Glee said goodbye to McKinley High with a special two-part celebration of their 100th episode milestone. Original cast members returned for a bittersweet reunion to relive their fond memories of the New Directions show choir by revisiting and remixing  their most popular performances (as voted upon by fans of the show).

After giving it their all with a fine rendition of U2’s “I Still Haven’t Found What I’m Looking For” at their very last Nationals competition in LA, graduating seniors Blaine (Darren Criss), Sam (Chord Overstreet), Artie (Kevin McHale), and Tina (Jenna Ushkowitz) came together for one last time to sing a stripped down version of a New Directions’ original, “Loser Like Me“. Many beloved trios and duos were restored, including a triple diva-off between Rachel (Lea Michele), Kurt (Chris Colfer), and Mercedes (Amber Riley) on the signature song from Wicked, “Defying Gravity“. Kurt and Mercedes also belted out an incredible powerhouse duet of “I Am Changing” from Dreamgirls. Quinn (Dianna Agron), Santana (Naya Rivera), and Brittany (Heather Morris), as known as the Unholy Trinity, reformed for a scorching hot performance of Britney Spears’ “Toxic“.  Relationships, both of the friendly and romantic kinds, were rekindled within the halls of their former high school. The star vs. star rivalry between Rachel and Santana was resolved with a duet of Oh Honey’s “Be Okay“. Brittany and Santana found their way back to each other after singing and dancing together to the tune of the vivacious “Valerie“. Puck (Mark Salling) wooed Quinn over by dedicating a performance of “Keep Holding On” to his long-time love, and after several years of wondering “When the heck are these two ever going to get together?”, Puck and Quinn are officially on, and to top it off, they finally sang a song together. Their perfectly suited duet of Pink and Nate Ruess’ “Just Give Me A Reason” just so happened to be the last performance to be given in the choir room, marking this moment as not only end game, but the end of a era as well.

New Directions came full circle with a final encore of the song that started it all, “Don’t Stop Believin’“. The originals and the newbies delivered this performance in honour of Will Schuester (Matthew Morrison), the teacher who restarted the Glee Club and thus inspired every member to believe in themselves and go after their musical dreams.

In the next episode, the show will shift to New York full-time, with Blaine, Sam, and Artie joining Rachel and Kurt in the Big Apple. Other characters from the original cast are expected to make guest appearances every now and then. This may be the end of the New Directions chapter, but there are still many stories to be told and songs to be sung about this talented group of stars in the making.
