Lilith: Frederick, have a seat, we need to talk to you.
Frederick: What about?
Lilith: We know that you've been trying to maneuver us together and it's only natural for a child of divorce to want that. Generally speaking, your plan would be fruitless, but when your father and I let down our guard and looked at each other in the candlelight, we realized that we belong together. In other words, we're getting remarried.
Frederick: Do you really mean it? [Frasier nods] This is going to be the best Christmas ever! I'm gonna go tell Uncle Niles.
