I Do Not Own How To Train Your Dragon
Failure
There were so many things Hiccup couldn't do. He couldn't help build new ships for the tribe, which was nearly mandatory. He couldn't go hunting, because he didn't have the heart to kill. Hell, he couldn't even hold Astrid's affection for long. Within a month after Snoggletog, she was off and in love with someone who's name he didn' even know.
"I'm a failure, Toothless." Hiccup told his best friend one night, when they were just sitting in Hiccup's room. The dragon perked head head up, cocking it to one side. "I can't do anything right."
As is sensing his best friend's anguish, Toothless got up off the floor. He nuzzled his flat nose against Hiccup's hand, and made snorting noises.
"You wouldn't understand..." Hiccup scratched Toothless's head.
Toothless's eyes lit up in an idea. He bit at Hiccup's sleeve, pulling him off the bed. Despite Hiccup's protesting, Toothless continued to pull, then started pawing at the door. Finally, Hiccup realized what Toothless wanted.
"You want to go for a ride?" Hiccup asked. He reached for the saddle. When Toothless growled a bit, Hiccup grabbed his re-make of the tail he had made for Toothless for Snoggletog. "You want to choose?" Toothless gave him a gummy grin. "Okay, I guess so."
With that, Hiccup climbed onto Toothless's back, and they were off. Hiccup had no idea where they were going. He knew only that they were going, and that as soon as they hit the air, he felt free. The weight that pushed down on his shoulders disappeared, though only by a bit.
Toothless began to descend sooner than Hiccup had expected. Within seconds, Toothless had landed in a familiar, hidden cove. It was the place where their friendship had begun.
"Why'd you bring us here?"Hiccup got off of Toothless. Nothing had changed since that day, so many years ago.
Toothless began flying around, acting as if he wasn't wearing his prosthetic tail. He attempted to climb one of the cliffs, only to fall back dramatically. He continued on with his act for a few minutes before Hiccup got what he meant.
"Okay, so I saved you. That's the only good I've done."
Toothless shook his head. He imitated the Green Death, then showed the huge dragon being shot down. With a shutter, Toothless played dead. He sprung to life though, waiting to see his friend's reaction.
"And we killed the Green Death. But you were the real hero."
This wasn't good enough for Toothless. He needed to see Hiccup with a huge grin of his face, and he needed to see Hiccup happy with himself. Out of the corner of his eye, Toothless saw a rock. He stood up, and lunged at it in a mock attack. Then, he cuddled up to it as if it was Hiccup.
Toothless bound over to Hiccup, mauling him with 'dragon love'.
Maybe Toothless is right, Hiccup thought latter that night when they were flying home under the light of the full moon. Maybe I'm not a failure. At that realization, Hiccup smiled and wrapped his arms around Toothless's neck.
"Thanks boy, I needed that."
I hope this is what you wanted!
