In case you were wondering the in-universe name for Hawthorn’s condition.
Thorn: What’s going on, chickadee? Why don’t you think you’re a good sister? Did your parents say something like that to you?
Thorn: Did you and Hawthorn have a fight?
Thorn: You’re really in-tune with him. And I know that doesn’t just happen overnight! You paid a lot of attention. Put a lot of time and effort into it. Why is someone who does all that still beating herself up?
Hyacinth: Because I — I don’t always think nice things about him while I’m doing it!
Thorn: . . .
. . . You’re siblings.
Hyacinth: But I’m supposed to be better than that!
Thorn: No, you’re not! Where are you getting this? You’re only human. You’re not required to think only sweet fluffy things 26/7. He’s only human too. So he’s gonna be annoying sometimes. You don’t have to pretend that’s not true just because he’s changeling-spectrum.
Hyacinth: There’s another thing! I’m not sure whether “changeling” is an offensive term. If I was really a good and caring person, it would be obvious!
Thorn: Aha! It all makes sense now.
Thorn: You’re getting this from people on the net, aren’t you.
