Rosie Sparrow is the sister of Becky Sparrow. The two were foreign exchange students, and were at John Adams High on a 6 month student visa. She and her sister went on a double date with Shawn Hunter and Cory Matthews, the latter being her date. Although she and Cory were paired together, Cory avoided Rosie's attempts to kiss him, and instead told her the story of his girlfriend Topanga Lawrence's depature to Philadelphia. Rosie told Cory that his story was "beautiful" and "heartfelt", and the two cried together. Later, Shawn told Cory that the Sparrow sisters wanted to see him and Cory again.
