We are really excited about the all-new episode of Once Upon a Time which airs tonight, as ‘Fruit of the Poisonous Tree’ will give us yet another insight into Regina’s backstory!

Tonight at 8/7c on ABC, prepare to meet Snow White’s father King Leopold (played by Richard Schiff), while in Storybrooke Sidney takes center stage! The description reads:

Sidney asks Emma to join his search for evidence that will reveal the extent of Regina’s corruption to the people of Storybrooke; and Mary Margaret and David continue their secret meetings. In the fairy-tale world, King Leopold is granted three wishes by a genie, but must be careful to use them wisely.

Watch the promo:

So David and Mary Margaret seem to begin an affair. And King Leopold meets a genie – is Aladdin nearby?! We can’t wait to find out!
