Get your tissues ready. The most anticipated and emotional episode of ‘Glee’ will air on Oct. 10, and the new 30-second trailer has every character sobbing while they pay tribute to the late Cory Monteith.

In the promo for Glee‘s tribute episode, “The Quarterback,” the halls of McKinley High are silent and deserted. During an emotional rendition of “Make You Feel My Love,” we see both old and new faces remembering their classmate, Finn Hudson, while they also remember their true friend, Cory Monteith.

‘Glee’ Tribute To Cory Monteith

After seeing the new promo and composing ourselves, we know that next week’s tribute will be a beautiful way to remember Cory.

We see the current students at McKinley gathered around Finn’s old locker, setting down flowers, “We’ll miss you” cards, candles, and a football. Many alumni of the school also return, including Kurt (Chris Colfer) who is crying and wearing to his brother Finn’s varsity jacket, and Rachel (Lea Michele), who has never looked more heartbroken.

We know that she won’t appear until the end of the episode, and it’s going to be an extremely tough scene to watch. At the very end of the promo, we see her bawling on the shoulder of Mr. Schuester (Matthew Morrison).

The episode couldn’t have been easy to film, or to record the songs for. Reportedly, the cast will sing “Seasons of Love” for Cory, as well as the following songs: “I’ll Stand By You,” “Fire and Rain,” “If I Die Young,” and “No Surrender.”

Ryan Murphy On Cory Monteith Tribute: The Crew Was Sobbing

“He was the most kind, the most generous — never a bad word for anybody,” Glee creator, Ryan Murphy said at a Q&A for American Horror Story: The Coven on Oct. 3.

That is probably why alumni of the show, who were no longer regulars had reached out to Ryan after Cory’s sudden death on July 14. However, although the whole Glee family was there, the emotions on set were understandably running really high — and it all came through in the episode.

“What you will see in the episode is what really happened,” Ryan said. “Brad [Falchuk] and Ian [Brennan] and I wrote that episode and Brad directed it, and those performances that you’ll see, almost everything in that episode is from the first take of every performance because the actors and the crew had a really hard time shooting it.”

He continued, adding that even the crew was having an extremely difficult time:

It was very rough, and it was very rough with Lea. I’m very proud of it. I think the performances are quite stunning. It was tricky. You had to have a hard eye when you were putting it together. People still are not over it and it’s still very difficult. I’ve never seen a crew that you can’t continue shooting because they’ve left the room sobbing. It was very hard. I struggled even working on it because what you’re seeing is what they felt not just about Finn but Cory. It’s amazing performances across the board and everybody went into it with a lot of love. What I loved about it is when you write something like that, there’s no right way to do it.
