This idea has been lurking in my head for a while. Just a oneshot. Enjoy.
Ruffnut and Astrid were so different that hardly anybody who didn't know them could believe they were best friends. But it was their differences that brought them together. Astrid was a pretty girl with bright blue eyes and lovely blonde hair, but if you got her mad-it was best to sleep with one eye open. Ruffnut could make a grown man turn pale with fear with her harsh glare and her scuffles with her brother were hardly a secret to the village. However, Ruffnut loved flowers and trying out new hairstyles and other girly things nobody would suspect her of (except Astrid, her secret keeper).
This day, Ruffnut was sewing some cloth together while Astrid paced angrily back and forth across the room. She was fuming over Hiccup…again.
"It's just not natural! It just shouldn't happen!" she growled. Ruffnut glanced up.
"What shouldn't happen?"
"Hiccup!" Astrid screeched. And just like that, Ruffnut's imagination went wild. "He barely even touched that Nadder and everybody was fawning over him at dinner the other night!" Yes, that had been impressive to Ruffnut. She was one of the ones talking to Hiccup that night at dinner.
It had all started that day he had backed the Zippleback into the cage. Since then, Ruffnut's mind had been littered with thoughts of Hiccup, Hiccup, Hiccup. She had watched him at dinner that night out of the corner of her eye. He hadn't stayed long-wolfed down more food than she thought he was capable of and headed out again-but he had been the main topic of conversation amongst the teens. Everyone thought it was a one-time thing and that the Zipplebacks must've not liked the smell of the forge on Hiccup. Until he brought down the Gronckle, that is.
"More and more people from the village come out every week to watch him!" Astrid complain. "I don't think he's even used a weapon on them! Yet somehow, the dragons either quiver in fear or turn to mush when they get within ten feet of him!" That was what really impressed Ruffnut. He had managed to make a Gronckle turn into an overgrown kitten. That was when Ruffnut's thoughts when from intrigue to admiration. She'd see him in the village and she'd run at him with an almighty battle cry and tackle him to the ground.
"Ruff, what was that for?" Hiccup wheezed as he pushed himself back up from the dirt. Ruffnut shrugged and leaned in a little, smiling.
"That's just my way of saying 'Hello, and have a nice day!'" she explained in a husky, suggestive voice.
Tuffnut had snickered when he witnessed the incident. Really, that was Ruffnut's warped way of letting someone know she liked them. Since then, Ruffnut would tackle him on an almost daily basis. She also tried conversation-mainly asking him about what kind of work he had done lately in the shop and if he had any more inventions planned. There had also been an attempt at the more traditional flirting, but Hiccup had only asked if she had something in her eye when she batted her eyelashes at him.
Mrs. Ruffnut Haddock. Mrs. Hiccup Haddock. Mrs. Hiccup Horrendous Haddock the Third. Mr. and Mrs. Haddock. Mr. and Mrs. Hiccup Haddock. Hiccup and Ruffnut Haddock.
Now it seemed all Ruffnut did was have fantasies and make impossible plans about how she could get Hiccup and herself alone together. Hiccup and her, alone in the shop. Hiccup and her, staying up late to talk in the Great Hall. Ruffnut, taking Hiccup throwing him down on the ground and riding him like a-
"Are you even listening to me?" Astrid demanded shrilly. Ruffnut looked up to see her friend red-faced and looking murderous. She shrugged.
"Yeah, I heard. You don't like Hiccup and I think he's a stud muffin," she replied simply. Astrid let out a scream of frustration and sat down on the bench, face in her hands.
"What're you making anyway?" she asked after she had taken a few calming breaths. Ruffnut had just finished her work a few moments earlier. She smiled proudly.
"New clothes for some new dolls," she said, almost singing. Another little known fact about Ruffnut: she still had dolls that she dressed up. She slipped the last bit of clothing on to one of the two dolls she had on the table and held them up for Astrid to see. The doll in her right hand looked a lot like Ruffnut…wearing a dress. That never happened. The doll in her left hand…no. It couldn't be.
"It's Hiccup and I on our wedding day!" Ruffnut explained. Astrid turned purple.
"Ruffnut! Wake UP! It's HICCUP! HIC-CUP! He's the village screw-up! You've been tripping him since we could walk! You HATE him!" Now Ruffnut was mad.
"I've never hated Hiccup and you know it!" Ruffnut spat, standing up and getting right in Astrid's face. "Is he fun to mess with? Yes. Does he tend to make a few more mistakes than others? Yes. But I've never been intentionally mean to him. Even I know when to quit."
Astrid glared at her friend. "You only like him because he's winning in dragon training."
"And you're only jealous because you like him!" Ruffnut retorted. Astrid sputtered, unable to think of a response. Ruffnut continued. "Whenever somebody was too harsh on Hiccup you always went and beat the crap out of them. Every other guy hit on you while Hiccup kept his distance and did nice things for you. I know he was the one who made you your axe for your birthday! You've always liked him but you've always been better than him at everything so you can't stand that he's finally better than you at something. But most of all: you're mad that you might've blown your chance with him. You always criticized him and you probably just thought it was tough love. But when you blew up at him a couple weeks ago-that was it for him. He's hardly said two words to you since. Hiccup's given up on you and you can't stand it!"
Ruffnut stood there, chest heaving, glaring at her best friend. Astrid glared back with equal intensity. Without a word, Astrid stormed out of the house, slamming the door behind her. Ruffnut sighed and went back to her dolls. Astrid would come around and she'd realize she was wrong. Of course, that day would probably be when Ruffnut and Hiccup exchanged vows.
Hm…Mrs. Ruffnut Haddock…
I couldn't help but think during the movie that Astrid not only disliked not having anybody pay attention to her but maybe she was also upset that Hiccup wasn't paying much attention to her either. He always made attempts to be nice to her which she always brushed off. She did try and give him some constructive criticism at dinner after the first day of training with the Gronckle and even her blow up at him after fighting off the Nadder could just be interpreted as her trying to get him to realize he needs to get his head in the game. But still, her words were harsh so that might be a reason why she looked to see where he was going after the bonfire (Hiccup left without making any attempt to talk to her!) So while most of Astrid's rage was because Hiccup was better than her at something, I think a tiny bit of it may have been Astrid having some feelings for Hiccup. Just a theory.
