“Glee” has started filming its next season of the FOX TV show, just a few short weeks after the death of cast member Cory Monteith. The cast and crew are currently on the third episode of the season, the one that will directly address the actor’s passing, from referencing drug use to out-of-character PSAs reflecting on the actor’s life.

“They have been piecing together old footage [of “Glee”] to show the audience that Finn had secretly struggled with addiction,” a source close to the production told Hollyscoop. “The whole episode will be two hours long and will deal with addiction and the death of Finn.”

“It is really an odd vibe on set,” added the source, “Lea has always been the ringleader and now it’s almost like people are afraid to even talk to her. She has kept very quiet and all the rest of the cast are extremely supportive, but at the same time keeping their distance.”

“It’s still a really sad time on set,” the source continued. “It is definitely not the same, but as time passes, I am sure this will change.”
