Hannibal didn't need more than the first threat of tears to be up from the table again and at her side. He knew that there was frustration right now for River, and it was the least of the emotions running through her. He also knew that at times he could be too clinical, too rational, for the way River worked. Her mind stopped at the logic of the way her world had been, she could not see that chaos was its own logic here.
It was not a fault. But it would forever cause her pain.
He didn't try to shush her or quiet her crying. She needed to get it out. The faster she worked through everything she was feeling, the faster she would be able to move to the next step.
Hannibal stood at her shoulder, smoothing down her hair. He could not speed her recovery, or force her to concede any of her emotion, he could only be there for her, and he would be.
