When Jesse's car is stolen she goes looking for a new used car. Linda's mechanic gets her a good deal on an '84 Volvo so she takes it but while out driving it with Diego she notices her old car in an alley. She reports that she found it and when she shows a uniformed officer its location it isn't there anymore. While out driving again though they notice it again at a different location but it gets destroyed.
Diego gets passed up for a teaching position so Irma takes him to Niagara Falls to cheer him up but scares him off. She tells him she's going to change into something more comfortable but comes out in a wedding dress and proposes to him. That leads Diego to go back to Buffalo and apologize to Jesse for having proposed to her when he came back to Buffalo from California. He now knows how it feels to get asked out of the blue to marry someone. Jesse and Diego get back together but hold off on getting married. Kurt slips a disk in his spine while trying to lift a heavy box at work. At the hospital Jesse gets asked out by the attending doctor but passes on his offer when Diego shows up and wants to get back together. Dr. Danny feels uncomfortable around the attending doctor.
Jesse tells Diego she can't marry him. Then we go forward four months and Jesse gets a job as a nurse's aid but quits when she can't handle it. She does however get it back later. Diego returns having quit his job at UCLA because he got his old job back since funding was given for the art department. He surprises Jesse by popping the question again but she still says no.
