Once Upon a Time star Josh Dallas recently spoke about the upcoming arc in the Underworld and alluded to one character in particular showing up there.

Dallas, who plays Charming on the series, talked to Entertainment Weekly recently about the possibility of characters being saved from the Underworld.

"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," Dallas said. "We're going to meet some people down there that maybe you don't expect or you haven't seen in quite a while--maybe a family member of David's we might see down there. There is definitely a particular person down there for David that he's going to come across, and Mary Margaret will come across that person too."

The report then links to a previous article revealing the identity of the person Dallas is talking about. That article states that Charming's twin brother, James (also played by Dallas), will be present in the Underworld.

Prince James was last seen in the season 2 episode called "Tiny"--however, his death was chronicled in the season 1 episode "The Shepherd". Behemoth (Robert Meilet) engaged in a duel with James, which wound up killing both of them.

Once Upon a Time returns for the second half of season 5 on Sunday, March 6 at 8 p.m. ET/PT on ABC.
