"The hardest word to say is 'goodbye.'"

A simple phrase for Glee's new poster, but it speaks volumes about what's to come. Co-creator and executive producer Ryan Murphy tweeted out the new image, which features a black-and-white photo of Glee's late star Cory Monteith, on Thursday. The art promotes the third episode of the season, airing Oct. 10 at 9/8c, which will be a tribute to Monteith, who died from a toxic mixture of heroin and alcohol on July 13.

The fifth season kicks off with two "celebratory" Beatles-themed episodes, which were reworked following Monteith's death. The third episode will then pay homage to Monteith, and in turn his character Finn Hudson, who will also die.
