Glee‘ is getting ready to wrap its third season with its ‘Goodbye’ episode, and with graduation on the horizon, it looks like there will be plenty of tears shed in the halls of William McKinley High.

With Nationals behind them, New Directions are faced with another obstacle — saying goodbye to their friends. A new preview for the episode shows Rachel, Sue, Quinn and more welling up as they bid farewell to their high school years.

Sue and Quinn share an emotional hug before the former Cheerio locks lips with Puck one last time. Kurt and Blaine make a commitment to each other, and Rachel sobs as she shares a heartbreaking moment with Finn. There are as many kisses as there are tears!

Of course, the show can’t go out without a bang. Gloria Estefan will guest star as Santana’s mother, while the episode set list will include Beyonce‘s ‘I Was Here,’ Madonna‘s ‘I’ll Remember,’ Bruce Springsteen‘s ‘Glory Days’ and Green Day‘s ‘Good Riddance (Time of Your Life),’

Gleeks are going to want to set their DVRs for this one! The season 3 finale of ‘Glee’ will air on Tuesday, May 22 at 9PM EST.
