Kerry quirked her lips in a disbelieving smile but she didn't say anything else, instead going to intervene before Tony tried to fully recruit FitzSimmons, or just lock them away so Coulson couldn't have them back.

Coulson went onto the Bus, heading straight for FitzSimmons' lab. Even from outside the lab, he could see the three scientists having fun.

"Mr. Stark, kindly remember that you're not allowed to keep my science team as pets," he commented, walking in.

"I wouldn't keep them as pets, they're way too good to be pets, pet is the entire R&D department, I still don't know what I'm paying them to do. No, these two are much better. Not ScienceBros, 'cause that's Bruce, but Science-somethings, and I can offer them a better lab and probably less chance of getting shot at." Tony grinned.

"They belong to me," Coulson replied steadily. "By contract."

"Bah, contract, who cares? I can totally buy that." Tony grinned. It was tempting, but he was (probably) going to let them leave with Coulson. As long as they promised to come visit often.

"No," Coulson said.

"Oh, but sir--" Jemma started.

"Simmons, we can't constantly be here because Stark promises to feed you," Coulson replied. Although he could admit, realistically, that they would likely spend a lot of downtime at the tower anyways, to keep an eye on Clint and Natasha.

"I'll get a jet out to pick you up whenever you decide you need to get away from him," Tony promised with a grin. "Any time. Really. Ask Bruce, I picked him up in the middle of Idaho once, still don't know what he was doing there."

FitzSimmons both looked at Coulson hopefully, and Coulson just sighed.

"Don't count on it," he said.

Tony just grinned and waggled his eyebrows.

"Seriously. Science. Here. Any time."

"Stop trying to tempt my science team, Stark," Coulson said evenly.

"It's a great offer, Mr. Stark," Fitz said.

"Wonderful, truly," Simmons added.

"And we'll take you up on it as soon as we can."

"Open offer, just ring sometime before you walk in so I can have Jarvis buzz you through security." Tony grinned. "But if you really want to keep helping Agent Agent, here..."

"It's an opportunity we really can't pass up," Simmons pointed out. "As kind as your offer is, Mr. Stark, we should really stay with Agent Coulson."

"Bah." But Tony was grinning, clearly not offended. "Fine, fine."

"Your offer is really very generous," Fitz added. "We're honored, we really are."

"I know, I know." Tony waved them off. "Calm yourselves, I'm not about to get offended by that. You'll need to work a lot harder to piss me off."

"...Really?" Fitz asked, a bit baffled.

"Oh you two are so cute." Tony grinned. "Pepper regularly shoots me down and she's not nearly so nice about it."

FitzSimmons both looked a bit embarrassed, glancing at each other and then looking everywhere but at Tony.

Tony cackled a bit, and Kerry decided that was her time to swoop in.

"Okay, Stark, that's enough, go on, back to your lab. Shoo."

"We should really thank Agent Barton for introducing us," Simmons commented to Fitz, although she knew everyone could hear it. "Although I'm sure there was an ulterior motive, it was still nice."

"He's in the vents," Kerry told them. "You can just yell thanks and he'll hear you." She rolled her eyes at Barton and half-pushed Tony out.

"Oh that's frightening," Fitz muttered, glancing up at the ceiling. Coulson just sighed.

"You get to deal with him tonight, Coulson," Kerry's voice floated back to them before she and Tony left. She was grinning. Ha! Not her job tonight!

Coulson rolled his eyes.

"If I find a Roomba on my Bus when we leave tomorrow, I'm not going to be pleased," he said to the room at large. He knew Clint heard him.

By the time they were ready to go the next day, Kerry was a little more relaxed. She felt better knowing that Coulson was around if she and Avery needed help. Plus Tony wasn't being quite as bad as normal, which she counted as a plus.
