A/N: So, first ending. This is the only thing I own of this entire story.

DISCLAIMER: I still don't believe I have to do this EVERY CHAPTER. If I did own the characters, why would I be writing fanfiction of them? HMM?

Ending 1

Hiccup crashed through the window, the ice shards sprinkled on the floor around him. He looked around the room and saw Jack looking up at him, his icy blue eyes full of fear and panic. He started walking over to him, his metal leg slipping on the icy floor.

'Why did I have to fight a winter spirit?' He thought bitterly. Jack started running away, his staff trailing on the ground behind him. Hiccup tried to follow behind, but he kept falling or slipping. Hiccup just tried to follow the trail of frost that formed on the ice, but sometimes it would twist on the wall, or the ceiling.

Hiccup kept running through the castle. He neared a room and found Jack bent over by a wall, trying to catch his breath.

Hiccup ran after Jack, a little slower because he was having trouble keeping his balance on the ice. "Oh, hello, Frost." Hiccup said, coming to a stop a few yards from the immortal. Jack's head snapped up, his eyes wide like an animal's. The spirit frantically looked for a way out, only finding one. The one behind the one-legged fool.

Hiccup quickly unsheathed his sword, extending the blade and lighting it on fire. He took a few steps towards Jack, which made Jack raise his staff defensively. "Good job, Jack, a flaming sword against a stick. I'm so scared." Hiccup teased, but inside he knew how dangerous the winter spirit could become, even with them being in an ice castle of all things.

The young adult ran at the old teen, swinging the sword like a mad man, melting the thin floor beneath them. Jack's eyes glanced at the thinning floor, then at the person in front of him. "HICCUP!" Jack bellowed. "IF YOU CONTINUE THIS, ELSA WILL DIE!"

The man faltered for a second. "Is that just another way to make me reconsider my actions?" Hiccup sneered. "If that is the case, it's a pathetic try." Hiccup advanced faster, getting better at controlling his mad rage to kill the other and making Jack move against the wall.

Hiccup saw the act of weakness, and brought his sword down at Jack. The sword got lodged in the ice wall. Jack made a nervously look at the flaming sword inches from his head, burning some of his hair on the top of his head. Hiccup jerked his sword, trying to get it out, it didn't budge.

Jack saw the sliver of fear in the green eyes. The young spirit ran away from where Hiccup kept trying to unlatch his sword. Jack, spinning his staff in one hand, brought it down and caused ice crystals to form in the weakened ice. The frost crawled towards Hiccup, growing in width.

Hiccup, finally getting his sword out if the wall, noticed the ice for the first time. "Going to scare me with this ice? Funny." The frost slowly climbed out of the floor, forming walls of ice. Jack slowly released the breath that was caught in his throat.

He quietly began to walk out of the room, a free - but shaken - boy. His grin that normally graced his face came back. His bare feet just left the doorway when a cracking noise came behind him.

The ice walls were beginning to come apart, same fractures at first, and then grew the arm length cracks. A wavering glow of flame came from within. 'He's trying to break out.' Jack thought. 'I need to get out of here, quickly .'

Jack bounded out of the hallway, the sound of the ice breaking echoing off the walls. As Jack got halfway down the stairs, the sound of crashing ice rumbled through the castle, magnified by the walls. Jack made the quick decision to stand and fight. He ran back upstairs, staff sliding behind him.

The scene Jack found was unlike anything he ever seen from the young Viking. The auburn haired man lay around the destroyed ice walls; his sword lay abandoned across the room. The young man looked defeated; his face was bloodied like he used it to break the ice.

Jack already had a hundred of remarks to tell Hiccup. He shoved them to the back of his head, and then walked over to help his ex-best friend, his own reason unknown to him. He brought Hiccup's arm around his neck and picked him up. "Hiccup, what am I going to do with you?"

A strangled gurgle came from the brunette's throat. "I know, I know. You attacked me and you think I would hurt you. But, I'm not that kind of person." Jack stated. "We just need to bring you to Arendelle, we'll get some doctors to look at you." A cough came from the person stationed on Jack's back; something warm went on Jack's neck, then oozing down his back. The spirit shook Hiccup, trying to keep him conscious. "Come on, Hiccup, is this really the Viking in you?" Jack said, getting to the stairs of the castle.

Jack took the steps one at a time, trying not to slip with Hiccup on his back. "Let go of me." Hiccup whispered, though more of a grumble. Jack only held tighter as Hiccup started shaking around.

"Didn't you hear me?" Hiccup said, getting only a bit louder. "I said, 'let go of me!'" Hiccup did one final push off of Jack, causing Jack to lose his grip. Hiccup slammed into the ice, fracturing it. The white haired teen danced down the rest of the staircase, going down three at a time.

Hiccup brought his head up from his miserable heap. He saw the teen at the bottom of the stairs. Hiccup slowly picked himself up, relying heavily on the rail. He slowly came down, clutching his side as the red liquid dripped down. 'Hiccup Horrendous Haddock III, slayer of Jack Frost.' Hiccup thought to himself. 'Yeah right. I'm going to die here.'

Hiccup looked back at the spirit, and then he slumped back down, falling down the stairs. Jack ran up the stairs to try and catch the falling Viking. Jack looked at the clouding up eyes of the young man.

"Good...bye, ...Jack." Hiccup gasped out.

"Goodbye, Hiccup." Jack said as the remaining breath left Hiccup's lungs. "And may you go to Valhalla, and join Odin." He finished, closing Hiccup's eyes. Jack slowly stood up, tears running down his pale cheeks. "Let's bring you home and give you a proper burial." He picked him up for the last time and flew off, flying northward to Berk.

A/N: I don't think many of you know this, but Jack Frost came from the Nordic legend Jokul Frosti. Fun fact for the day, brought to you by happybear135. And only People who died in battle get to be accepted into the halls of Valhalla, and when the days of RagnarÓ§k, they will begin the fighting. So, I did do some research for this story, better than some of my school papers.
