Astoria showing up was maybe even a bigger surprise than the surprise party! Daphne was happy to see her, and glad that she felt up to leaving the house. She paraded Astoria around the room to introduce her to everybody (probably as "my baby sister Astoria").
She was confused when Astoria's clothes spilled out of her bag. But once she understood that Astoria was staying with her she got excited, because Daphne loves having visitors.
