Priscilla is a character featured in the extended universe of ABC's Once Upon a Time. She débuts, with her only appearance, in the graphic fiction novel, Out of the Past.
Before First Curse
Living as a thief, Priscilla eyes her next big heist to steal treasures from the king's castle in Camelot while a party is underway. Dressed as a guest, she quickly breaks into room number nine, which contains a large quantity of gold valuables. Shortly after her arrival, another thief named Jefferson enters, and she tries to scare him off by pretending to be one of the king's guards, though he sees through her disguise. Before the real guards reach them, Jefferson considers escaping into his portal hat alone, but Priscilla hauls him with her out a window. Once they are outside, he convinces her to journey into the hat with him. She agrees, and they end up having many thieving adventures together, before falling in love. After marrying, they settle down in the Enchanted Forest and Priscilla births a daughter, Grace, as Jefferson puts his portal hat away. Two years later, their finances are drained, but when Jefferson learns the Clock of Evermore's location, he heads to Wonderland to steal it, hoping to sell it for money. When he doesn't return, Priscilla gains the White Rabbit's help to rescue her husband from the March Hare, although Jefferson insists on retrieving his hat. With the March Hare chasing them, the pair flee upstairs, where Priscilla is fatally wounded by a guard's arrow. Not wishing Grace to be orphaned, she persuades Jefferson to go home without her. As she dies, he holds her one last time before escaping into the portal hat. ("Out of the Past")
