As much as she wants to explain how it felt to be alone in the moment she realized what was happening, she doesn't think he'll understand, which means that the importance of his being there will be lost on him as well. When she thinks of what could have gone wrong - if it hadn't been just a few minutes, if the symptoms had progressed to affect her breathing, or worse - it doesn't make her feel better. Still, she doesn't want him to feel as if it's his job to watch over her.

"Apparently so."

Able to walk on her own, she feels slightly foolish for what's clearly an overreaction in his eyes. "You don't have to come with me if you have somewhere to be."
