Who is Vicki from The Sportswriter and what is their importance?

Vicki is the young, divorced nurse that Frank has begun dating. When Frank and Vicki go to Detroit together, Frank wants to show her a good time so that she might consider sharing the rest of her life with him. Their weekend, however, gets off to a rocky start when Vicki catches Frank going through her purse.

After their trip to Detroit, Frank spends Easter with Vicki and her family. Vicki is unhappy to see Frank, and Frank begins to think that Vicki wants to break up with him. Vicki tells Frank that his ex-wife is having an affair with his doctor, a story that is later proven to be a lie. However, Frank's reaction to the story causes Vicki to become more convinced that they are not meant to be together. At dinner, Frank talks sports with Vicki's father and brother. The conversation becomes heated and Vicki's brother ends up leaving the room. This is the final straw for Vicki, who tells Frank they have nothing in common and should not see each other any more.
