According to Wet Paint, "Once Upon a Time" season 3 episode 16 is titled "Not Easy Being Green," which is not about a hint at Rebecca Mader's upcoming role as the Wicked Witch.

Spoilers confirm that the Wicked Witch will be introduced during the March 9 mid-season premiere of "Once Upon a Time."

In addition, Belle will finally make a major return to the series, and will meet Lumiere, played by Henri Lubatti.

Most excitingly, spoilers confirm that fans have not seen the last of Red Riding Hood on "Once Upon a Time."

"I'm not gone from 'Once.' Red Riding Hood just kind of disappeared into the mist. I'm told she will be back but that's up to [executive producers] Adam [Horowitz] and Eddy [Kitsis] when that happens," said actress Meghan Ory according to Zap2it.

And finally, the "Once Upon a Time" season 3 finale is said to feature a wedding. But who will the couple be? Rumple and Belle, Emma and Hook, Regina and Robin Hood?
