That right there is the cornerstone of the problem. You assume he is doing it to show off. It's very likely that he was surrounded by that kind of language from birth and it doesn't even occur to him that other people would not know what that means.
Sera jumps to the same conclusion you did: he is being a snob.
But he's not. He's just talking naturally. I can really relate to Dorian on this.
Nope, i don't assume he's doing it to show off since i know he learned to speak that way, so is Sera not using words she doesn't understand. Poeple are different. The thing is, Dorian can speak plainly. He knows, they talk a lot. Sera can't use big words because she didn't grew up that way. And yes, she could learn some but imo, i don't see why she should if people already understand her... if it happened that way, i'm sure she'd learn some.
Dorian and Sera get along well together so i'll bet she learned some from him since he also explains the meaning of the words he uses (bless him tbh
). Wish there was banter that showed this.
wow calm down ppl, this thread moves so fast.
