Watch Once Upon a Time Season 5, Episode 3 Siege Perilous Onlinie

In Camelot, the heroes feverishly work to free Merlin. Determined to help Emma, David embarks on a quest to retrieve a magical relic that Regina could use to communicate with the imprisoned sorcerer; but, when David leaves, Arthur insists on joining him because the dangers ahead are greater than he can imagine. Meanwhile, Mary Margaret discovers the fate of her old friend Lancelot. Back in Storybrooke, Arthur seeks David's help to catch a thief who threatens the safety of the citizens of Camelot. Across town, Emma reaches out to a conflicted Hook as she sets about her plan to draw Excalibur from the stone. From the inventive minds of Lost executive producers Adam Horowitz and Edward Kitsis comes a bold new imagining of the world, where fairy tales and the modern-day are about to collide. And they all lived happily ever after - or so everyone was led to believe. Emma Swan knows how to take care of herself. She's a 28-year-old bail bonds collector who's been on her own ever since she was abandoned as a baby. But when the son she gave up years ago finds her, everything starts to change. Henry is now 10 years old and in desperate need of Emma's help. He believes that Emma actually comes from an alternate world and is the missing daughter of Snow White and Prince Charming. According to his book of fairytales, they sent her away to protect her from the Evil Queen's curse, which trapped the fairytale world forever, frozen in time, and brought them into our modern world. Of course Emma doesn't believe a word, but when she brings Henry back to Storybrooke, she finds herself drawn to this unusual boy and his strange New England town. Concerned for Henry, she decides to stay for a while, but she soon suspects that Storybrooke is more than it seems. It's a place where magic has been forgotten, but is still powerfully close... where fairytale characters are alive, even though they don't remember who they once were. Emma will have to accept her destiny and fight for everything that once was.
