Speaking of Monteith, footage of the late actor -- who died in July 2013 -- does appear in the first hour of Glee's two-hour finale titled "2009." The episode flashes back to fill in the blanks between what happened on-screen, including the origins of Will (Matthew Morrison) and Sue's (Jane Lynch) rivalry as well as the glee club's mandate to be all-inclusive. While we won't spoil it here, the first hour features scores of callbacks to the pilot, including guest stars and its most beloved song from the series premiere.

Colfer also praised Monteith and, when asked to share a favorite memory of his on-screen step-brother, recalled that the duo often did press tours together and "always had accidental fun together. He was a very special guy," Colfer said to an already emotional packed house. Monteith's Finn Hudson was the show's driving force in its representation of the underdog and inclusion. An explination for how Finn died has never been explained on-screen.
As for the final moments of production, leading lady Michele recalled that after Morrison's final song performance had been completed, the "original members of the glee club" -- Michele, Colfer, McHale, Jenna Ushkowitz (Tina), Chord Overstreet (Sam), Criss and Becca Tobin -- fell into "this big ball sobbing" after producers yelled that it was a series wrap on Glee.
At that point, Michele had George Michael's "Freedom" played on the set to help lighten the moment. But before she the cast could leave, Amber Riley (Mercedes) stopped Michele and led the cast to the auditorium stage where, to hear Criss tell it, everyone sat in a circle for a "beautiful moment" and shared reflection. The auditorium stage, Riley said, was cut up into pieces and distributed to its stars.
As for what the Glee experience meant to them, Colfer broke the emotional silence with a joke: "Puberty!" Added Lynch: "Menopause!"
Glee's series finale airs March 20 on Fox.
