Bruce lets them stay in silence for a while. Just breathing. He waits until he himself has forgotten the sound of screaming children and teammates.

"Counting your heartbeat until it's slowed down can also be helpful." Bruce lets out a soft puff of breath. "Once you have cleared out your head, try clearing it of the counting too. It's okay if you can't make your mind completely blank. It usually takes a lot of practice."

He's quiet again, giving Bucky room to work on it himself. He keeps an ear out for any sound of something approaching them, but otherwise, he focuses on his own breathing, on his own peace. Over the years, he's gotten good at meditating. He feels his own heartbeat slowing to a crawl.

"You can stop whenever you're ready. We're not in a rush, though. Take all the time you need."
