Perhaps it was a disease or some unknown force from the Nsgods that had made the people descend into madness. Robb considered himself grateful for yet turning into one of them, and yet he couldn't figure out the root cause. It was disturbing seeing his own friends turn this way. He had never toyed with the thought of turning his blade against the people he thought could trust, but he had to continue reminding himself it wasn't their true nature.

And in the midst of another battle, after wiping his blade clean, he realized he didn't know where Margaery was. She had mentioned to him that she had hiding spots, but was unclear where exactly they were.

And so he began his search for her, trying to stay subtle and quiet, but also hoping to find her.
