Originally, Claude somehow started to miss Athy. Athy visited the castle because she thought that Claude was in the parade. Well, he's not. Athy almost escaped, but Claude said that if Athy uses magic, it'll hurt Claude. I don't remember why, but Athy cried out loud. Then WA-LA some sweet drama stuffs and a hug.
When I read it, it was one of my favorite scenes. Simple yet beautiful. They also talked about Diana. If i'm not mistaken, this is their conversation:
Athy: "I miss Mom.”
Claude: "Me too."
