A/N: So when I noticed Hiccup's new leg, my first thought was that he had tweaked it so that would match his grown form. But then I thought, "What if something happened that caused him to make a whole new one?" This is my take on that thought.
It had been a perfect day for flying. After Hiccup closed the Academy for the night, he got on Toothless' back and rode off. But not before promising to be back before the sun had completely set.
Hiccup and Toothless soared over the vast waters and other islands. Occasionally they would do a death defying stunt or two. But mostly they just sailed, enjoying the setting sun.
When there was barely any sun left, they started to head back. Unfortunately things didn't go as planned.
As the pair flew over an island they hadn't charted yet, a wild Nadder flew up and fired at Toothless' tail. The Nadder was clearly not happy that they got that close.
Hiccup turned and glanced at the retreating Nadder before letting his eyes fall to his dragon's burning tail.
"Come on, Bud," Hiccup encouraged as he steered the Night Fury to the nameless island.
Unfortantely, Toothless didn't want to go near the island. It was as if he sensed how dangerous it would be for rider. Hiccup gripped the reigns harder and forced Toothless toward the island.
Taking a nosedive while only a few hundred feet above an island, clearly wasn't the smartest idea. But Hiccup didn't want to crash into the water. If that had happened, both of them would have sunk.
As Toothless hit the beach, Hiccup went flying off his back. The dragon trainer landed on his prosthetic leg, thus putting all of his weight on it. He then tumbled for several yards before landing on his back.
Hiccup slowly sat up as he rubbed his head. He look down at his legs. What he saw nearly gave him a heart attack. His prosthetic was no longer attached to the remaining part of his left leg. Instead it was laying where he had landed before tumbling. From this distance it looked to be intact.
Hiccup placed his hands on the ground in front of him and pushed himself up until he was firmly balancing on his right leg. He silently thanked the gods, that he had self-trained himself for this kind of situation.
Slowly he began to hop toward the metal leg. Halfway there, he noticed that Toothless was now standing where they had crashed just moments ago. He noticed that his dragon was looking at him with bemused expression plastering his scaly faced.
"You think this funny, don't ya?" Hiccup asked as he took a couple more hops.
Toothless nodded as he let out a playful growl.
"You know, I don't have to fix that tail of yours. I could easily get another dragon to take us home," Hiccup replied.
The Night Fury's smiled melted and began to walk toward his rider.
"That's what I thought," Hiccup said as he reached his destination. He looked down the false leg and noticed that the metal was bent and that the wood was broken into pieces.
Hiccup slowly began to lower himself, until he was sitting firmly on the ground. He picked up the now ruined metal and just stared at.
"After all these years. Years full of crash landings, stunts, and stupid things, it breaks," Hiccup muttered as Toothless nudged him. "It breaks now."
Toothless growled softly, as if understanding and feeling his human's emotional pain. That leg was the only thing that could get them home.
Hiccup threw the messed up metal as far he could. The Night Fury went after it, making sure that it didn't land in the water.
"Don't bother Toothless. I have no way to fix it. It's useless," Hiccup called out as he scooted over a nearby rock and leaned against it. "I'll make a new one when we get back to Berk."
'If we get back,' Hiccup thought. He didn't want to voice his worry to his Night Fury.
Toothless bounded over to him and placed the broken metal in front of his foot.
"It's broken, Bud. Besides if I wanted to fix it, I couldn't," Hiccup stated. "It's dark. Try and get some rest. We'll go looking for a dragon that can take us both home tomorrow."
Toothless fired a plasma blasted into the sand, thus making a small, but long burning fire. He then laid down close to his dozing human. He wasn't going to sleep though. This island was different from the other islands. He was going to keep watch and protect Hiccup.
