Once Upon a Time S05E03 Still - H 2015

[Warning: this post contains spoilers for Sunday's episode of Once Upon a Time, "Siege Perilous."]

Dark Swan (Jennifer Morrison) isn't the only villain the people of Storybrooke will have to contend with on Once Upon a Time.

Though Arthur (Liam Garrigan) established a friendship with David (Josh Dallas) in present day and in the flashbacks to Camelot, he actually was just playing on David's desire to be known for more than waking up Snow White (Ginnifer Goodwin) with a kiss.

In flashbacks, a secretly-returned Lancelot (Sinqua Walls) warns Mary Margaret that Arthur is the true danger to Camelot. The true depth of his betrayal was showcased in Storybrooke as Arthur had a loyal servant stage a robbery  and then Arthur asked him to kill himself to keep their secret safe.

The show will dive into the complicated past of Arthur, Lancelot and Guinevere (Joana Metrass) in an upcoming hour. "We're going to learn about [Lancelot's] past and the iconic love triangle," Once Upon a Time co-creator Adam Horowitz teased during the show's New York Comic-Con panel.

As Arthur's bad deeds fester in the background, Dark Swan's actions will have a more immediate consequence. Fresh off of Dark Swan's attempt to manipulate Hook (Colin O'Donoghue both as an attempt to get his sword as a tool to help wake up Rumple (Robert Carlyle), and because there is a part of Emma that remains wanting to be with the man she loves  she'll soon focus her attention on someone else Emma holds dear.

"Coming up in two weeks… she turns her sights towards Henry and trying to get his trust," Once Upon a Time co-creator Eddy Kitsis previewed.

And with Rumple now awake  but no longer tied to the Dark One  "he is a five [on the danger scale]," Kitsis said. "He has no magic, but he has the wisdom of everything he's gone through… he's more likely to run away."

Rumple's newfound heroics could come in handy when the truth about the latest curse is revealed. The producers confirmed that a heart was indeed crushed to enact it (though they offered no clue about which person had to die to make this happen) and there's a twist in store.

Said Kitsis, "When you find out why their memories are taken, if you don't like that twist, let us know on Twitter as always."

Once Upon a Time airs Sundays at 8 p.m. Are you excited to see what Dark Swan does with Henry and Rumple?
