The gang's all back together for McKinley High's Homecoming! Yes, it's a reunion with the original Glee Club members! Jenna and Kevin have loads of personal memories from shooting this special episode, including the mood on the set with everyone back, how Naya Rivera felt having to perform Ariana Grande's "Problem" (IYKYK), meeting the newbies, the actor that fell flat on his face during their "Take On Me" number and so much more!
