Glee “On My Way” Preview (Video)

The Warblers perform "Glad You Came" during Regionals

A preview of Tuesday night’s highly-anticipated episode of “Glee” has gone viral and has fans excited.

The video shows Rachel and Kurt being confronted by Dalton Warbler Sebastian, who provides blackmail and demands New Direction pull out of the race to Regionals.

Of course, it wouldn’t be much of an episode if New Direction didn’t show. The group heads to Regionals to find that The Warblers are fierce competition.

The group is seen performing hit song “Glad You Came,” a song made famous by The Wanted while Brittany, Santana and Mercedes are spotlighted on Kelly Clarkson’s ‘Stronger (What Doesn’t Kill You), reports Pop Crush.

You can catch the new episode of “Glee” tonight at 8 p.m. EST on Fox.

Last week was an equally anticipated episode of“Glee,” when one actress took on the late Whitney Houston. For a special Valentine’s Day episode,A mber Riley, who plays Mercedes, performed Houston’s famous “I Will Always Love You.”

In the February 14 episode, Riley decideds to go it alone rather than choose between current boyfriend Shande and ex Sam, according to the Washington Post. She brings tears to the eyes of her classmates as she sings the lyrics of the song.

“I hope life treats you kind, and I hope you have all you’ve dreamed of,” She sings. “And I wish you joy and happiness but above all this, I wish you love.”

In another scene appears on stage in a red dress belting out the most famous lines of the song, “And I will always love you.”

Interestingly enough, the episode was actually completed before Houston’s death Saturday. Following her death, producers for the show reportedly announced they would dedicate the episode to the late star and as the show ended, they made good with on their word and a dedication card was displayed on the screen.
