Astoria wasn't quite sure what to make of Daphne and Dean breaking up. On one hand, it would bring a certain level of peace to the family again. It would mean Alcide was placated, even if Daphne hadn't broken up with Dean for those reasons - and she wasn't even sure if Daphne would tell Alcide. On the other hand, she knew Daphne had cared about Dean and - of course - she didn't want her sister to be hurting. Still, perhaps it was for the best. A bit of hurt in the short term would likely lead to happiness in the long run.
Daphne could start to heal from the incident at the WWN and then find Mr. Right. In the meantime, Astoria could keep her sister quite busy with wedding planning. Astoria knew there was certainly a lot to do.
When she popped into Diagon and made her way down to Baxter Bakery, she was rather surprised to see the sight of her sister - blond - sitting at the window table as she approached. It felt... right, seeing Daphne blond. It was a rather idiotic thing to smile about, but it made Astoria grin. She went right in and to the table, not caring too much about getting a drink off the bat. "Hello."
