He let her die? What could he have done? What could anyone have done that they didn't try, and keep trying? She wants to argue, or defend Batman, or at least just ask that question, but when she opens her mouth to speak all that comes out is a strangled sob.

She hesitates only a moment, but the offered hug is a very clear message. He isn't angry, or disgusted, or even disappointed in her. All of the emotion she's been pushing down for weeks comes surging to the forefront. Her shredded confidence, the guilt, the injustice of it all, the desperate fear that she could never be forgiven, all so carefully tucked underneath the fear and anger leftover from being so thoroughly physically beaten-- all of it rises to the surface in that one simple moment.

Another sob escapes her before she turns to press her face into his shoulder. She clings to him like a life-preserver as she starts to sob in earnest, loud and unrestrained. She even carefully keeps her chin tucked so that his shirt might at least be saved some of the soaking her face is getting.
