This a Fanfic! That means I don't own, you don't sue.
This is a movie centric fanfic mainly focused one line of Tony's. "Let's face it, this is not the worst thing you've caught me doing."
Pepper was drinking her coffee and trying to process what she'd seen yesterday, was it really just yesterday? Her boss, the man she'd watched and helped for years, wearing some weirdo suit that was riddled with bullet holes. And the one thing he'd said that wouldn't leave her mind.
"Let's face it, this is not the worst thing you've caught me doing."
No explanations, no nothing. Later she'd found out more but really, absolutely nothing? From Tony? Usually he couldn't stop talking about the cool stuff he'd done with his cars or the new microchip he was working on that make something or other work that much better. And the fact that he wasn't talking worried her, of course she knew everything now, right down to how many of his weapons he'd seen in that camp. She could understand his reasons for going back there, but her mind was inexorably drawn to the past, to the other "Worst things" she'd caught him doing.
There was the time when he'd gotten himself absolutely covered in, well she couldn't describe any better than pink goo, but it was hilarious, even Jarvis was laughing. Then the numerous women that she'd, ahem, walked in on, though she admitted to herself that sometimes that was on purpose. Her personal favorite, and this actually was an accident, was when she'd gone to get the lady of the hour from bed and speed her on her way only to find that her boss was tied up and butt naked. She'd been shocked for about thirty seconds then had to run into the hallway for five solid minutes before she could regain her composure enough to re-enter the room. Apparently the lady he'd propositioned had rather, unusual taste in pleasures.
Pepper smiled into her coffee as her boss went through his morning routine of arguing with Jarvis. The one thing she couldn't figure out was, where had that lady gotten the rope?
