Chapter 7: The Tail-fin

"...And with one twist, he took my hand, and swallowed it whole. The look on his face was as clear as day, I was delicious. He must have told the other dragons, because it wasn't a month before another one of bit my leg clean off."

Later on, the twins went back to Berk to join Gobber and the other teens for dinner at the watch tower as Gobber shared the tale of how he lost his limbs. Hicca and Astrid refused to acknowledge each others' presence after the Nadder incident and when they did make eye contact, they both glared daggers at each other.

"Isn't it weird to think that your hand was travelling down a dragons' stomach? Like if you could still control it then you could have killed the dragon from the inside by crushing his heart, or breaking its bones or something." Fishlegs said, earning weird looks from the others.

This caused Hicca to roll her eyes "That is completely flawed. When a persons' arm gets cut off, so does the nerves that connects the arm to the brain. Since the brain has no way to send nerve impulses to the arm, it can no longer be in control of it at all. What Fishlegs is saying completely defies that." She whispered to her brother who nodded in understanding. He doesn't have the level of knowledge that his sister has in medicine, but he knew enough to be able to keep up with her.

"I swear, I'm so angry right now! I'll revenge for your beautiful hand and your beautiful foot. I'll run up to the dragons and chop off every limb in their body. With my face!" Snotlout boasted.

"At least he'll use his head for something." Hiccup whispered to his sister causing her to giggle.

"Un-unh. Don't aim for its limbs, aim for its wings and tails. If it can't fly, then it can't escape. A downed dragon is a dead dragon." Gobber informed them.

This made the Haddock twins look up, horrified. One look exchanged and they knew exactly what the other was thinking.

Oblivious to the Haddock twins' reaction, Gobber then got up "Alright. I'm off to bed. You should be, too. Tomorrow we get to the big leagues. We will be slowly climbing up towards the Monstrous Nightmare. But who'll win the honour of killing it? "

"Definitely me. It is my destiny after all. See?" Tuffnut bragged showing everyone his mark.

Fishlegs gasped "Your Mom let you get a tattoo? How?"

"It's not a tattoo, idiot. It's a birthmark. It's been with me since birth"

"Okay, I've been stuck with you since birth, and I have never seen that before." Ruffnut said.

"That's because you've just never seen me from the left side until now."

Astrid then turned and noticed that two people were missing. Walking towards the spiral stairs, she saw Hiccup and Hicca leaving in a hurry. She then dismissed it and went back to where the others were. What those two were up to was not something she would care about, especially not after today.

Hiccup and Hicca made their way to the forge, their goal clear in their minds.

"A downed dragon is a dead dragon." Hicca stated.

"Not if we do something about it." Hiccup said with a determined look.

The two then worked rigorously, finding every scrap of metal and leather they could find. After they were done, Hiccup held up the finished product, a prosthetic tailfin.

"You think this will work?" He asked his sister.

"Only one way to find out." She replied. Then a thought entered her mind "Hey bro, I was thinking. Why don't we name the two Night Furies? Just to avoid confusion. If you don't mind I would like to name the female Night Fury."

"That's exactly what I was thinking of. I even have a name picked for the male Night Fury."

"I also have one picked for the female."

They then spoke at the same time "Toothless. Wait, what?"

"We can't name them both Toothless." Hicca said with her arms crossed.

"You're right. There's only one thing to do." Hiccup said as he went and picked up at dagger "Call it." He said as he tossed the dagger in the air.

"Black." Hicca said just before the dagger landed. They both took a closer look at the dagger and saw...

"Ha! Grey side! Pick a new name." A year ago the Haddock twins heard a story from Gobber about how the Hysterics' chief, Norbert the Nutjob, decided his prisoners' fate by tossing his axe. From that story, the twins got the idea to get a dagger and paint one side black and the other side grey and use it to help them with some of their decisions.

Hicca huffed at losing the right to the name then tried to come up with a new one "Let's see. New name, new name, new name..." She then saw the Night Fury scales she collected the other day on her table and got an idea. "Midnight. I will name the female Night Fury Midnight." She declared.
