and went back to his playing with toys.

Don rubbed his forehead.

"You need to call Dr. Roland." Megan advised. "This is serious."

"Yeah. Like I didn't know that already when I found my baby brother playing with an oven, cars, and his toy bear!"

"Calm down, Don." Alan scolded, "What do you think would happen if he hears you yelling?"

Don sighed, he didn't know what would happen. Would Charlie get worse?

"He has seemed to revert back to being a child of some sort." Megan said, "He still remembers what happens and who everyone is, or so it seems." She looked at her watch, "I'm sorry. But I do have to go. And I don't know what I can do to help Charlie right now. Like I said, you need to call Dr. Roland."

Alan nodded, "Thank you, Megan."

"It's no problem. I'll check back later tonight and see how everything is going."

"We appreciate it." Alan said, turning to Don, "Stay with him. I'm going to call Dr. Roland."

Don sighed as he watched the two leave the attic. He walked over to Charlie. "Hey, Buddy?" His voice almost gave out.

Charlie looked up, "Do you wanna play with me, Donnie?"

Don could feel his heart break, "Y-Yeah, Buddy. I'd love to." He paused, "But let's not play up here, alright? We can take some toys with us downstairs."

Charlie thought about this, his lips pursing, "Alright. Donnie. If you say so." He got up and grabbed a few of his cars as he clutched Archie. "I love you, Donnie!" he grinned.

Don forced a smile, "I love you too, Buddy."
