Abby hadn't known that the reassurance was needed, though if she'd known the truth of Molly's childhood and upbringing, she could have better understood why Molly acted as she did. But as it were, Abby didn't question it- Molly did well enough and was never rude or caused any problems, after all. And Abby genuinely liked her- what she knew of her, at least.
They were more alike than either of them might have realized, and Abby looked over as Molly sniffed. She opened her mouth to apologize, then closed it again, sighing softly. "You're right. We'll see what we can do. We just need to get back, first."
