When they eventually reached Berk, after taking around six days to get back since they needed more and more stops as neither of them had fully healed. Because of this, when they eventually landed on Berk, Snowcap collapsed to the ground, her wound looking red raw and she was exhausted.
"Snowcap?" Caverna knelt down on the ground next to her dragon as Toothless and Stormfly ran over.
"Is she alright?" Stoick asked as he joined her with the others.
"She's exhausted and her wound isn't being much of a help." Caverna sighed, brushing her hand to her dragon's scales.
"Come on, we'll take her somewhere to rest." Stoick told her and with the help of some other Vikings, he carried the dragon towards the Great Hall.
When they had gone, Toothless suddenly scooped Caverna up onto his back and she laughed. "Toothless, what are you doing?"
"He's trying to make you feel better by giving you a piggy back ride." Hiccup told her as he walked alongside Toothless, with Astrid following as she rode her dragon beside them.
"Awe, Toothless, thank you." She stroked the dragon's head and he gave her a pleased noise.
Toothless brought her to Gobber's forge and the two limbed Viking stumbled out of the forge towards them.
"Ah, Hiccup, Astrid, glad you're both back safe, and you too Toothless and Stormfly." He smiled, before he looked at Caverna. "And its good t see you too Caverna."
"Thank you Gobber." She smiled.
"Now, what can I do for you?" He asked the group as Hiccup helped Astrid off of Stormfly's back.
"We need you to build an extra room onto mine and my dad's hut, Caverna will be living with us, as a child of my dad."
"Ah right." Gobber told him. "I'll get right on it."
"Great." Hiccup smiled. "Come on, let's go and check on Snowcap."
He walked with everyone up towards the Great Hall, where they were joined by Fishlegs, Snotlout and the twins and Caverna slid off of Toothless' back and she walked in ahead of them. She spotted Snowcap curled up in a corner with a fire roaring in front of her but as she was about to go to her, she was pushed out of the way and onto the floor by Toothless.
"Toothless, easy there bud, remember Snowcap isn't the only one who's injured, her rider is too." Hiccup told his dragon as he helped Caverna to her feet.
"It's fine Hiccup." Caverna told him. "You would do the same if Astrid was injured and needed you."
"But still, he shouldn't just push people out of the way like that, especially not those who are still suffering from wounds." Hiccup told her.
"Well, please try and be nice to him about it, you know he worries and any way, I am unharmed." Caverna told them as she accepted his help to stand up again.
"Ah, Caverna there you are." Stoick boomed and he walked over to the small group of teenagers, though he was followed by Gobber and a thin sickly looking man with a staff.
"I see that you have brought another pathetic looking dragon here." The old man suddenly spoke; his voice croaked and sounded disbelieving as he pointed his staff at Toothless and Snowcap, only to have Toothless growl in warning.
"Toothless, calm down bud she's okay." Hiccup told him, and at his rider's words, he did calm down, nuzzling the dragon beside him as she slept.
"Caverna, this is Mildew, one of our oldest residents at Berk. Mildew, this is Caverna, the now adopted sister to Hiccup." Stoick introduced them, though Mildew didn't look pleased about it, even as Caverna bowed her head in respect.
"Why bring another brat here Stoick, when we hardly have enough food for ourselves this winter." Mildew carried on, now pointing his staff at Caverna.
"I've gone without before Fishbone, losing out won't bother me." Caverna told him.
"Fishbone? Well that's rich coming from a washed up rejected, disinherited like sprout like you." He told her, though he soon found one of Caverna's swords almost cutting off his head with how close she had gotten it.
"You know, I'm not going to waste my energy on someone who looks as though he has been buried for months only to have been brought back to reimburse his hatred for dragons."
Her words caused everyone around them, but Mildew, to laugh though Mildew simply uttered and walked away, glaring at the dragons and Caverna.
When it grew dark, Stoick led Hiccup and Caverna back towards his hut and they looked around when they got inside.
"Caverna, for now you can sleep in Hiccup's room, Hiccup will sleep down here." Stoick told her.
"That would be fine, but if Hiccup would rather sleep in his own bed, then I could sleep down here." Caverna told them.
Hiccup looked at the pair of them as they looked at him. "How about, we go upstairs and sit on my bed upstairs and whoever falls asleep first gets to stay there."
"Sounds fair enough." Caverna shrugged and the two teens ran upstairs, well hobbled in Hiccup's case, and they ended up collapsing in laughter on the bed.
They lay about laughing for a while, before there was a heavy knock on the door, and it was Stoick who opened the door and poked his head through.
"Sorry to interrupt, but I thought that you might want a change of clothes, for day and night." Stoick told her, nodding to the pile of clothes in his arms. "These belonged to my wife, when we first met; I figured that they might fit you."
Caverna walked over and she smiled, taking the clothes. "Thank you Stoick."
"Caverna, you can call me father, if you wanted, since you are my adopted daughter." He told her.
"Okay then, father." She smiled, and both of them left to allow her to change and she dressed in a long nightshirt, which covered from her shoulders to her knees, before she and Hiccup sat up most of the night talking.
"So, how did you get a suit like that?" He nodded to her suit that was folded on a chair with the jacket hung over the back of the chair.
Caverna looked at him. "I made it." She told him. "I made my first one when I started dragon riding, I was around ten years old then and I've made bigger ones each time I've grown or they've been ruined."
"Ah, do you have to wear things underneath them like you wear your tunic, or can you get away without?"
"You need to, the leather feels horribly uncomfortable without, and anyway the jacket is more of a flight suit to keep the body warm." She told him. "I could make you one if you want."
"Would you, I mean, that would be pretty cool if you could?" Hiccup beamed.
"Of course I will." She smiled. "We're brother and sister now, it would be awesome." She told him with a laugh. "Anyway, I have to make myself a new one now that I'm part of a new family, our crests are different."
Hiccup smiled. "Welcome to the family, Caverna." He told her, before they both lay back on the bed and they ended up falling asleep.
