Once Upon A Time Season 5 Episode 15: The Brothers Jones Sneak Peeks Released

ABC has released two sneak peeks from this Sunday's "The Brothers Jones" episode of Once Upon a Time.

The first clip: "While searching the sheriff's station, Snow (Ginnifer Goodwin) and David (Josh Dallas) find the key to the Sorcerer's mansion. Suddenly, Cruella De Vil arrives and mistakes David for his twin brother, James." In the following clip: "Hook's brother, Liam, is in the Underworld and may have the answer to defeating Hades (guest star Greg Germann): the storybook."

Check out the 2 clips in the videos below.

Finally reunited, Hook and Emma must find a way to defeat Hades so that they can return to Storybrooke with Snow, David, Regina, Robin, Henry and Gold. A surprise visit from Hook's departed brother Liam just might provide the lead they were looking for—others who have tried to overthrow Hades spoke of a book that contained the key to his downfall. Tired of watching from the sidelines, Henry secretly takes matters into his own hands while the others search for the book. Meanwhile, Hades redoubles his efforts to trap the heroes in the Underworld by playing them against one another. In flashbacks, the bond between the two young Jones brothers is tested and strengthened on a merchant ship heading into a dangerous storm.

The episode was written by Jerome Schwartz and David H. Goodman, and directed by Eagle Egilsson.

"The Brothers Jones" episode of Once Upon a Time will air Sunday, March 27 (8:00-9:00 p.m. EDT) on the ABC Television Network.
