Bruce shakes his head. "You didn't see what he did," he says quietly. "He funded Crane nearly destroying the city, and invaded with an army. Gotham was evacuated, it looked like an atom bomb had gone off, it was so bad. Ivy helped me and she died for it. He revealed Barbara, dragged her out of the Clocktower and gave her to Crane."

He lets out a shuddering breath. All that and more. He thought ... he thought something had reached Jason, when he left the fight and when he came back to watch over Bruce. He saw the red bat on his chest. He had Bruce's life - all of their lives - in his hands and he'd chosen to act to save them. Jason either hasn't been through that yet, or he's discarded it. What is Bruce supposed to do against that? He can't force him. He can't shake Jason and tell him to stop acting like a stupid child, that he's smarter than this and it's deplorable, that it's embarrassing to see him trying to interrogate him like that.

Bruce can believe Jason truly wants to know if there's a chance the Joker is present. He can't believe he cares.
