Horowitz faced some problems with the Final Draft software, which is used by screenwriters. The software apparently shut down while he was typing, and it did not save his file.

New characters will be introduced in the show from the Land of Untold Stories. The TV series is looking to cast a Middle Eastern/Arabic or Northern African male in his 30s to play the role of Sindbad in “Once Upon A Time” Season 6. The character is described as “roguishly charming and quick-witted hero who knows the power of kindness but as of late has lost faith in his ability to lead his people,” TV Line reports.

Another character being cast for the show is Scheherazade, the lady who told the “One Thousand and One Nights” stories. The character is being described as a “regal Middle Eastern/Arabic beauty who never backs down from a good fight and can go toe-to-toe with even the toughest adversaries.”

The main villain in “Once Upon A Time” Season 6 is Hyde (Sam Witwer). Horowitz teased that the show will now examine how Hyde’s presence will affect the day-to-day life in Storybrooke, Entertainment Weekly reports. He also revealed that the TV series now aims to get back to the “Season 1 and 2 vibe of small town stories.”
