Would not blame her in the slightest if she opted out to spend time with her family. But they might be of the opinion that, if her DD wants to celebrate Halloween as most kids do, she goes out to trick and treat with her friends and father. That might be part of the healing process. I doubt whether she would do it, as they are a very private family, but seeing as Strictly directly coincides with halloween this year, her daughter could have fun in the audience.
Fair play to whatever they decide, it was your worst nightmare, and Claudia was amazing going back as quickly as she did.
