Steve was able to dismiss his thoughts with merely a troubled conscience, at least up until the moment that Bucky's attention had focused in on him with a laser like precision. His name was all he needed to know that not only was Bucky aware of what had slipped through his mind, but that there was something to it.

Steve's expression closed off as he nodded mechanically to Bucky's confession about lack of sleep and Peggy's assessment that he was an idiot.

"She's right," Steve said, though there wasn't much of his usual humor in it. He turned towards Peggy, his eyes moving over her expression briefly before nodding again. "Sure."

Normally, especially in this cold weather, he would've volunteered to go downstairs and start the car in her stead, but right now he wanted a moment alone with his best friend.
