Blaine: I know I've given you so many reasons to mistrust me. But don't you believe that people can change?
Frasier: If I forgive you, will you leave and never return?
Blaine: Yes. I promise you, you'll never see my face in this house again, unless I'm invited.
Frasier: Very well. I grant you this boon, and I forgive you, now get out.
Daphne: Oh, Mr. Sternin, I hope you'll stay for dinner.
Blaine: Sounds like an invitation to me, Fras.
