You're having an anxiety attack. It doesn't help that you're on patrol with Bruce. You've heard he doesn't take well to emotional outburst while on patrol well.
What you'd heard was oddly, no comfortingly enough not exactly true. Bruce isn't good at comfort and he understands that his way of handling things in the past was less than ideal.. he wants to do better that's why he's trying out some new techniques with you. New apprentice new him? Right?
"What's wrong..? Do you need space? What do you need to tell me and I will help you." Bruce stops what he was doing and hugs you while rubbing your back. He isn't sure if this is how to help he isn't good at this, he does know some things like sometimes you need silent reassurance through touch, or assurance through words and no touch, or words and touch at the same time. He knows everyone is different so he should be gentle cautious.
Bruce trying his best sadly his best is not what anyone wants from a man as calculated as him.. his reactions seem forced even if he's genuinely worried. He truly cares about you and everyone else he only wants the best for you all.
