Though Grace smiles, she wishes he'd say more than that. It isn't as if she doesn't understand, though. It isn't easy still, opening up to him like she wishes she could, and she doesn't know how to tell him just how she feels without worrying she's somehow wrong about all of this, as if he hasn't shown time and again how much he cares for her. Every time she says something like that, though, she feels too sentimental to go on, unable to help wondering if maybe it's too much. Instead of saying more, she kisses him, her happiness genuine in spite of her uncertainty.
