If you somehow didn't guess already, you will need Kleenex for tonight's tribute to Cory Monteith on "Glee."
A new trailer offers plenty of fair warning, as it features Monteith's girlfriend and co-star, Lea Michele, singing "Make You Feel My Love" as the rest of the cast mournfully bids farewell to Monteith's character, Finn Hudson.
It's only 30 seconds long, but good luck making it to the end without chocking up.
On Oct. 2, the British Columbia Coroners Service confirmed that Monteith's July death in a Vancouver hotel room was accidental.
He "died of mixed drug toxicity, involving intravenous heroin use combined with the ingestion of alcohol," the coroners service said in a statement.
With Thursday's episode of "Glee," the cast and the show's fans will try to say goodbye to both Monteith and his lovable jock character.
"It was incredibly difficult to work on. It was very difficult to shoot," "Glee's" co-creator, Ryan Murphy, told E!. "I mean, the interesting thing about that show is that those actors and the creators really, really loved Cory."
The episode is called 'The Quarterback,' and you know Cory really was that, to that group of people and to me particularly.
There was nobody on that crew that did not like Cory.
"The "Farewell to Finn" episode will air on FOX31 Denver at 8 p.m.
