When Thor fell from the sky and Jane ran him over, Darcy wasn't startled at all. She had, after all, attended a school where the teachers tying students by their ankles to the tractor and driving around the grounds dragging them behind them was the norm. But then he acted like a crazy hobo, and she reacted like a typical St. Trinian's girl—shoot first, as questions later. More specifically, she tazed him with the special, MI7 regulation tazer that Kelly had smuggled her when she had announced her intentions to go back to the states and study politics in Virginia.

Jane shrieked at her, and she was reminded, oh, yeah, the way that we do things isn't actually normal, and Jane would have probably been eaten alive at St. Trinian's—not that there was anything wrong with that, St. Trinian's wasn't for everybody, and Jane was still her American bestie—American because a bunch of British people came before her on that totem pole—the St. Trinian's girls had been through things together that had forged a bond that nothing could weaken, and Jane could never really hope to compete.

So they hauled Thor into the back of the van, something that Darcy was rather adept at, since she had plenty of experience hauling around unconscious men that were considerably bigger than her thanks to her various high school adventures, and took him to the hospital.

Which was weird for her, since St. Trinian's girls didn't usually bother with the hospital unless it was serious shit, and this guy looked mostly fine.

But Jane checked him in and he was sedated, mostly because he woke up and tried to kill a bunch of nurses, and then went on their way. But then Darcy thought that maybe Jane would have made a better St. Trinian's girl than she had thought, because Jane decided that Thor was her greatest lead since... like, ever, and marched back to the hospital to find him—and promptly run him over. Again.

Then the government misappropriated their things, and took her IPod, she nearly called the girls to battalion over it and steal it back, but then Jane got distracted by their apparently real live Norse God, and then there was the big robot that nearly levelled the town and Jane disappeared.

Yay!

After Thor left, things settled into a somewhat comfortable pattern—Darcy made coffee and poptarts and tried to periodically talk Jane into subsisting on something more than just that, wrangled her to bed when she fell asleep at her workbench, every three days or so, and filed papers. She also entertained the pet SHIELD agent.

Barton was his name. Agent Clinton Francis Barton, he told her after they got drunk for the first time. He had biceps of steel, abs like you wouldn't believe, and a skin tight Kevlar sleeveless suit that showcased both to maximum perfection. He shot with a bow and arrow, and as he said it 'I was just good enough at the beginning of my career that they were willing to overlook my preference for a weapon that went out of style centuries ago'. As it stood, once he had warmed up to her and stopped being secret agent man, she had made the best friend that she had ever had.

Both of their minds worked in the same frightening way. They were both obsessed with internet memes and poptarts, and they both lived off of coffee and still slept all day when they had the chance. And Darcy nearly brained herself with a spatula when her stupid, schoolgirl crush came in and threatened to ruin the best friendship that she had had since St. Trinian's. Sure, they flirted. Darcy was a flirty person, and Clint seemed that way too. That was how she interacted with people—girls, guys, it didn't matter much.

Of course, neither of them really had much in the way of impulse control, which was how they ended up in bed together. And then bed turned into fuck buddies, and fuck buddies turned into relationship, and Darcy still wasn't really sure how it had happened.

But then Clint got called off mission. He was sent to some classified place and Darcy couldn't hear from him, and that was the abrupt end of that. She tried not to be broken-hearted, since he hadn't actually said that it was over, and also because Jane was more than providing the broken-hearted vibes without Darcy adding to the club. It didn't help that Erik left around the same time.

Then they were being shipped to Tromso. And New York was being invaded by aliens. And then they were relocating to Stark Tower, and Thor was coming back and... incoming happy ending. Except that ending meant the end, right, and this wasn't an end.

Suddenly, she was being promoted, because, oh! Phil isn't dead, but he needs a new assistant because The Avengers are too much to handle without one, and then assistant goes to Public Relations Manager, when the Avengers got four of them to have extended mental breakdowns and resign within two months, and Darcy was the only one who could last. And then they couldn't have the PR manager be someone's assistant at the same time, so they promoted her to PR Manager and Assistant Non-Military Handler, or, as Tony says, She Who Must Be Obeyed.

And her and Clint figured their shit out, and everything was going to be good. And then Kelly called. And Darcy was going to risk it all, because she was a St. Trinian's girl first, and that was what St. Trinian's girls did.
