Both Hiccup and Caverna slept through the night and well into the morning, only to be woken up by their dragon prodding the pair of them so that they could go to the dragon academy. Hiccup woke up first with a groan and they looked around finding themselves in their rooms, though neither of them remembered how they got there in the first place, but they let it slide. Getting up, they both threw their clothes on and ran downstairs; finding some porridge on the stove, and Caverna had Snowcap light the fire to warm it, as Hiccup and Toothless set the table. Caverna served two bowls of porridge and set them on the table as Hiccup fed the dragons. When the teens both sat down at the table, Caverna found that Hiccup was looking at her in a rather peculiar way as he ate.
"What's on your mind?" She asked.
"Nothing really, I guess that I'm just tired, we did have a rather late night – slash – really early morning fight earlier." He told her.
Caverna laughed. "Yeah, we did." She smiled, finishing her porridge, and as they threw their bowls into the wash basin to clean later, they ran outside with their dragons following and as they mounted them, they flew off towards the Dragon Academy. As they flew, they both looked around at the village, everyone seemed oblivious to what had occurred the previous night and Caverna looked at him.
"It's like nothing's happened." She told him.
"Yeah, I know." Hiccup sighed.
They flew together, mainly in silence, and when they reached the dragon academy, Hiccup walked round to her and helped her off the dragon, but this caused her to laugh at him, before they looked around and they found Astrid, Fishlegs and Snotlout all huddled up together.
"Um, guys what's going on?" Hiccup asked them as he walked over, causing the group to suddenly turn to face him, pushing something behind their backs.
"What are you guys hiding?" Caverna asked them.
"Nothing." They chorused.
"Where are the twins?" Fishlegs suddenly asked, and they all looked around, though whilst Caverna and Hiccup's attentions were on locating the twins, Fishlegs, Snotlout and Astrid all hid whatever was behind their backs in their saddlebags.
"So, what are we learning today?" Astrid asked as the twins turned up.
"Well, Caverna is going to take this lesson today, and then tomorrow, we will be going on a residential lesson." Hiccup explained.
"My lesson is going to be about finding a call for your dragon, and I will tell you about the residential trip after the lesson." Caverna told them.
"Phh, why would we need a call?" Snotlout asked.
"In case you are separated from your dragon, and you need them." Caverna told them. "For example..." She looked at Snowcap and made a gesture to her, watching her nod and fly off, out of the arena, before she looked at the other Viking teens. "When Snowcap and I are separated, I can use two different alls to bring her back, the whistle which is the one I frequently use, or the call of a night fury."
"You can actually mimic the call of a night fury?" Fishlegs asked suddenly excited.
Caverna nodded, and she suddenly let out a loud sound, which mimicked that of a night fury, and soon after a call was heard and Snowcap flew back into the arena and up to her rider.
"Good girl." Caverna praised and she scratched Snowcap's head before she looked at the teens. "Who wants to try first?"
After a few minutes, everyone was practicing their calls, with Caverna leaning against Snowcap's side as she lounged in the cool winter sun. Caverna watched the group and she noticed Hiccup and Toothless were doing quite well, as was Astrid and Stormfly, in fact everyone but Snotlout and Hookfang, who were just lounging around. With a sigh, she walked over to him.
"Snotlout, why aren't you taking part?" She asked him as she walked over.
"Because Hookfang and I don't need to, we are both really in tune with each other as it is."
Caverna looked at him with a look that oozed disbelief. "Alright then, show me."
"No problem." He walked away from her and his dragon to the other side of the arena, and he looked at Hookfang. "Hookfang, here!" He barked, causing the dragon to simply ignore him and move to lie in the sun.
"Hey, you stupid reptile, I said, come here!" Snotlout shouted again.
"Snotlout he isn't going to come to you." She told him, walking over to him. "Try a whistle."
"Uh, yeah and how am I supposed to do that?" He asked in disbelief.
"Like this." She put her fingers to her mouth and suddenly whistled Snowcap running over, sitting at hr rider's side.
Snowcap's reaction ended up rubbing Hookfang the wrong way and he sneered at the younger dragon.
"Lap dog." He sneered.
"Shut it overgrown space warmer." She told him with a growl.
At the growl, Hookfang went for her, and he ended up catching her, throwing her into a wall.
"Snowcap!" Toothless ran towards the two fighting dragons, just as Stormfly and Meatlug did and the three dragons tried to protect her from Hookfang.
"Snotlout, get your dragon under control!" Astrid shouted.
"No way, Snowcap could do with going a few rounds." Snotlout told her, though he suddenly regretted it as Caverna's fist hit his jaw.
As Snotlout was trying to pick himself up from the floor, Caverna whistled and Hookfang started towards her, though once he was within range, she grabbed his horns and threw his head to the ground, standing over him.
"Don't you dare." She warned the dragon, who looked up at her in shock that she could have threw him to the floor like she did and then confusion as to why his rider wasn't helping him. Snotlout watched them, and when Caverna walked away, did he go to his dragon.
"Easy bud, calm down." Snotlout told his dragon, and they both watched as Snowcap and Toothless curled up together.
When it got to the end of the lesson, Caverna stood in front of the group with Hiccup beside her.
"Right, now as we mentioned earlier, we have a residential training exercise next week, it will last for the whole weekend, so we will still have time to help prepare for our annual Snoggletogg holiday." Hiccup told them, though no one noticed the curious look that Hiccup gave her at the mention of Snoggletogg. "Now Caverna is going to explain what will happen."
Caverna looked at the group. "Okay, for this residential, we will be going to dragon island, and just so you know it wasn't just my idea, but Hiccup and Astrid's too, so we will have a mixture of survival training, dragon training and dragon bonding."
"Uh, how are we supposed to bond with our dragons?" Ruffnut asked them.
"It will all be explained properly next week, now come on, we'd all best head home, I'm starving." Caverna told her brother playfully, who simply laughed.
"Are you coming for dinner Astrid?" Hiccup asked.
"Who's cooking?" She asked.
"Hiccup." Caverna told her, "I'm just cutting bread." With a laugh, the three of them mounted their dragons and flew off.
Snotlout stayed in the arena for a little longer, testing his jaw and he noticed Fishlegs was still there, drawing something on a piece of parchment.
"What are you doing?"
"N-nothing." He stuttered, trying to hide the piece of parchment behind his back, but Snotlout snatched it from his hand before he could.
On the piece of parchment, was a drawing of what looked like, well Snotlout had no idea what it was to be exact, but he knew who it was for.
"And you really think she's going to like this?" Snotlout asked him, his tone was snarky yet his big ego showed through it. "Caverna won't like something that meek, she's a chief's daughter she deserves jewels and a proper man to be with her.
"You don't even know what it is." Fishlegs told him as he stood up. "Anyway, what have you got her that you think she will love soo much?"
"It's a silver hairbrush and mirror." He told him proudly. "Along with a ruby necklace."
Fishlegs looked at him, inside he felt gutted that he hadn't thought of something better to give to her, but he tried not to let it show in front of Snotlout. "Yeah, but it still won't impress her, after all, I was her boyfriend when she first came here."
"Yeah, and we can all see how that went." Snotlout laughed. "Face it, you had your chance 'Legs, and you blew it, dramatically." Snotlout climbed on his dragon. "Now if you don't mind, I have to go home and finish off the necklace." He told him, flying off out of the arena.
Meanwhile, in the Great Hall, Stoick and Gobber were talking whilst enjoying a bite to eat and a mug of watered down mead.
"What's the matter Stoick, you look depressed." Gobber asked after he had seen his friend staring at his food for over an hour.
"Nothing is the matter Gobber." Stoick sighed.
"Stoick..."
"Fine, do you remember when we went to Caverna's old village, and I went off to speak to Helena and Brock?"
"Yes..."
"Well, they confirmed it, Caverna is actually my biological daughter, when she was taken, Val made her way to that island where she gave birth but left the baby in the care of Brock and Helena." Stoick told him, looking over at his friend who was just looking at him.
"Do the kids know?" Gobber asked, pushing his food away, this was more important right now.
"No, I would have told them last night, but I found them curled up together by the fire with their dragons." Stoick told him. "I'm going to tell them tonight when I go home."
"Why don't we go now, they are probably home having dinner right about now." Gobber told him as he stood up, and Stoick sighed doing the same. The two men walked in partial silence and they found Snowcap, Toothless and Stormfly lying in what sun they could get outside of the house and there was laughter coming from inside.
Meanwhile, inside Hiccup, Caverna and Astrid were sitting around the table, enjoying some stew that Hiccup had made and they were looking over a list on a piece of parchment.
"You know Astrid, Hiccup would make the perfect househusband, I mean, he cooks, he cleans, he cares for those he loves, what else does a housewife do that h doesn't?" Caverna asked playfully, which ended up with laughter and Hiccup playfully shoving her off her chair and onto the floor.
"Come on you two, be serious." Astrid told them, though even she was laughing as she watched Caverna pick herself up. "We need to get this list sorted for the residential next week."
"Relax Astrid; I think we've covered everything." Caverna told her, looking over the list as she finished her food, and gave her bowl to Hiccup who went to wash them.
"I think that to, but I also feel like we're missing something." Astrid sighed. "Maybe if I sleep on it I'll think of it."
"Yeah maybe." Caverna laughed.
Hiccup laughed as he joined them and they all turned around as they heard the door open and Stoick the Vast and Gobber the Belch stood there.
"Hey dad, hey Gobber." Hiccup greeted.
"Hi dad." Caverna smiled. "Hi Gobber."
"Hello you two, and hello Astrid." Stoick smiled as he walked inside and Astrid gave him a nod, before Caverna spoke.
"Would you like some stew dad?" Caverna asked him. "Hiccup made it, and he made plenty of it."
"I'll have some for supper, Gobber I had lunch in the Great Hall today." Stoick told them. "I actually need to talk to you two."
"Would you like me to leave, Sir?" Astrid asked.
"No Astrid, you can stay." Stoick told her, before he sat in his large armchair and gestured for the children to sit before him.
When Caverna and Hiccup were sat in front of him on the floor, he looked at them, and now they were both lit by the fire and sitting side by side, did he realise that they were both even more similar that people told him.
"What is it dad?" Caverna asked.
"I found out something whilst I was on your old island Caverna."
"What was it dad?" Hiccup asked him.
"You mother..." He almost stopped at seeing the look of loss on his son's face and how Caverna looked at the floor, but he continued, he needed to tell them. "When she was taken, she was pregnant; she made her way to that tribe where she gave birth...To a girl..."
Caverna looked up at feeling everyone's eyes on her. "So, what does this mean?" She asked Stoick.
"It means that you and Hiccup are actually related, you're biological brother and sister, and I'm your real father." Stoick told her.
Caverna soon found herself on her feet, just as Hiccup did and they looked at each other, before they both suddenly beamed and hugged each other tightly. The sight had Stoick, Gobber and Astrid all tearing up as they watched the two siblings. When they eventually pulled away, through Caverna's hold being too tight and Hiccup finding it hard to breathe, they shared a happy laugh.
"Now I have something to ask all of you." Caverna told them.
"Anything." Stoick told hr standing up.
"What's Snoggletogg?" She asked and everyone looked at her in surprise, before they started to laugh and that was how they ended their day, laughter and fun with a few explanation thrown in for good measure.
