Tony snorted.

"It can be done," he replied. "I just need to make smarter arrows that can adjust according to wind and target." He held up the mangled pile of wires to emphasize the 'smarter arrows' bit.

"I didn't say it couldn't be done, just that there's no point," Sim pointed out. "I'm sure you'll figure it out. Should be fun to see the end result."

Tony made a vague noise of agreement and immersed himself in the project again. He wanted to get the working prototype done.

Sim found a place to perch with her tea, just watching him for the moment. She did glance over at Bruce and quirk an eyebrow to ask if it was okay if she stayed for a little bit.

Bruce had already made his way over to his section of the workshop and sat down. There was a pencil already in his hand and a notebook in front of him, and he was already scribbling away at a few calculations.

Sim snorted quietly at the two and settled in to just watch for a bit. And when Dummy came whirring over to say hi, she didn't even freak out, just grinned.

Tony and Bruce both glanced over from time to time, making sure Sim wasn't getting into any trouble while she was left to her own devices. A Roomba whirred by, and Bruce habitually dropped a handful of paper hole-punches for the thing to eat.

Sim saw that and then grinned slowly. She gathered up a few pieces of trash and threw them around the room for the Roomba to eat, grinning like a loon.

"The fabrication units might have some leftover metal shavings," Tony commented without looking up. "They can't get rid of it themselves."

"Gotcha." Sim hopped off her seat and went to go empty all the metal shavings out onto the floor. "This is kinda fun."

"I'd say don't spoil them, but Clint already spoiled them beyond any hope of redemption, so spoil away," Tony said. He finally set down the prototype, rubbed his eyes a bit, and took a sip of his now-cold coffee.

"They're cute," Sim said with a grin, watching them zoom around after the trash she was throwing for them. "You want some fresh coffee?"

"How is that even a question?" Tony asked. "'Do I want fresh coffee,' I always want fresh coffee, that is a fact of life around here, clearly you haven't been here long enough." And he had to rectify that immediately.

"Well it's been all of four hours," Sim pointed out dryly. "Although I should have guessed since there's a coffee machine down here too."

"Tony would put a coffee machine in every room, if we let him," Bruce commented from his part of the workshop.

"Lies," Tony immediately protested. Bruce just raised an eyebrow and Tony sighed and rolled his eyes again. "Fine. But only one of them would be like Spike."

"I'm sorry, but you can't just recreate Spike, he's too awesome to recreate," Sim said. "And yes, I have met him. And Calcifer. I love Calcifer, and whoever named him gets goodies for a year."

Tony snorted.

"That was Coulson," he said. "The nerd."

"Goodies for a year," Sim said with a grin. "Free goodies, whatever he wants."

"What, and not us?" Tony asked with a mock pout. "I made the toaster, don't I get goodies for that?"

"Well, maybe," Sim said with a brief grin. "I suppose that deserves a few goodies too."

Tony grinned triumphantly.

"Ha, I knew it," he said. "I deserve goodies too, you definitely need to make some."

"What kind of goodies do you want?" Sim watched him, her eyes keen.

"I don't know," Tony said, waving a hand. "Surprise me. That's what Jarvis does."

"Oh a surprise. That's more fun." Sim grinned. "I could go work on that."

"You do that," Tony said, stretching a bit. He picked up one of his tools again, intent on getting back to his project. He wasn't going to be done until it worked.
