Based on the way Amelia is visibly scheming, Adia has a fairly good idea of what thoughts are going through her friend's head. It's the same expression Caspar had when he first learned about the holiday (never mind that it's not from their culture), and she's relieved that Amelia pulls herself back from the proverbial ledge so Adia doesn't have to talk her down instead.

"I might not be the best person to ask. It's an Earth holiday, and I've only experienced it in the Nexus." And what an experience that was. There'd better not be any cursed candies in the Nexus this year or she's boycotting the holiday, no matter what Caspar has planned. "But from what I've learned, people exchange cards or small gifts. Flowers and chocolate are a popular choice. And usually the couple goes out somewhere for dinner. It doesn't have to be any more elaborate than that."

She looks at the rogue meaningfully. Do not go overboard. "You should ask Harley what she'd like to do and plan your day together. Then it will be the most fun for you both."
