In the episode, called "Chuck vs. the Cougars," Richie plays Heather Chandler, a high school nemesis who bullied Yvonne Strahovski's character, Sarah.
"She has a great fight scene," a source told PEOPLE in July. But everything was friendly when the cameras stopped rolling, as Richie and Strahovski were "giving each other high-fives," the source said. "She was friendly. Everybody loved her." – Brian Orloff and Lisa Ingrassia
