"Once Upon a Time" Season 5 ended in 2015 with episode 11 titled "Swan Song," in which Captain Hook (Colin O'Donoghue) killed his father who abandoned him as a young boy while the family and friends were set to be sent to the Underworld. The fairy tale dramatic series is set to return on ABC on March 6.
In "Swan Song," Zelena (Rebecca Mader) vowed to get sole custody of her daughter and was sent back to Oz by Regina Mills (Lana Parrilla). Hook killed his father in the Enchanted Forest when Regina recruited him to kill Cora Mills (Barbara Hershey).
After turning Excalibur on the previous Dark Ones, Hook asked Emma Swan (Jennifer Morrison) to sacrifice him with Excalibur. After finding out that Mr. Gold (Robert Carlyle) used the situation to tether the darkness back into himself, Emma then blackmailed him into helping her bring Hook back from the Underworld.
What fans can expect from "Once Upon a Time" Season 5 episode 12 titled "Souls of the Departed," which is written by Edward Kitsis and Adam Horowitz, is the characters' journey to the Underworld. Recently, Josh Dallas, who plays David Nollan, talked about what they are about to encounter there.
"It's a place that, once they get there, they're going to discover that possibly some of these people can be saved and brought out of there because maybe they're misplaced in this world," Entertainment Weekly quoted Dallas as saying. "We're going to meet some people down there that maybe you don't expect or you haven't seen in quite a while."
According to Dallas, it is likely that a member of David's family is in the Underground. He added that his character and Mary Margaret Blanchard (Ginnifer Goodwin) will come across a particular person there.
Meanwhile, Dallas and Goodwin were spotted on Feb. 1 departing from LAX with their son, Oliver Dallas. The pregnant "Once Upon a Time" actress was wearing a flowing maxi dress, Daily Mail reported.
