The final episode of season one culminates in the scantily cloaked feelings of Sam and Diane coming to a climax in the pool room of Cheers. When a troubled Diane returns to see Sam one last time before flying to Paris with Sam's shining older brother, her divided heart reveals its innermost feelings for Sam: repugnance.
The final exchange at the end of this episode is priceless, with the at-odds lovers confessing not their devotion, but their disgust with one another for each's quirks and qualms. The genuine confusion over the mutual attraction they feel for one another makes this dialogue hilarious, if not entirely respectful. However, at the last moment physical aggression is deterred, and instead their raging passions meet in a frenized and amorous kiss, changing the terrain of their battlefield from that day forward.
