Pete deals with the fallout from taking a movie starlet to bone-town, which involves the conspicuously-introduced Dot to cool to him... but not so much that they don't still get married before this episode is over. And if you feel like that's a spoiler, it's only because you don't understand how little importance this event seems to hold for anyone involved, including the writer.
Far more important seems to be Pete getting his own unit with Landy (who is up to something shady), a labor union forming in Hollywood, and some incremental development of a rabbit character at the studio.
