Sharpening your skills, Bruce could understand. After all, if he wasn't on the run, he was buried in some kind of book barely anybody could understand. He arched an eyebrow as he watched Clint set up the computer, but he didn't say anything to it. He had walked in late, so Tony could have shown him, but Bruce knew that he'd probably be making a few changes on his private things, at least. Trust had nothing to do with it, either; he'd just rather certain things stay with him.
Which, really, probably meant that Tony already knew. Bruce tried to ignore that thought. And it got really easy to ignore that thought once Clint told him not to move. He didn't tense until he saw the arrow pointed directly at him and it took everything he had not to lose control right then. With a damned arrow coming at him and-- god.
Bruce turned around to face the target and shut his eyes. Breathe in, breathe out. When he felt more in control (faster than he had before -- he needed to log that), he turned back to Clint.
"Didn't anyone tell you that it's a very, very bad idea to point something at me? Don't get me wrong, you're a good... Okay, so you're almost a perfect shot, but things could have..." Bruce dragged a hand through his hair and stared back at the target behind him.
