Daphne was beyond annoyed and his ridiculousness. Couldn't he see that he was making a mountain out of a molehill? If he didn't trust her judgment with his son, then he shouldn't be leaving him with her in the first place.
This whole thing reminded her quite a bit of their last fight at the Three Broomsticks, but she didn't imagine that he would be showing up with flowers, jewelry, and an apology this time.
She just grunted at him in response before she turned and headed off to kiss her sleeping son goodnight and then get some shut eye. No matter what Miles thought, she deserved a good night's rest.
