Blame it on Rumpelstiltskin. “Once Upon a Time” composer Mark Isham may have been hit by a dark spell. The composer allegedly posted the Season 5 premiere title online … before quickly deleting it.

According to SpoilerTV, Isham took to Instagram to share the cover of the Season 5 premiere script. If the photo is real, the title for the September 27 episode is “The Dark Swan.” A screen grab of the image was captured, however the site notes that it is no longer on Isham’s Instagram – meaning that somebody potentially told the composer to delete it.

“Once Upon a Time” fans are used to seeing script covers posted online. But the big difference is that the photo usually comes from series co-creator Adam Horowitz. The co-creator has a history of keeping viewers on their toes by posting little tidbits about new episodes.

Horowitz’s first update about the Season 5 premiere came on June 17 when he revealed that he was writing the script and “had to create a new folder” for the document. He followed up on June 22, posting that he was “rewriting” the upcoming episode. Horowitz has yet to comment on the alleged title for the premiere, however big scoop could be on its way very shortly.

On Saturday, July 11, Horowitz will be on hand to talk all things “Once Upon a Time” at the 2015 San Diego Comic-Con panel. He will be joined by series co-creator Edward Kitsis, and stars Ginnifer Goodwin, Jennifer Morrison, Robert Carlyle, Lana Parrilla, Josh Dallas, Emilie de Ravin, Colin O’Donoghue, Sean Maguire and Rebecca Mader. Those in attendance will be treated to scoop about Season 5, which will feature “unexpected twists, evolving characters, new adventures and new rivalries.” And if that wasn’t enough, fans will also get an “exclusive sneak peek at what’s in store.”
