Zelda arrived with her dad, because it's an Edgar de Leon party and because she recently learned that her father is going on a date with Blythe and she's very curious about who this guy is. She's also so happy she has an excuse to wear a cute but seasonally-inappropriate dress because so rarely is her vacation wardrobe ever actually practical. But, for once, it's almost practical. A win!

She's cheerful and plans to have a good time because she is not trying to think about impending doom and will almost certainly embarrass herself after she gets drunk to try and win herself a tiara.
