Harrison tells her that he needs to go to San Francisco for a business trip: on his way, he stops by at Reed's flowershop and orders two flower bouquets - asking for discretion. Wanting to surprise him and despite Reed's warnings, Julia flies to San Francisco, convinced that Reed was wrong. Julia finds out that he is married and finds him at a local restaurant. Dressed as a waitress, Julia makes a scene at the restaurant, making Pamela suspicious.

Substituting for Paula's absent secretary is one of the firm's receptionists, Liz Curran (Anne Hathaway), who dates mail-room clerk Jason Morris (Topher Grace).
