That's the wonderful thing about a faerie's natural charisma; even in the awkward adjustment back to socializing after captivity, Ilde's more or less carried through by the fact she can't quite help but be, as it were, 'socially ept'. It helps.

Case in point: "Fairy godmother?" she guesses, friendly enough for being a quieter than she was at the last party in Baedal she attended. Her own costume is fairly clearly evocative to anyone familiar with Disney after 1950, which might account for the direction of her guess - that and the idea of other people dressing up as fairies entertains her, quietly.
