Here goes the story behind my rules fic! I was really surprised at the enthusiasm for this story so I hope I haven't disappointed anyone. J

Chapter One

Cassandra James had cleaned for some pretty crazy clients. There had been that crazy cat lady in Jamaica, the old man in Germany who thought she was his wife… That was weird. But the people she had been working for, for the past 2 months were beyond weird.

As Cassandra walked towards the elevator the security guards gave her the usual encouraging nods and sympathetic smiles. Because you can be damn sure that what awaits her upstairs is the usual chaos.

Cassandra smiles as she remembers her first day. She'd come away a little shell shocked but returned every day since with a kind of grim determination.

"Where the hell is my phone?" Tony was yelling from the kitchen. Cassandra sighed, took a deep breath and picked up Tony's phone from the couch.

"You know for a genius you sure are stupid." She observed casually as she handed him the phone.

"Yeah, yeah. Whatever. I need you to prepare one of the rooms in the Avengers hallway. Thor's arriving today." Cassandra nodded and headed to the chosen room. Her friends had been all excited for her when she had gotten the job, but to her it was just another job. She wasn't all that interested in meeting the god. But, from all the others had said of him, Thor was the opposite to Tony in all respects. And if he was no genius, billionaire, playboy, philanthropist then Cass figured they'd get along fine. One Tony was more than enough.

But when Tony came down from the roof with a sulky expression on his face Cass knew something was up. Tony didn't sulk. He argued, slammed doors, but he never sulked.

"What's up?"

"Why don't you ask Thor?" Uh oh. Thor had only been here a minute or so, what the hell could he have possibly done to piss Tony off so early in his arrival?

The answer to her question was immediately made clear by the 6 feet 4 inches of pure gorgeousness that was following Thor. Upon coming to live at Stark Tower Thor had decided that his little brother needed to see how mortals were not beneath them.

Cass went off to prepare Loki's room and when she went to get some bed sheets found the missing Tony in the airing cupboard.

"Oh for goodness sake! Tony pull yourself together! Honestly! Get down there and rise above it!" She then proceeded to yank him out of the airing cupboard and shove him downstairs. Cass had no patience where sulkers were concerned.

The rest of the day passed without incident. Cass made them spaghetti bolognese, then headed home with another headache. Looks like the painkillers are coming out again tonight, she thought as she opened the blue front door to her one bedroom apartment a block from Stark Tower. And I have to get up early tomorrow morning to get bloody poptarts for Thor! Thor had been particularly upset to find that there were absolutely no poptarts in the Tower.

Beep! Beep! Bee-! That was the snooze alarm going off- Wait! The snooze alarm! Cass shot out of bed and threw herself towards the wardrobe. Hurtling down the road to a corner shop she practically chucked the money at the cashier and yelled,

"Sorry late for work!"

Cass collapsed on the living room floor gasping for breath. Nobody even noticed she was late. That is, nobody except Loki, who followed her from room to room lecturing.

"Tardiness is not tolerated on Asguard. You'd be flogged for being late you know." Eventually Cass's patience wore thin and she turned around and glared at him.

"I couldn't give a damn about what you do to people who are late to work on Asguard! This is Midguard and we do things differently here!" She then turned and carried on cleaning. Loki was so astonished that he went silent and left the room. She wasn't sure whether this was because he hadn't realised she knew the Asguardian term for Earth or because for the first time in his life he'd met somebody who actually didn't give flying fuck about his opinion. Oh well, he'll have to get used to it, she thought. Tony wasn't going to hide it either, she knew that much.

"Lady Cassandra?" Cass sighed in exasperation. She had been repeatedly telling Thor all day to call her Cass but his polite Asguardian side was not letting him do so.

"Yes Thor?"

"Loki says he will not come down until you go and apologise to him for shouting at him earlier."

"Well looks like he's missing out on roast chicken then doesn't it?" Tony snorted. Steve and Bruce raised their eyebrows and Clint high fived her. Natasha laughed.

"Lady Cassandra I don't think you realise how unstable Loki is. He might hurt you if you do not apologise." Thor sounded almost childlike in his desperation to keep her from harm. But Cass was no pushover, Loki was gonna have to learn that at some point. Better he learned it sooner rather than later.

Meanwhile Loki was sat on his bed waiting for her to apologise, he was so sure she would. But when he heard the chairs scraping on the floor as everybody sat down to eat it began to dawn on him that maybe she wasn't sorry about what she'd said after all. 10 minutes later Loki made his way downstairs.

"Hunger win out?" Cass asked as she handed him his dinner, with a smirk.

Tony and Clint burst out laughing, Natasha snorted into her dinner and Steve and Bruce tried to hide their smiles.

"Oh Thor, I got you some poptarts. They're in the cupboard." Thor beamed at her and practically skipped to the cupboard.

That night as Cass snuggled down in bed she thought, It's official. Life just got weird.

Poor Cass couldn't know how right she was.
