One of the things many viewers are anticipating in “Once Upon a Time in Wonderland” is some crossovers from “Once Upon a Time.” We already got a taste with Grumpy/Leroy (Lee Arenberg) making an appearance in OUATW. However, co-creator and executive producer Zack Estrin recently said fans shouldn’t expect an all out crossover anytime soon.

"Right now in the beginning we're going to make sure that each show lives on its own," he explained in a recent interview with EOnline.

However, viewers shouldn’t be surprised if they see more mini crossovers like the one from the premiere.

"Wonderland is its own show, but down the road, who knows? You may see a familiar face or two making their way over to Wonderland,” he teased. “Certainly there are some who started in Wonderland who could always return."

According to TVLine.com, that may happen sooner than you think.

The website reported that in next week’s episode we’re going to see our favorite green-hooded vigilante (outside of Oliver Queen of course) make his way into Wonderland as part of a flashback. Apparently, the Knave of Hearts (Michael Socha) was once part of the Merry Men lead by Robin Hood (Sean Maguire). In fact the Knave (who used to be Will Scarlet) suggests that the group of thieves should take something from Maleficient’s castle.
