"Well, of course this is London, Master Inigo," Ceinwen patted his head. "I know when I'm speaking English. Besides, if we were in France we'd all be wearing funny hats and we would be calling our wands 'bread.' I may not know much but I lived in France for five years." She squinted at the school building and took advantage of the moment of clarity she was feeling. "A day school for... oh. Oh I am sorry to hear about that, dears. I lost my husband and my brother in the first Wizarding War, and I did what I could to protect my hometown in the second one. Of course," she glanced at Inigo again, "when i said the Second War a moment ago, I was referring to the Muggle one, not the wizarding one. Hmm." She pondered for a moment.
