Emily Waltham (Helen Baxendale): The English niece of Rachel's boss Mr. Waltham, who arrives for a two-week visit to New York in "The One with Joey's Dirty Day". She has a whirlwind romance with Ross and they decide to get married. Her friendly relationship with Rachel soon changes during the wedding. The friends fly to London for their wedding in "The One with Ross's Wedding" (airdate May 7, 1998; Season 4, No. 23 & 24), and Ross accidentally says Rachel's name at the altar, humiliating Emily in front of her friends and family. She aims to reconcile with him at the airport in "The One After Ross Says Rachel" (airdate September 24, 1998; Season 5, No. 1) but sees Rachel with him about to go on their honeymoon and storms out again. Ross tries to convince her to move to New York. She agrees but makes him promise to get rid of everything Rachel has ever come into physical contact with, in the friends' apartments, which would be virtually impossible, and she demands that he never see Rachel again. When she learns that he's having dinner with the old gang—including Rachel—she tells him she cannot trust him and she decides to end the marriage. She makes a final voice cameo in "The One with the Ride Along", when she leaves a message on Ross's answering machine the night before her new wedding, telling him she is having second thoughts about it and is worried that they made a mistake splitting up. Rachel accidentally deletes the message, but tells Ross about it and convinces him not to respond to it. Emily's surname is that of the city where both creators of the show attended college.
