If Flora's behavior was a little crass she might've avoided her until now and hung out with Hestia mainly during their school days at the behest of her controlling parents but if they were attached at the hip hello to history! ALSO. We can always get into Astoria's blood curse and how Flora's losing her sister would remind Daphne of the precious time she should be spending with hers, but then Daphne would have to ~feel stuff~ and she's not about that life whatsoever. Emotions are confusing things that's she's avoided for a long time, or seemingly so.
Please! Be her serpent. Would you like a custom, so we can talk details here and there?
