It is only less than a week before ABC's Once Upon A Time returns for the continuation of its third season. While the fantasy drama is out, casts and other staff have been very generous in giving clues on what to expect once the comeback happens. Four days before the ninth episode, the show is not yet done in teasing fans as more Once Upon A Time Season 3 Spoilers are given out.

In an interview with TV Guide Magazine, Jennifer Morrison, who plays Emma Swan, said that her character and the rest of protagonists will meet a new dark force that will definitely get into the heads of the viewers.

Wicked Witch of the West, who will be portrayed by Lost alum Rebecca Mader, is one of the most anticipated new characters in the third season. According to Morrison, this new antagonist will bring so much suffering for their characters.

"She's possibly the most terrifying villain we've ever had because her desires and intentions are very unclear. The show has begun to feel eerie, in a great way. I read the scripts and go, "Oh, God, what's coming next?" she told TV Guide.

As if the Wicked Witch is not enough, Captain Hook (played by Colin O'Donoghue) will also have his hands full on a plateau of enemies.

"There will be many pirates appearing in the second half of season 3, as Hook's nemesis Blackbeard will make an appearance. Hook will have Henry by his side, according to Horowitz, who said that "Henry and Hook are quite the team," a report from Enstarz wrote.

Once Upon a Time co-creators Edward Kitsis and Adam Horowitz also gave some tid bits about the fate of Hook when he visits New York to search for Emma. According to early press releases, Hook received a message saying Emma and his son are in danger. Of course, he will hurry to rescue them.

"The message Hook got COULD be a trap, but that is a mystery we're spending an entire episode on," Horowitz said.
