Cory Monteith's memorial episode on Glee season 5 will be emotional from start to finish, according to new reports.

Insiders who have read the episode's script told E!Online in a Friday report that it is very emotional.

One insider said, "You will cry from beginning to end," while another said, "I cried as I read it, on every page."

Jane Lynch, who plays Sue Sylvester on the show, tweeted Wednesday that the episode, which pays tribute to both Monteith and his character Finn, is "the most beautiful thing."

The episode will begin with the show's various characters learning about Finn's death, according to the E!Online report. Most of the episode will take place in Lima, Ohio, where Finn and his fellow classmates grew up. The characters will grieve Finn's death while also remembering him and celebrating his life.

Rachel, whose relationship with Finn has been at the core of Glee since season 1, will only be featured in the episode's final act. Her scenes in the episode will allegedly be very powerful, and she will be singing. Santana (Naya Rivera) will be an integral part of the episode as well.

The final song of the episode will also be so powerful that the report claims viewers will "ugly cry."

The episode will be the third in Glee's fifth season and will air on Thursday, Oct. 10 at 9 p.m. on Fox. Series co-creator Ryan Murphy said that production would take a break after filming this episode to regroup and properly move on from Monteith's untimely death.
