S3·E2 The Twins, the Trustee, and the Very Big Trip

Kelly bonds with her baby sister, Erin. She bows out of a six-week trip to study in Paris with Donna because she wants to spend time with her family. Brenda and Dylan clash over their new living arrangements. Cindy and Brandon realize that Brenda is unhappy, but she is too stubborn to give in. Jim threatens to freeze Dylan's account unless he helps convince Brenda to accept a trip to Paris. Dylan persuades Brenda to go because he believes it is a great opportunity for her. Jim makes amends with Brenda before she and Donna leave for Paris. Steve and Brandon get dates with visiting identical twins. Steve's date experiences a series of health problems (food poisoning, allergies), so he tries to dump her for her sister. The girls switch places to get revenge on him.
