Carly visits Shelby and apologizes, and the fight is back on. However, Nevel Papperman alters a clip of the press conference to make it look like Carly intentionally tackled Shelby's grandma to dupe Shelby into fighting Carly. Shelby, furious, attacks Carly for real during the match, Carly then clinges onto Shelby's leg for the rest of the "fight". Nevel's plot is revealed and as punishment, he is beaten up. The show concludes with Shelby appearing on iCarly. Meanwhile, Spencer suffers from ridiculous side effects while taking an experimental allergy medication.
