Christopher The Lost

Chapter 1. The Day Everything Changes

"Don't worry, daddy. I'll go tuck him in." Peter offered.

"Alright. I'll be there in a minute." Frank said.

Peter started dragging a very bouncy Christopther up to his room. "I'm not tired!" he exclaimed, fighting against his older brother.

Peter rolled his eyes and kept pulling him up the stairs. "Come on Chris, it's bedtime." he said.

After a bit of struggling Peter managed to get Chris into their room. "But Peter, I'm not... tired." Chris said around a yawn.

Peter got him up on the bed. "Really, cause that yawn tells me you are." he said. Chris yawned again and Peter raised an eyebrow, smirking, knowing Chris couldn't last too much longer.

Chris smiled and started jumping on the bed. "I told you I'm not tired!" he laughed.

Peter sighed and blew the hair out of his eyes. He then smirked at Chris.

"What are you looking at me like that for?" Chris asked.

Without an answer, Peter grabbed him and started tickling him, making Chris laugh his head off. Peter laughed too, his blue eys shining. He knew there was no doubt Chris would be tired soon.

Their dad walked in and starred at them a second. "Alright you two, when I said go to bed, I meant acctually sleep in the bed." he said.

"He won't sleep." Peter said. He had since stopped tickling Chris, but Chris was still laughing like Peter was still tickling him.

"Both of you, asleep, please." Frank said.

Chris stopped laughing and blinked a few times. Peter took the opportunity to pull them both under the blanket's. Chris huddled close to Peter, yawning again. "We have a winner." Frank mumbled.

Peter smiled and pulled his arms around Chris before closing his eyes. Frank smiled, and kissed them each on the top of the head before leaving the room.

A crash from upstairs caused Frank Pevensie to jump to his feet. The crash had come from Peter and Christopher's room. Chris's cry followed soon after.

"CHRIS!" Helen screamed.

Frank ran up the stairs, but by the time he got to the room, he was to late. His youngest son... was gone.

Peter came up beside him, from where he had been in the bathroom. "Daddy! Where's Chris?!" he exclaimed, eyes wide.

And when Frank look at the busted window he pulled his eldest son away from the room, closing the door. "He was kidnapped, Peter." he said as calmly as he could manage, so not too scare Peter further.

"Kidnapped?! You mean he's gone?!" Peter exclaimed.

"Yes, for now. But we're going to find him." Frank said.

Susan came out of her room, yawning. "What's going on? I heard Chris crying." she said.

Frank shook his head. "Go back to bed sweety, we're taking care of it." he said.

She yawned again, but didn't move. Peter walked over to her and led her back into her room, knowing their dad was right. As of now, there was nothing they could do.

A baby's cry echoed through the house.

"LUCY!" Frank exclaimed, jumping to his feet and running to his and his wife's room, where their newborn daughter's crib was, unsure of what was going to happen next. When he got there she was only crying for an unknown reason. He let out a sigh and walked over to her crib. He gently picked her up and she stopped crying. All she had wanted was someone to hold her. He smiled and held her close.

Helen walked in and stood beside him. He smiled at her, but a second later another crash echoed throughout the house, followed by Peter's cry of "DADDY!" and Susan's blood-curtling scream.

Franks eyes went wide, he handed Lucy to Helen, and he ran into his eldest daughter's room, only to find a man struggling with a bitting and kicking Peter.

Susan was huddled in the corner. Apparently the man had been going after her, but Peter didn't like that plan and was showing it by the bite marks on the man's arm.

"Get off me you little pirannah!" the man hissed, finally able to throw Peter against the wall.

Frank attacked the man, unwilling to let another child go. When he had the man in a place he could he growled "Where's my son?"

"Over there, bleeding." the man said pointing to a hurt Peter.

"I meant my younger one." Frank growled.

"Oh him... he's gone." the man said.

It felt like someone had just given Frank the death blow. "Gone?" he repeated.

"Yes, gone." the man replied.

The man pulled a knife and Susan screamed. "DADDY! LOOK OUT!" Peter screamed as the man turned trying to stab Frank.

He fought back though, and it was a fight to see who could get best control over the knife and drive into the other person. After a long struggle, Frank was able to get the upperhand and stab the man. The man fell to the ground and Frank backed up. He then looked over at Peter who seemed ready to faint any minute. He ran over to Peter and pulled him into his lap.

"Does anything hurt?" he asked.

"My stomach, and my head." Peter replied weakly.

Susan came over and climbed up on the bed. Frank carefully looked Peter over and had found his torso covered in bruises and a massive bump on the back of his head, but nothing life threatening. Susan left the room to go get her mother.

"I heard him." Peter said weakly.

"What?" Frank asked.

"Chris is gone." Peter said.

Frank nodded. "Why don't we keep that between us for a while." he said. Peter nodded and started drifting to sleep, but Frank shook him gently. "Peter, you can't sleep. Not right now." he said.

"Why not?" Peter asked tiredly.

"You might have a concussion. And if you go to sleep you might not wake up." Frank replied. Peter yawned and huddled close against his dad.

Helen came in. "Is he ok?" she asked.

Frank nodded. "Sleep with Susan. I've got to stay up with him." he said.

"Why?" Helen asked.

"He hit his head." he replied.

She nodded and pulled a very tired looking Susan into the room. Frank picked Peter up and carried him downstairs.

He sat down in a chair, and pulled a blanket around them both. Frank watched the clock, having to shake Peter to keep him awake every now and again. After four hours had passed, he found it safe, but instead of moving they both fell asleep as they were.
