Joan knows that Ted's marriage fell apart primarily because there was a lack of communication of needs and a pressure to make everything seem rosy when it wasn't. She can tell he's trying to make sure that doesn't happen again, and she admires him for it.

She smiles as he touches her hair, and returns the affection by caressing his cheek. "You know a lot already," she says. "Even some of my deep dark secrets." She brushes some of his hair back from his face. "I want to know everything about you too. Anything you're comfortable sharing. Or even if you're not comfortable but want to share anyway. You're always safe with me."
