In the fourth season premiere, Ross and Rachel briefly reconcile after Ross pretends to read a long letter that Rachel wrote for him, but continues to insist that the two were on a break so they break up again. Joey dates Kathy (Paget Brewster) a girl that Chandler has a crush on. Kathy and Chandler later kiss, which causes drama between Chandler and Joey. Joey forgives Chandler only after he spends a day in a box as punishment. Phoebe becomes a surrogate mother for her brother and his wife Alice (Debra Jo Rupp). Monica and Rachel are forced to switch apartments with Joey and Chandler after losing a bet during a quiz game, but manage to switch back by bribing them with Knicks season tickets and a one-minute kiss (off-screen) between the girls. Ross begins dating an English woman named Emily (Helen Baxendale), and the season finale features their wedding in London. Chandler and Monica sleep together, and Rachel decides to attend Ross and Emily's wedding. While saying his vows, Ross uses the wrong name at the altar (Rachel's), to the shock of his bride and the guests.
