Cheers – Season 3

Sam falls off the wagon and Diane has a nervous breakdown after the breakup. But after she’s cured, Diane returns to Cheers to recommend her psychiatrist – Dr. Frasier Crane – to help Sam. But she doesn’t say that she’s involved with him. Diane tells Sam that she’s seeing Frasier. Then, they both confess that they no longer have feelings for each other, even though both suspect the other is lying. And since the feelings are supposedly gone, Diane takes her job back.
