Ready to get taken to a new magical land? ABC found success with its series “Once upon a Time,” and on Thursday will be premiering its spinoff – “Once upon a Time in Wonderland.”

On a slow night for premieres, TV lovers still have a lot on their plates Thursday. “The Vampire Diaries,” “The Big Bang Theory,” “Scandal,” “Elementary,” “Parenthood” and more all have new episodes airing. But the big events of the evening air at 9 p.m.

“Glee” will be airing its tribute episode to deceased cast member Cory Monteith. “The Quarterback” is bound to be a tear-jerker as viewers bid adieu to Monteith and his character Finn Hudson. Former members of New Directions will return to McKinley High School to remember Finn, while Mr. Schue will encourage the gleeks to “memorialize him in the way we do everything – by singing about it.” The highly anticipated song of the evening is Monteith's real-life girlfriend Lea Michele’s rendition of “Make You Feel My Love,” a song by Bob Dylan but covered by Adele.

Also at 9 p.m. is “Grey’s Anatomy’s” 200th episode on ABC. “Puttin’ on the Ritz” will find the doctors of Grey Sloan Memorial throwing a fundraising gala while others working in the hospital face a busy and difficult night.

Check out the episode description for the “Once upon a Time in Wonderland” premiere below and let us know what you’ll be tuning in to watch:

“Once upon a Time in Wonderland” (8 p.m. on ABC)

Viewers will meet Alice, a young woman who returns home after ending up in a “mystical place” called Wonderland. Everyone thought she was dead, and when she starts spouting imaginative stories she’s removed from her home and put into an asylum. About to have a procedure done to “forget her pain,” Alice is rescued by some inhabitants of Wonderland who tell her that her one true love, Cyrus, is still alive. But it won’t be an easy task returning to her love – she’ll have to get past Jafar and the Red Queen first.
