Ami started to leave - she wasn't going to have a better chance - but something made her look back after only a few steps.

He was hurt. Bleeding. Injured. Because he had protected her. And he hadn't done it to keep her trapped; he was still saying to go home. She couldn't be so ungrateful and just leave him. She found herself walking back towards him, almost without thinking about it.

There wasn't much she could do here... but. "Come on. Lean on me until we get back to the castle."

He probably couldn't rest much of his weight on her, but at least it might hold him steady.
