Shadow blindly ran through the trees, not allowing herself to stop and rest. This was bad, she thought. Very very bad. Humans didn't cough up flames when they were sick. Hiccup would know something was wrong with her if he saw her breathing fire. She had no choice but to run. But her blurry vision was not helping her one bit.

Without warning, her head collided with a tree. The third one yet. She groaned as stood back up. Everything hurt from either colliding with a non-moving object or from the sickness that the eel was giving her. Suddenly her throat heated up until it felt like it was burning, and an explosive cough blasted from her mouth, singing the back of her throat. The bright red fire burnt a nearby tree to cinders. Hiccup would have seen that.

She took off once more. Every now and again, another cough would burst out of her mouth and singe her throat, making her breathing raw with pain. She didn't even know if her human body could withstand this much. She could permanently destroy her own vocal chords if this didn't stop.

This time, she collided with a rock.

Her head was spinning, her stomached ached, her throat was burnt raw and there was something digging into her side. Wait a minute! She looked down. Her vision was still warped and twisted, but she recognized the bag of moonstone. Suddenly, she had an idea. As she fumbled for the button on the bag, her ears were trained on her surroundings, keeping an ear out for Hiccup and Toothless.

After painfully long minutes, the top of the bag came free, and she pulled out the first moonstone she grabbed. In her sickened state, it would be dangerous to attempt this, but given the options, it was probably the best. She hopped.

Concentrating despite the pain, she willed herself to change. She could not let the dragon show itself on the outside, but on the inside…

She willed herself to change to her needs, her throat becoming fire proof and her lungs developing to hold fire. She screamed in pain as she shifted, and her vocal chords severed and redeveloped to speak in the draconic tongue.

As the shift stopped, she was able to breathe again. But the god damned sneezing and coughing didn't want to stop. Another explosive cough came out of her mouth. How many times was that? She was sure she had passed her normal shot limit.

Groaning and feeling nauseous, she kept running.

Hiccup was not having a wonderful time. In fact, today was a bit of a stressful day for him. He did not imagine that he would have to track down a sick, delusional, crazy, slightly feral girl with dragon behavior on an island with eels while seeing fireballs being blasted in the air randomly by a mysterious wild dragon, and being chased by a big green Typhoomerang.

Yea, if someone told him he'd be doing this, he would have died from laughing.

But he wasn't laughing. It's quite hard to laugh when there is a massive fire breathing dragon chasing you. Hiccup was struggling to keep in control of the situation. And frankly, he was getting more and more pissed.

"Come on bud, let's use his size against him. Up!" he said.

Toothless flapped his wings and shot into the sky, the Typhoomerang in hot pursuit. "Now, dive!" he called. Instantly, Toothless responded and twisted into a dive. The giant dragon flew after them, struggling with the tight turn due to his large size.

They turned at the last moment, just avoiding smashing on the rocks and reset their course. The Typhoomerang wasn't so lucky. He smashed head-first into the ground and laid there dazed and out for the count.

Hiccup sighed in relief. Now they just had to find Shadow and fix this mess. Easier said than done. But at least they had a lead on finding her. That wild dragon that was shooting fire balls in the air seemed to be following her, so he thought he would just follow it and it should lead to her.

He watched the island, scanning the forest for any signs of the wild dragon and its destructive tendencies.

BOOM!

There. Another explosion. Hiccup hoped that Shadow was ok. He pointed Toothless towards the explosion, telling him to be ready for anything. But there wasn't anything to be ready for. When they landed in the clearing which had been burned to ash, only Shadow was there, and no wild dragon in sight. Shadow looked horrible.

She sure felt it though.

Cautiously, Hiccup dismounted and approached her. She looked surprised to see him and opened her mouth to speak, but only growling and dragon noises came out. Hiccup and Toothless looked at her strangely.

She continued to make the noises as if she was speaking to him, but he had no idea what she was saying. Or even if what she was saying could be translated into anything legible. But when he looked at Toothless, he was shocked to see the Night Fury looking at her with interest.

Then he started making the same noises in response. Hiccup's eyes widened at the sight. Shadow and Toothless were communicating, in some sort of language that they could both speak. His jaw dropped.

Shadow sneezed.

He watched the two of them talk for a few minutes, engrossed in their communication skills. He could not believe that the two of them could speak in the dragons tongue. No, scratch that. He had no idea that there was an actual language that dragons could speak, and that Shadow, for some strange reason, could speak it.

Today was definitely a strange day. And Shadow continued to confuse him.

Toothless walked over to her and gestured to his saddlebag with his head. In response, Shadow went over to him and pulled something out. Hiccup couldn't see what it was, but he could guess its purpose.

As soon as she had eaten whatever ingredient was in the saddlebag, she doubled over in pain and started dry heaving.

He ran over to her to see if she was ok, but no sooner had he stopped in front of her, did she throw up the eel she had miraculously swallowed. To his disgust, it landed on his feet covered in saliva and stomach acid.

"Eww."

Shadow groaned and looked back up at him. She was paler than usual. Not to mentioned she looked tired and terrible. She stumbled slightly but stayed upright, clutching her bag. He watched her just stand there and get her breathing back to normal before she had the ability to speak again.

"Sorry…"

"Its ok, I guess. Are you feeling alright?" he asked. She nodded. "Better. Can we go back now, please? I want to get as far away from eels as possible." He nodded and helped her get onto the saddle. Frankly, he had enough of Eel Island too.

"If I never see another eel in my lifetime, it will be too soon."
