The New Directions battles the "Throat Explosion" at the National High School Show Choir Championship in Los Angeles. This is the choir's last hoorah, as Glee Season 5 transitions to New York City episodes through the rest of the season.

In Glee Season 5 x 11, guest stars Amber Riley (Mercedes), Mike O'Malley (Burt Hummel) and Carole Hudson (Romy Rosemont) will be supporting the New Directions. Burt and Carole are expected to be emotional to watch the choir without their dear son Finn (Cory Monteith).

It seems Glee Season 5 will soon say goodbye to Marley (Melissa Benoist), Ryder (Blake Jenner), Jake (Jacob Artist), Unique (Alex Newell) and Kitty (Becca Tobin). Sue Sylvester (Jane Lynch), meanwhile, moves to New York!

"Unofficial word on the street is the show will leap ahead several months between the graduation episode and Sam, Blaine and Artie's arrival in the Big Apple," reports TVLine.
