Will we see other Wonderland characters come to Once?
Horowitz: It’s possible. But as far as what we’re planning right now, we’re planning to have [just] the Knave.
Kitsis: We might see a few faces here and there at some point.
Horowitz: The story of Wonderland was always meant to be a one-year, close-ended tale. That tale is coming to a close and we’re not going to be continuing those story strands on Once Upon a Time.
So yes, the Knave is coming back to Storybrooke. So good to have confirmation that news on April Fools’ Day was not a joke.
