Astrid Hofferson 

After they got back to the village Astrid headed to the lake to take a bath as she was still caved in dragon blood. She quickly stripped down and tied her clothes to a long piece of string attached to a tree. She then place her clothes in the stream so they could soak and the stream would wash the blood out. She got in and began to wash the blood off herself. Once she was clean she got dressed and walked to the mess hall still dripping wet. Once there she saw signs of a dragon in the mess hall and a large amount of food was gone. She knew it couldn't been during the fight as dozens of viking soldiers protected the grand hall. Then she remembered that no one saw the Night Furry leave and remembered that Kuro had captured it and apparently escaped afterwards but they only had Kuro's word for that and that didn't hold much weight because he was a lying little shit, She decided to head back to where she saw Kuro and as she walked out the grand hall she bumped into Raiden. 

Raiden

After the battle Raiden headed home to get the book of dragons which he kept at his house, he then took it back to the grand hall as he was about to update both his copy and the village's copy in the grand hall. He had already updated some of the information on a lot of dragons on strengths and weaknesses, he may not know them all but use the different dragon's dna to turn into a dragon hybrid enough times and you will pick a few things about them. As he made it to the grand hall he saw Astrid leaving. She clearly just taken a bath not only because she was wet but because she was no longer covered in blood and the smell of dragons. As she stopped to talk to him she told him how the Night Furry was still on Berk and why she thought so, it made sense she clearly thought it through. So he decided to follow her hunch and went with her to where they met Kuro. On the way to the forest, Ruffnut came flying through the wall of their house and landed in front of them.

The Twins 

After everyone returned to the village and the dragons had left, and the twins had finally stopped fighting, they headed home and Tuffnut began sharpening his weapon as Ruffnut laid in her bed day dreaming as usual but a few hours later they both got hungry and went down to a midnight snack. Tuffnut got to the storage room and grabbed the last chicken leg that was left over from the night before. Just as he picked it up and about to take a bite Ruffnut shot him with a lightning bolt, stunning him and knocking him to the ground. She then picked up the chicken leg which now had smoke coming off it and said,

"Thanks bro, I don't like cold chicken. How nice of you to warm it up for me."

She then continued to eat the chicken leg, Tuffnut rolled over on his back and as he tapped his foot on the ground, the ground under Ruffnut feet began to move making her wobble and her stance unstable. He then tapped his foot on the floor again and a blunt stone spike came out of the ground and smacked her in the stomach making her drop the rest of the chicken leg and spit the bit she had already eaten. He caught the chicken leg before it hit the ground with one hand and he waved his other hand towards her, shooting out five bone spikes out of his finger tips and as they stabbed her into the chest they exploded on contact sending her flying through the wall. He then got up and finished off the chicken leg as he walked outside. He saw Ruffnut laying on the ground in front of Raiden and Astrid. They both sighed and had a disappointed look on their face however they were both expected from the twins by now. The two then tried to explain the situation but the twins as usual were too busy arguing as usual to hear what they had to say and while they were choking each other they saw Raiden and Astrid heading to the woods. They were a little curious as to what as they were doing, sneaking into the woods at this kind of night thinking they were having a secret affair and didn't want anyone to know. They decided to stop fighting long enough to follow them to see what was going on. As they did they saw them standing beside a broken tree and a large pit and they saw a Terrible Terror which quickly flew away. As it did it flew past Kuro riding the Night Furry. After he landed Astrid and Raiden and the twins were about to go up to him and turn into a Night Furry. 

Astrid, Raiden and the Twins.

Astrid and Raiden looked shocked for a few reasons. They looked to each other in confusion.

Astrid. "How the hell are we going to figure out which one is which?"

Raiden thought about it for a second but before he could say anything the twins stepped in and drew their swords.

"Ah who cares who's who. Let's just kill them both and be with it. It will be more fun that way anyway."

Both Astrid and Raiden sighed as Raiden added,

"We can't kill them both, because the chief would kill us if we kill Kuro. Besides we won't need to. For two reasons. First of all we saw Kuro transform into a Night Furry. So for now we know which one is Kuro. We just have to make sure we don't mix them up and second even if we do mix them up later on, I can read their minds and figure out which one is which but even that won't be necessary for what I got planned."

He then used his psychic powers to take the harness off Night Shade. Then Astrid looked back to the others and said.

"Ok now we can kill him"

As Raiden stated,

"Hang on a minute, there are a lot of potential benefits to keeping a captured Night Furry, first of all we can learn all of it's strengths and weaknesses by studying it. Second I will finally be able to acquire Nighr Furry DNA and it would make a great final kill for the top fighter in the dragon arena. So I think we should capture it and take it back to Rogue."

Astrid agreed with and even though the twins preferred the idea of killing them both they realized they never be able to convince the others and if wasn't worth fight both fighting both Night Furries as well as Astrid and Raiden, and even if they were idiots, they knew they couldn't beat all four. The four of them drew their weapons and moved in on Night |Shade attempting to move in on him. Raiden then used the DNA of all the dragons he acquired so far. He covered his skin in gronkle scales, gave himself the ability to set himself on fire, gave himself the tail of a Deadly Natter and the roar of a Thunderdrum as well as the ability to spit fire and lava. Astrid covered her all body in ice armor. She then grew dragons wings out of back on her back made out of ice and a ice dragon tail as well. She changed her feet into and and her right hand into dragon talons and her left hand into a ice dragon head shield. She then drew a double bladed sword and got ready to fight. The twins covered themselves in bone armor and grew big bone wings out of their tail and a bone tail. They turned both their feet and their right hand into talons and her left hand into a bone dragon head shield. They all surrounded Night Shade, and now that they could all fly it was obvious Night Shade wouldn't be able to escape by flying. Astrid and Raiden were a little cautious knowing how dangerous a Night Furry could be and knowing they knew next to nothing about it. The twins however broke formation, and ran at Night Shade. Tuffnut shot exploding bone spikes out of the mouth of the dragon head shield while Ruffnut slashed at it with her sword sending out a air wave that could pretty much anything at Night Shade while they were still closing in for a follow up attack.
