what was that flashback? I feel like I'm missing something, maybe I need to re-read the series
The woman crying at the grave? I don't think we know yet, it's probably something that's being set up for further reveal later.
ahh alright, the flashback made me think maybe it was the younger self of the lady and the maid, and they somehow knew each other
You were right, that's a younger Violet a while after the dragon attack, at her grandfather's grave (most likely). Also, Violet said out loud that Dahlia used to work for Graat in chapter 8.
Hinata is the low key MVP, yet again ^_^ It's a cute touch that she choose a star hairpin for Hoshino, to fit her name. Hinata is really good at taking care of people and it shows.
The difference in dynamics between the two couples is really funny, one is like a sad puppy, willingly letting her lady tend to his wounds, while the other is like an angry cat, stubbornly refusing to let her wife help. :D
