Important information to know before you start reading; once a Guardian has been bitten by a Nightmare, their mind and body slowly start to become corrupted. In the end, they become puppets for Pitch Black and his army. Set shortly after the movie. Keep in mind I've only seen the movie and read other's fanfictions. I own the plotline, nothing else.
"Baby Tooth!" Jack shouted and flew after the little fairy. Just before the Nightmare swallowed her, He pulled her out of the sky. Unfortunately, he wasn't fast enough to get his hand out the way before it bit down. Jack cried out in pain. Bunny noticed and ran to help.
"What's wrong, mate? Can't handle a little Nightmare?" Bunny's teasing made Jack more reluctantly to tell him about why his hand was bleeding white ice.
"No, just one of them startled me is all." Jack knew he would probably get teased about this, but it was the first thing that came into his head. After they had finished them all off and Pitch had retreated, everyone met up at Burgess, Jack's hometown.
"That attack was pitiful at best. Why would Pitch attack such peaceful town?" North asked. Everyone else was thinking the same thing. Sandy noticed the ice wrapped around Jack's hand as a make-shift bandage, but didn't mention it. He knew Jack would tell them while they were there.
"Maybe that was a distraction. Check all your areas just in case." Tooth suggested and everyone split. Only Sandy and Jack remained.
"I'm going to go check on Jamie. Bye Sandy!" Jack tried to fly away, but Sandy grabbed his arm. An image of a hand appeared over his head,
"Oh, this? It's nothing really. I'll talk to you later." Jack pulled away before Sandy could interrogate him any further. Jack didn't want to admit it, but the bite was starting to sting. He did keep his word and went to Jamie's house. The window was open and Jamie was asleep. That concerned Jack. Why would a kid like Jamie would be sleeping on a snow day? Jack knocked before stepping in.
"Hey, kiddo. What are you doing here? Shouldn't you be out in the snow with your friends?" A snowball hit the window and Jack saw Jamie and his friends beckoning him out. He looked back at the bed and saw it empty. I must be really tired. He flew out to join in the fun; that was what he was protecting after all.
"C'mon Jack! We need another player."
*Five Days Later*
"Hey Jack, are you feeling okay?" Tooth asked. He snapped out of his daze and looked up.
"What? Oh, I'm fine. Why do you ask?" She sat down next to him on the roof and sighed.
"You've been really distant lately. Did Bunny say something? If he said something…"
"No. I just…I don't know. I think I'm starting to scare myself. Jamie himself said I was a little mopey. What do you suggest I do?" He asked. Tooth didn't really need to think.
"You could help us on the next attack. It might get your fun spirit back." Jack was about to make up another excuse when he felt something.
"Did you feel that?" He asked and stood up. Tooth hovered nearby.
"Jack, don't change the subject."
"No, seriously. I felt something. I think… I think we should check on Bunny. Follow me." Jack flew away, following the feeling in his head. Bunny's in danger. Bunny needs h-Attack! Jack lost control of the wind and fell. When he got back to his feet, he held his head. Where did that command come from? He realized his injured hand was on display when Tooth examined it. He had to keep it in ice because it still kept bleeding.
"Are you sure you're okay? And what happened to your hand?" Jack shook his head to clear it.
"I'm fine. How many times do I have to say that? We need to worry about Bunny first." He took to the skies again and traveled all the way to the South Pole. Why Bunny would be there, Jack didn't know. He could hear Tooth's teeth chattering.
"It's cold out here. Are you sure Bunny's here?"
"I'm sure. Wait here for a minute." Jack tried to get higher, but Tooth stopped him.
"Once we find him, we need to talk. Something's not right with you and we need to find out what before-"she was cut off by a grunt. Bunny was close.
"Bunny, where are you!" Jack called out. A horse whinny answered. Jack and Tooth exchanged glances. Nightmares.
"Hang on! We're coming!" Tooth flew into the direction of the whinny with Jack close behind on foot. On a mound of snow, dozens of Nightmares were pawing at the snow. Bunny was lying at the bottom, unconscious. Jack attacked the mares while Tooth tended to the rabbit.
"I'll keep them occupied, you get to the pole!" Jack commanded and tossed her one of the snow globes he "borrowed" from North. She quickly threw it and they disappeared through the swirling portal. Jack turned to face the mares, but found himself staring The Boogeyman in the eyes.
"Hello, Jack."
