The Glee club is heading to Nationals in L.A. Jenna and Kevin have so many memories of shooting this episode and were emotional after re-watching it. They talk about how they felt shooting the Finn tribute, their reaction to Burt and Carole's return, the many guest stars, Amber Riley bringing her Mirrorball Trophy to the set, why filming on the double-decker sightseeing bus was a nightmare, and a touching story about why their performance of "America" was so personal and relevant to Kevin.
