A clip for the third episode of "Glee" was released. It has already been revealed that the third episode was going to be a tribute for the late Cory Monteith and his character Finn Hudson.

The clip is only a little over thirty seconds long but it's a definite a tear jerker. It begins with a sad rendition of "Make You Feel My Love" as old and new faces silently walk down the empty hallway with small reminders of Finn's absence.

The group walks up to Finn's old locker and places cards, flowers, candles and a football by the locker. Lea Michele's character, Rachel Berry, wasn't seen until the very end of the clip sobbing as she leaned on Mr. Shuester's shoulder.

"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," creator Ryan Murphy said about the episode during a Q&A for "American Horror Story: The Coven" on Oct. 3. "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 struggled even working on it because what you're seeing is what they felt not just about Finn but Cory," he continued.

Small details have been revealed about the tribute episode. At first it was being reported that Finn would be killed off by a drug overdose but Murphy said they decided not to do that and weren't sure if they wanted to disclose how the character died.

It was also revealed that Michele, wouldn't be in the episode until the very end when she sings "an incredibly powerful" song. According to Hollywood Life, the tribute song has been revealed as "Seasons of Love" from the Broadway show "Rent."

"The [episode] is more of a celebration of Cory's life, and the difference he made to us and the fans of the show," a source told the website. "As much as it will be [part of the 'Glee' season] it also feels like a stand-alone episode."

Several original cast members will be coming back for the tribute episode including Amber Riley (Mercedes), Harry Shum Jr. (Mike Chang), Mark Salling (Puck) and Jaayma Mays (Emma). Viewers will also see Dot-Marie Jones (Coach Bieste), Kurt's father Mike O'Malley (Burt Hummel) and Finn's mother Romy Rosemont (Carole Hudson-Hummel).
