ABC's fairytale drama "Once Upon a Time" is set to telecast season 4 episode 18 titled "Heart of Gold" on Sunday, 12 April, at 8pm and it could revolve around Robin Hood (Sean Maguire) and Maid Marian (Christie Laing).

Although title of the series indicates that the focus of the next sequel will be on Mr. Gold aka Rumplestiltskin (Robert Carlyle), leaked images show the skilled archer and his lady love in Enchanted Forest. In the photos, the couple is seen happily spending quality time with each other but it's not clear where the storyline will take them.

Earlier, executive producer Eddy Kitsis had teased that Hood's romance with Evil Queen Regina Mills (Lana Parrilla) is not yet over. "We haven't seen the end of it. The story is just at a middle point and although it seemed final, I would definitely keep watching because there's much more to come," he told Entertainment Online.

But since ABC is yet to release the official synopsis and trailers of episode 18, viewers can assume that Maguire and Laing's characters may lead them either to some dark secrets of Mr. Gold or open a romantic chapter for the Evil Queen.

Meanwhile, on-location pictures of season 4 shows Hood and Marian in present day outfit. While the skilled archer is seen chasing a thief who could have probably stolen his partner's handbag, Laing's character is shown yelling after her love across a busy street, according to Daily Mail.

However, fans will have to wait until 12 April to know whether the couple could be out of Storybrooke or not. In the meantime, they can watch the upcoming episode of "Once Upon a Time" season 4 titled "Best Laid Plans" on ABC this Sunday, 29 March, at 8pm, which will be live-streamed here.
