A/N: Here's a code I made up for you so this is easier to read.

Bold: Dragons are talking
Italics: Humans are thinking
Bold italics: Dragons are thinking
Underlined: Any language being spoken that isn't either Norse or Dragonese by bilingual/multilingual characters. It will be written like this for humans:

*Language goes here "Insert speech here."

And like this for dragons:

*Language goes here "Insert speech here."

If there isn't a language in front of the speech, assume that they are speaking Norse if they're human and Dragonese if they're dragons. Sorry about giving such a long A/N, but I felt I had to explain this for you.

Today was not going to be a good one for Starlight and Toothless, although they didn't know it yet. It started out fine with their usual daily routine of messing with the two nerds in their lives. Brenna got her leg taken from her as she slept and Toothless dragged Hiccup out of bed and literally carried him downstairs (at the orders of his father, who was very pleased with the result).

"How are you this much of a jerk?" Brenna asked in exasperation, as her dragon casually toyed with her prosthetic.

*Norse "I hatched like that," Starlight explained. *Norse "How are you not fighting back?"

"Oh, you want me to fight back?" Brenna asked, grinning sadistically. "Fine." She whistled, and the prosthetic flew to her hand. Starlight grumbled as Brenna attached the prosthetic.

*Norse "And you say I'm a jerk," Starlight sighed. *Norse "Go get me breakfast, dork."

"I left it in the kitchen," Brenna replied. Starlight went to get it, only to find that Brenna had boobytrapped the kitchen. She was hauled into the air by a net.

*Norse "BRENNA!" Starlight screamed. Brenna went into the kitchen, looked at the trussed up dragon, and laughed hysterically.

"This is priceless!" Brenna laughed. Starlight rolled her eyes.

"Shut up and get me down from here!" Starlight ordered, no longer bothering to speak Norse. Brenna was still laughing as she undid the series of pulleys that hoisted Starlight above ground, lowering her down safely. "I hate you."

"Noted. So . . . are you going to kill me before or after breakfast?" Brenna asked, grinning.

"After breakfast, because I'm hungry," Starlight huffed. As she ate, Brenna grabbed an apple, got changed into a typical outfit of blue dress, grey fleece for warmth and black trousers and teleported herself out with the snap of her fingers. She met Hiccup and Astrid on the way to the Great Hall.

"Hey," she greeted. Hiccup and Astrid sought help from her immediately. They both looked very frantic.

"We need you to hide us!" he pleaded. "We have an angry Night Fury after us! Is there any way you could hide us?"

"Hold on a second. Hiccup, isn't Toothless your dragon? And why is Astrid in danger?"

"Toothless fell asleep after messing with us and we got some paint and paint brushes and then we drew on his face and wings," Hiccup blurted out. Brenna snorted.

"That's one I have to remember," Brenna grinned. "I have no idea why you want me to hide you from the big bad Night Fury by placing you in close proximity to another Night Fury."

"Fair point," Hiccup admitted. "Maybe your magic can help us get away from them." Astrid smiled. This should be good.

"Then come with me so we can get some privacy. I don't like to do magic in public unless I have to. It freaks people out," Brenna explained, dragging them behind her house. Then she created a blue sparks between her hands, which swirled in thin air until it flattened out and turned itself into a round, perfect circle. Brenna muttered some spell under her breath, and soon Hiccup and Astrid could see an island with no dragons on it. Brenna widened the portal by whistling, and then she motioned for her friends to just walk through. This was a portal they were seeing. "Come on." That was the last thing she said before she walked right through the portal as if it was any normal door, leaving them on the other side on their own.

"Should we go with her?" Hiccup asked.

"It's either Brenna or Toothless," Astrid told him, before stepping through. Hiccup didn't want to be left alone and stepped through, finding himself in a whole new world. The couple realized that they were on the island where they first encountered Brenna and Starlight, and nothing seemed to have changed. It was still a lush paradise, perfect for dragons. It was just really weird that none of them lived there. It had fish, water and shelter for them and their mates and hatchlings up in the caves.

"Why'd you take us here?" Hiccup asked.

"Because even if they do realize we're here, by the time Starlight flies out here to get to us, it'll be too late," Brenna replied. "You said you needed a hiding place, right? This is pretty far away from Berk. I heard Stormfly talking about needing two rest breaks because the journey took so long."

"Why did you only say Starlight?" Hiccup asked.

"Wait, can Toothless' tailfin let him fly without you?" Brenna asked, momentarily confused.

"No," Hiccup replied.

"Then I was right the first time," Brenna replied, not confused any more and returning to the confident, knowledgeable manner she'd adopted. "Until Starlight gets here and drags us back to her boyfriend for us all to die, might as well get something to eat. Who's hungry? Some of the fish traps I left out here should still be working. We'll set up a fire and cook it out in the open while awaiting Night Fury-related doom."

"Why does this sound like a really good idea?" Astrid asked.

"No idea, but I'm in," Hiccup agreed.

"Fine. You two, come with me," Brenna ordered, and off they went to get some proper food and await their inevitable deaths. Typical things that friends did together.

Meanwhile, on Berk, Toothless had cleaned off all the paint Hiccup and Astrid had left on his scales and was now looking for Starlight. "Starlight, have you seen Hiccup and/or Astrid anywhere?" he asked.

"No; why?" the female Night Fury queried.

"They put paint all over me when I was asleep and now I want revenge," Toothless told her. Starlight raised an eye-ridge at the odd behaviour. That wasn't like the nerds they knew. They usually did nerdy stuff all day and only planned pranks after being provoked.

"Since we're talking about nerds, have you seen Brenna anywhere?" Starlight asked.

"No; why?" Toothless asked.

"She set up a trap in the kitchen when I was getting breakfast," Starlight told him.

"Maybe they all left together," Toothless suggested. "Stormfly should be gone, too."

"Let's check," Starlight suggested. They went over to the stables and found Stormfly chatting with Meatlug. Since they weren't expecting it, they stared in shock.

"Are you two OK?" Stormfly asked.

"Have you seen Astrid anywhere?" Starlight blurted out.

"Not for a while, why?" Stormfly answered.

"We've just been wondering where she is. Our riders are gone, too, and since Hiccup and Brenna are gone, too, we were wondering if it was related," Starlight explained.

"That makes a lot more sense now," Meatlug said. "For a moment, I thought you'd gone crazy."

"Yeah, me too," Stormfly agreed. Toothless and Starlight rolled their eyes.

"Oh, thanks for the vote of confidence," Starlight huffed, before they both left.

"I'm beginning to worry about those two," Stormfly muttered, once they were gone and well out of earshot.

"Same here," Meatlug agreed.

Meanwhile, back at the unnamed island, Hiccup, Astrid and Brenna were eating cooked fish and passing around berries that had somehow been growing in her absence. In general, they were having a much better time than their dragons, who were freaking out because they couldn't find their riders anywhere. (Toothless and Starlight were freaking out; Stormfly was fine.)

"You make some really nice fish, Brenna," Astrid commented, as she ate.

Brenna blushed. "Thank you. I'm just glad that I forgot to take down those fish traps I set up when I got here."

"So getting food is more convenient?" Hiccup suggested.

"No, Hiccup, so I can see if the massive plant with teeth prefers salmon or haddock for its breakfast," Brenna sassed. Astrid giggled, and Hiccup huffed, pouting. The girls grinned at each other. "Does he always pout like that?"

"Only when he's annoyed," Astrid explained.

"I am right here, you know, " Hiccup huffed, rolling his eyes.

"He is definitely pouting now," Brenna snickered.

"Am not," he retorted.

"Are too," Astrid butted in.

"Am not!"

"Are too!"

"Am not!"

"I'll see if I left anything behind," Brenna muttered, slipping away into her old house. She thought that maybe she'd left behind some journals made on her travels, and the magic-using redhead was right. Three big books of journal entries were stacked up on top of each other. Brenna picked one up to flip through, and out of its pages burst an explosion of colour and noise. Quickly, Brenna closed the book, hoping that Hiccup and Astrid didn't hear anything. Luckily for her, they were busy arguing. There was no room for her in their . . . discussion.

"Astrid, I am not stubborn!" Hiccup retorted.

"Listen to yourself!" Astrid snapped. Brenna stuck her head out of the door. She had to stop this somehow.

"Did you say anything?" she asked. "I could have sworn someone said my name." It was a blatant lie, but she'd always hated the sound of arguing.

"No," they chorused.

"Oh." Brenna took this moment to sit down. "Anyway, now I have your undivided attention, would you like to go home now? I'm sure our dragons are worried about us."

"Well, how would you know? We can't see them, can we?" Hiccup snapped. He didn't mean to be so short with her, but he'd just been in an argument with his girlfriend and his ego felt a little fragile.

"The magic I used to get you here is the same type I need to see what's happening on Berk," Brenna pointed out. "And our dragons are . . . freaking out."

"Do you know that because you can use your magic to see what they're doing right now?" Hiccup asked.

"No, Hiccup. I know that because if they were gone with no sign of which direction they had gone in and we were on Berk, we'd be going crazy," Brenna replied. "Toothless and Starlight learned a lot from us, you know."

"Fair point," Hiccup admitted. "Let's go home." Brenna, once again, created a ball of blue sparks in her hands and widened it with a long, low whistle until it was big enough for them to step through. Then she took her old diaries with her when they weren't looking. They, with less fear this time, stepped through it, finding themselves behind Brenna's house, meaning everything came back full circle. They emerged from behind Brenna's house, only to be tackled to the floor and licked by two very anxious Night Furies.

*Norse "Where were you? Why didn't you tell us? What took you so long?" Starlight babbled.

"Don't ever disappear like that again, Hiccup, please," Toothless pleaded.

"Easy, easy! We just went to the island where a lot of our stuff is to retrieve some of it to put in our house and use some of the fish traps to get a proper breakfast," Brenna explained.

*Norse "What sort of stuff?" Starlight asked.

"Just these old sketchbooks, nothing you'd be interested in," the redheaded female remarked.

*Norse "But I thought those were your diaries, Brenna," Starlight said. *Norse "Those books that you're holding right now." Everyone stared at Brenna.

"You kept a diary?" Hiccup asked. "What did you write in it?"

"That's for me to know, and for you to stay up pouting about because I'm not telling you," Brenna sassed. "I didn't even want to tell anyone that I had a diary in the first place, but that plan was foiled by the walking reason to never teach any dragon how to speak Norse ever."

*Norse "Hey!" Starlight snapped. Toothless fought back laughter. It was a mean joke directed at his girlfriend, but it was funny. Starlight tail-slapped him.

"Ow!" Toothless yelped.

"You earned that one," Starlight huffed.

"Why did you keep a diary?" Astrid asked.

"The things I saw were insane, and sometimes I thought I was having a weird dream and I would wake up soon. Having a diary helped me come to terms with the fact that it was real," Brenna explained.

*Norse "Also, she wanted somewhere to put all her sappy thoughts of homesickness," Starlight interrupted. Brenna glared at her, and then created blue sparks between her hands. Blue became light grey, and then the grey ball grew in size (roughly the same size of a barrel of ale) and began to hover over Starlight's head. *Norse "Oh, great, more magic. What does this spell do?" Starlight asked, rolling her eyes.

"It's just a storm cloud, Starlight," Brenna informed.

"Storm cloud?" Toothless chimed in.

"Yes, Toothless, a storm cloud. Like the ones in the sky. Watch this," Brenna asserted. A rumble of thunder could be heard from the storm cloud.

*Norse "Sounds like your stomach," Starlight joked. A bolt of lightning struck the floor in front of them, leaving behind a scorch mark. Both Night Furies jumped.

"AAAAAARGH!" they screamed. Both nerds stifled laughter.

"First you leave a net trap in the house, then this!" Starlight snapped. "I may be the unholy offspring of lightning and death itself, Brenna Bloodsword, but you're going to be the death of me!"

"Wait; your humans pranked you, too?" Toothless blurted out, incredulous. "I thought the only humans that did that were Hiccup and Astrid."

"No, my human's an utter jerk, too," Starlight reassured. "She hid a net inside the kitchen and sent me downstairs to get my food! I have no idea how long she'd been planning this, but if it was supposed to make me angry, it worked!"

"And Hiccup and Astrid drew on my face with paint!" Toothless complained. They glared at the nervously chuckling nerds and came to a silent conclusion: revenge was in order.

"You thinking what I'm thinking?" Hiccup asked.

"That we shouldn't be near any angry Night Furies?" Brenna asked.

"Exactly," Hiccup agreed, and they ran like Hel. Toothless and Starlight chased after them, but Toothless wouldn't start the chase before licking Astrid's face and getting drool all over her clothes. (After all, she had helped.) People glanced at the spectacle, chuckled, and got on with other stuff they had to do.

"What's happening now?" Gobber asked.

"Hiccup must have been messing with Toothless, and now Toothless is chasing him," Stoick explained. "It's pretty common. Toothless will probably tackle Hiccup to the ground or throw him somewhere in about 3, 2, 1 . . ." A loud splash should be heard, far too loud for it to be human and definitely too loud for it to be Hiccup. Hiccup had tricked Toothless into running really fast and then getting out of the way just in time.

"HEY!" Toothless yelled, as he was thrown into the sea. Stoick raised a single eyebrow out of curiosity. This was not normally what happened.

"Oh, look, it's that Brenna girl who just came to the island," Gobber pointed out, as Brenna ran for her life from Starlight. "Reckon the same thing will happen to her dragon?"

"Nah. They may both be Night Furies, but they can't be that much alike," Stoick discounted. A loud splash could be heard just after that sentence had been finished.

"HEY!" Starlight yelled, as she lost her balance into the sea.

"I stand corrected," Stoick muttered, as Gobber lost his mind laughing. Toothless and Starlight eventually emerged from the sea with pissed off looks on their faces, to the laughter and cheering of the other Berkians and dragons.

"We're not living this one down, are we?" Starlight asked.

"Nope," Toothless told her. Brenna was whistling innocently as she checked on her prosthetic leg.

"Oh, hello," she greeted, taking the false leg apart and reconstructing it to see if it worked properly.

"Jerk," Starlight growled.

"Wait, so you can wake me up by tipping the bed over while I am still in it, eat my food at breakfast and tell other people about the dumb stuff we used to do together as kids, but I plan one prank and I'm a jerk?" Brenna asked. Starlight growled and settled for tail-slapping her rider around the head. "WHOA!" Brenna yelped, ducking out of the way just in time to avoid a Night Fury's tailfin to the face.

"Serves you right," she huffed, looking down her snout at the giggling nerds. "Honestly, what would you say right now if Toothless and I decided to sit on you both?"

"I feed this Night Fury too much," they chorused, before staring at the other one with shock that they said the same thing as them.

"As I suspected. Nerdy minds think alike," Starlight sarcastically remarked to Toothless, over the laughter of other Vikings and dragons. The laughter only increased after seeing the looks of utter shock on Hiccup and Brenna's faces as they stared at each other.

"How the Hel did you know what I was going to say?" they asked each other, again speaking in unison. Now there was another funny thing for them to laugh at: how Hiccup and Brenna said the same thing at the same time. "Are you reading my mind or something?"

"Now this is funny!" Toothless giggled.

"Totally worth being dunked into the sea," Starlight summarized.

"Why are you saying the same stuff as me? Are you enchanted or something?" The nerds quizzed each other on how they were predicting each other's speech, while their Night Furies laughed. "Will you two shut up?" they yelled to their Night Furies, which only made everyone laugh even more.

"This is funny and all, but all good things come to an end eventually, and I think I know how," Astrid grinned.

"You can, huh? Prove it!" Snotlout dared. Astrid grinned, and stepped forwards. Soon, a shrill whistle cut through the air that made everyone stop and stare.

"Hiccup! Brenna! Which one of you is the most experienced with dragons?" the blonde asked.

"Him," Brenna said, pointing at Hiccup.

"Her," Hiccup said, pointing at Brenna. Everything came to a standstill.

"Wait; what did I just witness?" Astrid asked herself aloud.

"Now this can't be right. I can't be the one who knows more about dragons. You got to live with a Night Fury all your life. You taught Starlight how to speak Norse, and she taught you Dragonese. You translate for dragons at the blink of an eye like it's nothing. Before, people would kill dragons as revenge for destroying our homes and also for sport. But you've been living alongside one all your life. How am I the one with more experience?" Hiccup asked.

"Now this can't be right. You've basically rewritten the entire book on dragons, got to study them, interact with them. The people in my village thought dragons were extinct. Nobody knew Starlight was a Night Fury until a traveller saw her, told some official something about Starlight being lightning and death and ran away to his boat, screaming like crazy. How am I the one with more experience?" Brenna asked.

"Your village thought dragons were extinct?" Hiccup repeated. A few Vikings snickered.

"I know. It may sound crazy to you, Hiccup, because you grew up with dragons, but not all villages have their own Book of Dragons to consult," Brenna pointed out. "Until she was twelve, Starlight was registered as an exotic winged lizard, from place unknown. They had no idea she was a dragon."

"Exotic winged lizard?" Toothless repeated, horribly confused. "Seriously?"

"Not a word if you know what's good for you," Starlight groaned, placing her paws over her eyes.

"Wait a minute . . . if Starlight knew Dragonese without meeting another dragon while growing up . . . then dragons must have an ability to speak Dragonese embedded into them from the point of hatching! Language is an innate ability for dragons! It's behaviours like hunting, flying and draconic social skills that are taught by the parents! That is so cool!" the resident nerds chorused, celebrating. Their Night Furies rolled their eyes.

"So dorky," Starlight muttered.

"At least if they're too busy celebrating, then they can't go anywhere," Toothless said, trying to be the optimist.

"Quickly! We have no time to waste! Where's the Book of Dragons?" Brenna asked.

"I left it in the Great Hall. Come on, we have to go!" Hiccup told her, and they ran off.

"Oh look, you spoke too soon," Starlight noted. "Well, I guess we have to go, now."

"What for?" Toothless asked.

"Our nerds can't be left alone," the female Night Fury explained to her male counterpart. "Come on, I'll race you."

"Can't say no to that!" Toothless agreed. They raced each other to the Great Hall, where they witnessed their riders editing the Book of Dragons. Toothless, being the only dragon that could read, looked over their shoulders and gasped with shock. "Hey! You two have got a lot of nerve!"

"What now?" Starlight asked. "What does it say?"

"Night Furies: the unapologetic jerks of the dragon world," Toothless read.

"Why, those smug little nerds!" Starlight snapped. "Just wait till I get my claws on them!"

"Starlight, they're still there," Toothless pointed out. Hiccup and Brenna waved at the enraged Night Furies. Then they ran, and the Night Furies chased them.

"Get them!" Starlight ordered.

"Now would be a good time for another portal-thingy, Brenna," Hiccup panted.

"I know. We just need to lose them first," Brenna gasped.

*Norse "We heard that, you know!" Starlight yelled. Hiccup and Brenna ran faster, took turn after turn to shake them off . . . until, finally, they did it. They lost them. They found themselves in a disused, dusty backstreet nicknamed "Drunkards' Alley", aptly named for the astonishing rate of drunk people falling asleep there after what had to have been a very good night.

"They're gone, right?" Hiccup gasped, trying to catch his breath.

"Right," Brenna confirmed, leaning against the wall.

*Norse "Wrong!" Starlight denied, as she and Toothless swung down from the rooftops of the two houses, grabbed their riders and took them to the cove. Hiccup and Brenna screamed, cursed (well, Brenna cursed, but Hiccup didn't) and fought, but it was useless.

*Dragonese "Hey, Starlight, put me down!" Brenna demanded.

"Get off of me!" Hiccup snapped. "Where are we going?"

*Norse "You'll find out once we get there," Starlight grinned.

"Oh, stop being so overdramatic," the nerds chorused, rolling their eyes at their dorky Night Furies. The Night Furies in question gasped at the absolute cheek of it all.

"They so deserve what's coming to them," Toothless huffed.

"I completely agree," Starlight grinned. "Where and who do we start with first?"

"Both of them at the same time," Toothless replied.

"Yeah, good call," Starlight agreed.

"What are they saying?" Hiccup asked.

"They're picking who to start with. I don't know what they're thinking, though," Brenna replied. "That would require magic, and they're immune."

"Oh, right. Dammit," Hiccup sighed. Starlight decided to shut this translation scheme down so Hiccup didn't know anything else about their plan.

"That's enough out of you," Starlight grinned, placing a paw over Brenna's mouth so the only thing Hiccup could hear was faint angry mumbles. This wasn't going to end well for either of them. Both nerds saw Night Fury tongues sticking out, put two and two together, and almost screamed. But then it was too late.

"Eww! Off, off, off!" Hiccup commanded, as his brown hair stuck straight up with Night Fury saliva.

"Starlight, ew! No! Bad dragon!" Brenna stammered, as drool stuck to her clothing and face. "For Thor's sake, you know how much I hate this!"

*Norse "I know! That's why I'm doing this!" Starlight replied, licking Brenna even more.

"Why, you mean little - not my hair! You know how long it takes for me to wash it!" Brenna protested. Saliva was dripping off Brenna's hair, and Starlight snuggled her with a big, smug grin on her face.

"So cute. Toothless, let's face it, human nerds are adorable," Starlight gushed.

"I know. Watch this," Toothless grinned, as he styled Hiccup's hair into a mohawk using only his (Toothless', not Hiccup's) saliva. Hiccup blushed at the things Toothless was doing with his hair.

"How do you get this stuff off you?" Hiccup asked, as Starlight attempted to braid Brenna's hair. Unfortunately, she couldn't completely release it from its bun prison due to a lack of opposable thumbs. "Do you use magic? Prepare a potion?"

"No, Hiccup, you don't do any of that, but there is something you can do," Brenna replied.

"What?" Hiccup asked.

"Take a bath, like a normal person," Brenna replied.

*Norse "You are adorable. Now, we're going to let you go, and this won't happen again unless this flippant behaviour continues," Starlight replied. "Come on." Brenna and Hiccup were shepherded back home, and both took a very grateful shower. Being licked felt uncomfortable, but washing off the saliva felt AMAZING. Brenna spent an awful lot of time washing her hair, which could be justified once you took in just how long it was.

It reached her calves. Yes, you read that right, her calves.

"And . . . all done!" Brenna sighed. "Now to get my clothes . . . where are my clothes?" She could hear Starlight giggle. "For Thor's sake, Starlight!" Brenna huffed, as she created a portal to her wardrobe, where she quickly grabbed her nightgown and pulled it through the other end of the portal. "Damned Night Fury," she huffed, as she stomped off to bed, drying herself with magic. "Doesn't know when to quit."

"And if you think she's bad, you should see her rider," Starlight chimed in.

"Shut up, Starlight."

"Love you too, nerd queen."
