Glee fans are likely to get choked up over a new promotional photo for the upcoming season, which premieres Thursday.
“The hardest word to say is ‘goodbye,’ ” says the caption alongside a close-up black and white picture of Cory Monteith.
Audiences are still getting used to the idea of Monteith’s absence, as is the Glee cast, Jane Lynch told PEOPLE recently.
“I think that grieving comes in waves,” she said. Lynch added that her heart goes out to Monteith’s girlfriend and costar, Lea Michele.
“I know it’s just been brutal for her,” she said. “I never lost a boyfriend when I was 26 years old.”
Catch the Glee premiere – “Love Love Love” – at 9 p.m. ET on FOX.
