A/N: Since owlmylove was enthusiastic, here it is!
The second time someone questioned Darcy’s background occcured after the team came back from an incident involving robots. Dr. Bruce Banner and Tony were entering the lab discussing (surprise, surprise) anti-electron collisions when they stopped short. Dr. Foster’s lab assistant was hunched over a workbench with a soldering iron in hand and a narrow object propped up in front of her.
Normally, they only ever saw her on a computer or shoving food at Dr. Foster (usually in the form of Pop-Tarts). Up until that point they would’ve bet good money she didn’t know what a soldering iron did, much less what it looked like. She hadn’t even noticed them walk in. Thin spires of smoke wafted away from her project as she referenced some sort of diagram spread out before her.
The two shared a look before walking towards her. The closer they got the more they realized she was muttering under her breath. Mostly it was broken sentences, and Dr. Banner could’ve sworn he heard her say something about a fez and bowties.
“Damn screwdriver!” she grumbled, nearly slamming the iron down. Pale fingers snatched the diagram and brought it close to her face. Bruce peered over her shoulder to see what she was working on when he caught sight of circular notations scrawled across a beat-up paper; they looked more like geometric doodles than anything else. The object was long with a bumpy end with a bluish light and a smooth handle. She still hadn’t noticed them as she growled, “He just had to make things difficult.”
“Uh, Darcy?” Bruce asked warily. She jumped and whirled around forcing both men to stumble backwards.
“Holy shit! Warn a girl will ya!” she exclaimed. Tony had moved in quickly and was already examining Darcy’s handiwork.
“What is this?” he asked. “A tinker toy?”
Her expression soured. “No!” she declared defiantly, pushing the billionaire back. “It was a gift, but I have to work for it apparently. Bastard probably thinks I won’t be able to do it; next time I see him I’m so tazing him.”
“A gift from whom?”Bruce questioned, maintaining a safe distance from the snarky assistant.
“A friend,” she answered, already focused on the object. A look of understanding flashed across Tony’s features so quickly Bruce thought he may have imagined it.
“Fish fingers?” Stark said. Darcy nodded, resuming her work. That seemed to be enough for him as he claimed a space on the other side of the lab, leaving Bruce to wonder what he’d missed.
He was lost in thought until Darcy claimed, “It’s pretty useful.”
“What?” he sputtered. She was facing him fully and holding the gadget up. She hopped off the metal stool and was on her way out when Bruce found his voice and asked, “Why?”
She stopped, Converse barely making a noise on the floor. She seemed thoughtful before replying, “Tasers don’t open doors or fix things and carrying keys and remembering codes is bullshit. “
He hadn’t the slightest idea what she meant, but several days later he realized she never carried keys anymore.
((Kinda meh but whatever. Lemme know what you think!))
