The never-ending tirades of Sue Sylvester (Jane Lynch) against Will Schuester (Matthew Morrison) continue in the upcoming episode of "Glee."  

In season 6 episode 9, Sue's main goal is to make sure to give Will a hard time as he returns to McKinley High's glee club after his extremely challenging stint as Vocal Adrenaline's choir coach. The ruthless high school principal tells Will, "I do not retreat, I reload," in the promo trailer for the episode. The promo ends with Sue physically attacking Will in the choir room. 

Meanwhile, the rest of the New Directions have their hands tied in helping one talented young kid celebrate his upcoming bar mitzvah after being pressured to present a phenomenal boy band by the other kids in school. The official synopsis for the episode titled "Child Star" that was released by Fox reads: 

"A high-strung, demanding tween requests that the members of New Directions perform at his bar mitzvah, and the glee club must band together for its first public performance. Meanwhile, Spencer pushes Roderick to lose weight." 

"Glee" season 6 episode 9 airs on Friday, Feb. 27. It will feature the songs "Uptown Funk" by Bruno Mars and Ariana Grande's "Break Free." 

On the other hand, the cast and crew of the hit teen musical comedy wrapped up filming the entire final season last week. The cast bade their own heartbreaking farewell for the show after working on it for the last six years. 

Lea Michele, after portraying the role of New Directions diva Rachel Berry, posted her emotional farewell to the show in a series of Twitter posts. She uploaded the photos of the entire cast as they performed in the McKinley High Auditorium for the last time, as well as several pictures of her with the people that she had worked with in the past, including Darren Criss, Chord Overstreet, and Mark Salling. 

But perhaps the most heartwarming photo that Michele posted is the image of her holding the framed football jersey of Finn Hudson, portrayed by her late boyfriend Cory Monteith. The actress seems to be taking the memorabilia with her as a remembrance from the show.
