I'm surprised the story even took the time to depict Armia's mental distress over having been betrayed and abandoned by the people she looked up to. It was at least there for this chapter instead of her being magically and instantly fine like nothing happened. Still quickly resolved, mind you, but better than nothing.
She looks like a young and naive girl who wasn't as bad as the other two were. She was just timid and too weak-willed to stand up to the bullying that Raust was taking. Quite believable if she's still a teen and the youngest in the party.
I'm also surprised Raust accepted the apology money. Given the doormat nice guy stereotypes, the usual thing would have been for him to refuse the money and say everything is fine. I guess it could be a token of kindness as well since if he refused, it might be mistaken as a sign of non-forgiveness and that he doesn't want anything to do with her.
