So, I don't know if this idea has already been tackled [I have yet to read (or notice) all the stories in this category, lol], but if that's the case, I did not steal it from anyone. I came up with this today while listening to the HTTYD soundtrack on my computer. I think inspiration struck when listening to the track, "Where's Hiccup?" It's not very good; the story, I mean. But, I gave it my best shot! Anyways, enjoy.

I do not own How to Train Your Dragon or any of its characters. :[

He hadn't noticed it at first. It was such a little thing that nobody else would even waste time fussing over it. But Toothless was his best friend [and was also quite curious], so he was determined to find out what it was that Hiccup was hiding.

One day, after an exciting flight through the sky, Hiccup and Toothless landed back on the ground. A patch of dirt, right beside a small lake. The place where they had both "officially" met. After an eventful day, they always came down there to relax.

Hiccup hopped off Toothless' back and sat in the grass, cross-legged. The Night Fury leaned over the lake to drink. His tongue quietly lapped at the water, keeping the field at a peaceful silence. It was then Toothless noticed Hiccup slightly turn his head. Afraid he might miss something, Toothless slowed his strokes and watched the boy carefully.

Hiccup's eyes trailed down the dragon's scaled body. His gaze stopped when it reached the end. Toothless cocked his head. He was looking at his flying contraption? No, his tail. His wounded tail. Hiccup's eyes laid there for a moment or so, just staring. An upsetting sigh escaped from the boy's mouth. The noise itself was enough to make Toothless cry. If dragons could cry, that is.

Suddenly, Hiccup blinked and turned to face his dragon. Toothless whisked his head around, acting as if he saw nothing. Through his side vision, he saw the boy rub his eyes with the palm of his hand and stand up.

"Well, we'd better get going, buddy," Hiccup stated, patting at the dragon's neck. Toothless faced him. There was a smile on the boy's face, but Toothless could easy see past it.

It was obvious, of course, even to a dragon, what Hiccup had been feeling just then, while looking at Toothless' tail wing. Sorrow, remorse, anguish...guilt. Toothless never blamed Hiccup for what had happened, of course, but that didn't stop Hiccup from regretting what had happened in the first place.

Hiccup saddled up on his dragon's back, getting ready to take off. Toothless looked up at his best friend. The smile Hiccup now wore was sincere. The grief of the previous moment had washed away, hiding beneath the surface.

Toothless lowered his eyes, focusing on something else entirely. He stood there for a moment, thinking.

"Ready to go?" Hiccup asked, slightly concerned that the dragon hadn't yet taken off.

Toothless shook away his recent thoughts and nodded. Then, they flew off into the skies, both hiding a similar secret. Because what Hiccup didn't realize was, every so often, when Toothless caught sight of the boy's injured leg, he too felt guilt.

Wow, it's short, lol. Thanks for reading. Comments are love. :]
