Ahhh, that's definitely not cute! [HE DOESN'T WANT TO BE A NANNY. Waving his hand in dismissal! And also standing up from the table at the same time, because he can't really manage to stomach anything either when he's this nervous (try as he might to pretend otherwise). He should start looking.]

I won't let you down, 'kay? And I trust you too, so you better not let me down, either! [He'll still worry anyway, of course. It's what he does, even if he does it like an inept moron.]
