Aire/Yunita - Forgiveness
Aire understands that Yunita's heart is frail - brought down and hammered on by people who don't care. She still hasn't forgiven Brandt and especially Jusqua for the pain that they've caused her because of their ignorance.
She just hopes that Yunita's forgiven her for abandoning her from the beginning.
Brandt -> Yunita -> Krinjh - Longing
She really doesn't mean anything when she says to him, "Maybe Krinjh and I should go on ahead," but it strikes deep into Brandt's heart, that she'd leave him behind for (what? a stranger? who is Krinjh, anyways?) some person they've met in the desert.
And you know what? When they find out that Krinjh is actually a ghost? When they find out he has an elven lover?
Brandt - Age
Brandt wonders if they know that he's still only fourteen, barely an adult, he's not even had his coming-of-age ceremony yet.
And Jusqua. Jusqua's only half a year older than him and Yunita thinks he's older than her.
It's funny, really. Aire's probably the youngest out of all of them.
Brandt/Jusqua - Separation
Lying in bed in Liberte, Jusqua finds himself thinking about Brandt and wondering what he might be doing on the other side of the world.
It's unsettling, how much he finds himself wondering. If they're staring up at the same sky when it's nighttime, if he's had any near scrapes with monsters like he's had. If Brandt's acted on that crush he's had on Yunita back when they were children.
It's not the first thing he asks when they meet each other again, but it's close.
Turns out, he doesn't like her anymore. He's had some time to think, and Brandt decides that Jusqua is just right for him.
