There will be another big kiss on an upcoming episode of Once Upon a Time, though the two participants are an unlikely pair.

Regina Teaches Emma More Magic In Upcoming Episode?

A new photo has been released featuring Zelena/the Wicked Witch (Rebecca Mader) and Rumplestiltskin/Mr. Gold (Robert Carlyle) sharing a kiss. The photo, posted by TV Guide Wednesday, features Zelena and Rumple sharing what looks to be a very passionate kiss. Are there ulterior motives for the pair to be exchanging a lip-lock, though?

"Either the Storybrooke Tinder app has an extremely limited pool of potential dates or there's more going on here than appears at first blush," executive producer Edward Kitsis teases in the TV Guide report in conjunction with the photo.

The report also notes that Zelena requires help in stealing various virtues from the residents of Storybrooke, and Rumple proves himself to be a good assistant. Such virtues include Regina's (Lana Parrilla) heart and Charming's (Josh Dallas) courage.

The episode featuring Zelena and Rumple's big kiss will air on April 20, an episode titled Bleeding Through.

Before this, Zelena will get her big focus episode on Sunday in an episode called It's Not Easy Being Green.

"This week is the showdown," Kitsis says in a different TV Guide report about Zelena vs. Regina. "We will find out why the witch is green and what she really wants."

Once Upon a Time season 3 airs Sundays at 8 p.m. on ABC.
