That was good to hear, at least, that Peggy hadn't fallen victim to some unknown substance. Steve wouldn't have wished that on his worst enemy, let alone someone important to him. He hadn't been overly cognizant of it at the time, but in retrospect, it was obvious how out of his own control he'd been. If Peggy had given him the slightest hint that she was willing to take him to bed last night, he'd have gone, no hesitation, and that wasn't what Steve wanted for the two of them. Not when they'd already spent so much time waiting. He wanted to do things right, wanted to take her to dinner, take her dancing, even, hold her hand and all those other little steps he'd never gotten to take before.
Steve wandered closer as Peggy sat down, though he made sure to maintain a careful distance, and he didn't invite himself to sit down in the second chair. He felt a lot like he was a kid again, being hauled up in front of his teacher's desk for misbehavior - which, as a kid, had generally been for getting into some kind of fistfight with a fellow classmate during his lunch break. This was a different matter entirely, of course, but it still had those familiar shades of being in trouble. It made Steve square his shoulders, bracing himself for whatever Peggy was going to start with.
He startled a little, once she actually voiced her initial concern. The unexpectedness of it was enough to bring his gaze up from his shoes, so he was looking her right in the eye. He could feel his face heating up, memories of last night flashing through his mind.
"I... no," Steve said carefully. "I think that whatever I took... it got worse, as the night went on. Stronger, I mean. I didn't even really register it until Clint, and then - uh..."
He let his words trail off and turned his face from Peggy, embarrassment leaving him flushed and flustered. "I might've gotten a little up close and personal with Stark," he admitted, figuring he owed it to her to tell her the whole truth of the night before, at least as much as he could remember. And, unfortunately, he remembered his time spent in the elevator far too clearly. "But he didn't - he could've run with it, and he didn't." Which, now that Steve thought about it, that was a surprise, if Stark's reputation was to be believed. From the sounds of it, Stark didn't actually have to like you to take you to bed, so really, considering the overtures Steve had been making, it was something of a miracle that Stark hadn't acted on it. Then again, perhaps that was just as much a false rumor as the one concerning Steve taking some anonymous woman to bed and failing to deliver.
