'Once Upon A Time' Season 5 News: Captain Hook Seeks Revenge Against Gold [PHOTOS]

This coming Sunday on ABC's hit series 'Once Upon a Time', Captain Hook does battle with a former Dark One - his longtime nemesis Rumpelstiltskin.

Meanwhile in Storybrooke, Emma, Mary Margaret, David, Regina and other characters embark on a new mission — one that apparently requires each person’s "dream-catcher," as seen in the slideshow, while Zelena apparently seeks some quality time with her and Robin’s newborn daughter.
