Comic-Con 2015: Everything あなた need to know before the Once Upon a Time panel 

'Once Upon a Time' First Look: The Dark Swan rises!

'Once Upon a Time' finds its King Arthur

'Once Upon a Time': Sinqua Walls returning as Lancelot

With the Dark Swan rising, who will step up to protect the residents of Storybrooke? And Can Emma be brought back from the darkness? We hope to get some answers on that and much more during the

panel at Comic-Con on Saturday. To prepare for the big event, EW is here to give you a refresher on where the ABC fairy tale drama left off:

Where we left off: After the fairy tale world was turned upside down by the Author, Henry (Jared Gilmore) was able to save the day. But upon their return to Storybrooke, the darkness within Rumple (Robert Carlyle) was accidentally set free, so Emma (Jennifer Morrison) decided to sacrifice herself and become the new Dark One.

What we know about season 5: Now trapped with the powers of an ancient evil, Emma will be fighting her dark urges while discovering her new powers as the Dark Swan — though she’ll put a twist on those powers by potentially using love as a weapon. Meanwhile, the residents of Storybrooke will be on the hunt for Merlin, who may be able to set Emma free. Their quest — which will see Snow (Ginnifer Goodwin) and Charming (Josh Dallas) cross some lines to save their daughter—will bring out a new Savior, while also introducing King Arthur and Guinevere. Plus: Lancelot (Sinqua Walls) returns! Get more scoop here and here.
