The "Glee" cast took to Twitter to pay tribute to their late co-star Cory Monteith.
Many of the "Glee" cast members tweeted before the episode aired, discussing "The Quarterback" episode and how emotional the journey was for them.
The cast also recorded a PSA about addiction.
Dearest Gleeks, saying goodbye is terribly difficult- we at #glee have had our time. Tonight's ep is not just for Cory, but for all of you.
