Dick put his arms around Carrie. It hadn't been hard for him to find her. She liked to find high places to think, and right now she had quite a lot to think about. Unlike Carrie, he was in uniform; there was a slight bulge around his chest where he was bandaged from the fight with the Joker. And also unlike Carrie, there were no tears in his eyes.
Carrie was shaking with sadness and anger. He knew her well enough to recognize it. Dick was mostly feeling disappointment. It hadn't been unexpected. This was the kind of thing that Bruce did when things got complicated. When forced to feel more difficult emotions. He ran. Retreated, in fact; pulled so far into himself under the guise of the Mission that he could almost pretend he wasn't in pain. It had happened before and it would happen again, but Dick had been holding out hope that it wouldn't, this time.
He continued to hold Carrie, resting his head on her shoulder, until she was ready to speak. If she never was, that was fine; he could hold her all night and into the morning. As long as she would need him, he was going to be there.
