A little "script tease" was released by "Once Upon a Time" executive producer Adam Horowitz for the midseason premiere of the show's fourth season.

Horowitz shared a fraction of the script for episode 13 in his Twitter account, saying: "How about a frustratingly tiny #OnceUponATime #scripttease for the March 1st premiere? Happy holidays!"

The post was inserted with a puzzling line from a script, wherein a voice over says, "That means it's ready."

To make fans wait in agony, the executive producer did not release added information about what that line is all about or to whom or what is it addressing.

Then Horowitz posted another tiny teaser at the beginning of the year. This time, the mini teaser hints that there is something in store for ex-evil queen Regina (Lana Parrilla) in the upcoming episode of "Once Upon A Time" season 4. The line that Regina will say in the midseason premiere is "Wait. Don't --" However, there are also no details about what the former baddie is pertaining to. 

In the last episode before "Once Upon a Time" went into a winter break, Regina was over the moon when Robin Hood (Sean Maguire) chose to leave his wife Marian (Christie Laing) for her. But just like any other fairy tale, it is quite impossible for villains to have a happily ever after. So when the Snow Queen (Elizabeth Mitchell) put an icy spell on Marian, Robin decided to rescue his wife. Regina then tore away the photo in the Storybook that depicted her first encounter with Robin in the Enchanted Forest of the past. 

However, Regina's hopes for a happy ending has not died yet as Henry (Jared S. Gilmore) found a hidden room in the Sorcerer's mansion, which could possible lead to the discovery of the Storybook author. Does the teaser mean to tell viewers that Regina is already rewriting her story? 

"Once Upon a Time" season 4 returns with its remaining episodes on March 1.
