Steve was surprised when he heard James' voice, his hands twitching as he caught himself from throwing them up in a defensive position. He'd been lost in his own head, thinking so hard on not thinking about anything, that he hadn't been paying attention to his surroundings.
"Oh...nothing." he answered with a shrug. "Computer simulation thing." He couldn't decide if it were better or worse that it was James. He knew some, but not enough. If it had been Bruce or Thor or even the raccoon he could have talked about it. Maybe. Or if it had been anyone else he could have ignored it. James was a sort of middle ground he still wasn't sure how to navigate.
