Loki/Darcy – Bonding Over Their Love Of Tony

My first ever MCU prompt fill! Takes place in the same AU as my "Shifting Views" story, in which Frostiron happens, and Darcy and Tony have decided that the pair of them are honorary siblings (though Darcy has enough brothers already, thank you very much) and occasionally hang out together as such.


Loki watched intently as Darcy toasted some mini-marshmellows threaded on a toothpick with the aid of a lighter, before setting it across one of a pair of shot glasses sitting on the bar, the other already topped with its own toothpick of same. She smiled triumphantly, and slid one across to him. He picked it up, looking at the dark layer at the bottom of the otherwise creamy-looking concoction. "And what is this one called?" he asked, enunciating carefully though he was far from drunk, the drinks of Midgard being comparatively mild compared to those of Asgard. Still, they had been at this for several hours now, ever since the Avengers had been called out for a fight, Tony having to abandon his girl's night in with Darcy.

"It's a s'mores shot," Darcy explained, then picked up the toothpick off of hers, stripping the soft marshmallows off with her teeth and washing them down with the liqueur, before licking the rim of graham cracker crumbs off the glass. "Delicious."

"If you say so," Loki said, a touch dubiously, then imitated her example, eyebrows rising a little in surprise. "Sweet," he said, and stuck his tongue into the glass to lick the remains of the tasty liqueur off the inside of the glass.

"Dude," Darcy exclaimed, her eyes widening. "You can't just go and do things like that. Not unless you're trying to give me ideas, and I don't think Tony would like you giving me ideas. I think he might be the jealous type."

Loki grinned, and made a show of licking out the glass again. "No, I'm the jealous type," he said pointedly. "Though if you're suggesting I should do this in front of him," he paused for a moment to chase the last drop of the dark liqueur out of the bottom of the glass. "Well, I'll consider it," he said, and grinned at her.

Darcy laughed, and threw a mini-marshmallow at him, bouncing it off the middle of his forehead. "I would pay money to see his reaction," she said. "Another?"

"What is the bottom layer of this? I like it very much."

"Dark chocolate liqueur. Want some straight? Or no, even better, where'd that vanilla ice cream get to, we can have some ice cream drizzled with it."

Which is how Loki found himself ensconced on the couch with Darcy a few minutes later, holding a large bowl of ice cream drowned in chocolate liqueur, Darcy leaning companionably against his shoulder and making humming sounds of pleasure as she ate a spoonful from the shared dish.

"We need a movie to go with this," she told him. "Preferably something animated. Do you like Ghibli films? Has Tony shown you them yet?"

"Yes, and yes, as well as everything Pixar and a number of the Disney movies," he informed her. "I sometimes think he's in a second childhood," he added thoughtfully, before taking another spoonful of ice cream for himself.

Darcy laughed. "I don't think he's ever really left his childhood behind," she said in a confiding tone, then frowned. "Well, except he didn't really have much of a childhood, did he? More like he was a little adult until after his parents died, and only since then has had a chance to let his inner child out to play."

"Mmmm. Perhaps," Loki agreed. "He rarely talks of his childhood to me."

"He rarely talks of it to anyone," Darcy pointed out, and fell silent for a moment, sitting there with her spoon held in her mouth and a thoughtful expression on her face, before pulling it out and pointing the bowl of it at him. "You're good for him, you know."

Loki glanced away, uncomfortable. "He's good to me. Better than I have any right to."

"I dunno if I can argue with that, you were kind of an ass at first," Darcy agreed, unsurprising considering her friendship with his... with Thor. "But you're good for each other."

Loki forced himself to smile. Talking of his relationship with Tony always made him feel uncomfortable; he kept expecting it to go wrong, though so far they'd managed to keep it going without too much drama. "You're good for him too," he told her. "He needed a good friend."

"I'm just one friend of many," she pointed out, looking self-conscious. "Pepper and Rhodey are his best friends..."

"And both of them are very busy and only rarely here," Loki pointed out. "You're the only friend of his I know of that he has named an honorary sibling. He is always... happier, more balanced, after these days out or nights in with you."

Darcy smiled, almost shyly. "I do have fun treating him like a sibling. Not that I really needed any more, with three brothers already, but..."

"But Tony certainly didn't have any experience of having a sibling, until he adopted you as one," Loki said, and smiled crookedly at her. "Proof that adoption is not always a bad thing."

"No, it's not," Darcy agreed, and leaned her head on his shoulder for a moment. "He makes the best honorary big sister ever. And I'm not just saying that because of the shopping sprees we go on together," she added stoutly, frowning slightly.

Loki smiled. "I know it's not his money that won you as his friend," he assured her, then thought for a moment, feeling oddly tentative when he spoke again. "Perhaps... maybe one of the next times you two go out shopping, I could tag along too?"

"Oooo, in your female form? That would be wicked," Darcy exclaimed enthusiastically. "You're so gorgeous when you go fem, like a fashion model. We could have so much fun... we could gang up on him. And seeing him with both of us together would drive the paparazzi into fits. Also, we could buy all the shoes. All. The. Freakin'. Shoes. You need some Louboutins of your own."

Loki smiled. "That could be enjoyable. Though I think... there was that brand you like to tease Thor over? I'd like some of those," he said firmly.

"Miu-Miu's? Awesome idea. I know just the pair for you," she said, smiling. "This is so going to happen. Me, you, Tony, and sisterhood."
