Once Upon a Time in Wonderland takes a detour away from the colorful landscapes and explores the dark side of the Knave of Hearts’ corrupt past. Check out a clip below!

Once Upon a Time in Wonderland is all about exposing secrets on this week’s episode, “Forget Me Not.” Our photo post previews a scene from Will Scarlet, the past self of the Knave of Hearts, and his encounter with Robin Hood’s Merry Men. The merriment does not last for long after Will steals more than the group bargains for. The line of bad behavior that follows the flashback with Robin is drawn thick as the Knave leads Alice into a dark land, the Underworld.

Check out their arrival below:

Will Scarlet’s debts are not forgotten in the dark corners of the Underworld. But why exactly are Alice and the Knave venturing to the Underworld? All signs point to the Knave trying to atone for his sins by aiding Alice’s search, no matter the cost to his morale.

Perhaps the most interesting development arriving this week, is the mystery of the White Rabbit’s debt to the Red Queen. Yesterday, it was announced that Whoopi Goldberg will join John Lithgow as the White Rabbit’s wife, but not until episode 8. Let’s hope the Rabbit family remains safe until then!
