The Five Week Itch - S1.E6

After Allison's attempt at a cultural date bores Eamon to death, Nicholas reasserts his belief that Eamon is nothing more than her rebound guy. Allison furiously tries to prove her father wrong, but when she follows Puff's advice and plans a romantic evening with Eamon that he tries to back out of, Allison starts to wonder if Nicholas is right. Realizing he's hurt Allison's feelings, Eamon, meanwhile, seeks advice from Finn on how to make it up to her. After Nicholas talks about how he wishes Allison would get back together with Howard, Effie accidentally slips up that it was she who led Allison to jilt her ex-fiancé -- which, of course, infuriates Nicholas. Since Effie is equally infuriated by the way Nicholas treats Eamon, the two end up making a pact where she promises to stop meddling if he promises to stop criticizing Eamon.
