Cheers - Season 11 Episode 17

It was Lilith that walked in on Frasier and Rebecca as they were about to make love for the first time. All three are shocked at their situation and Lilith, the most confused, runs off to Cheers to get some answers from Sam as to what's been going on with her husband. Sam and the gang at the bar are as equally shocked by Lilith's news as Lilith was to see it. However it's not quite as simple for Frasier, who refuses to take Lilith back as easily as she wants. There is still the issue of the Dear John letter she wrote him. Apparently the letter was written by Dr. Pascal in an attempt to solidify his relationship with Lilith. Dr. Pascal thinks that he will have some say in what happens between himself and Lilith and between Frasier and Lilith. And as the fourth party, Rebecca will also have a say in what happens between herself and Frasier and between Lilith and Frasier.
