Daphne and Roz are sending back the wedding presents (despite the efforts of Simon to keep them for himself) when there's a knock on the door. It's a deliveryman. On behalf of Donny, he's brought flowers for Daphne - and a lawsuit. Donny is suing Daphne for leaving him at the altar!

Meanwhile Mel has revenge on her mind as well...

This comes as a great turn off for Daphne, who thinks Niles is taking Mel's side on the whole thing. Frasier, now threatened to be sued by Donny for revealing to Daphne how Niles felt about her, decides he's done too much harm to the story and no longer wants anything to do with it. But Frasier Crane is Frasier Crane, and he can't help himself. With some help of Martin, he convinces Daphne to go out with him while Martin takes Niles out.
