When 'Once Upon a Time' Season 4 Episode 18 titled 'Heart of Gold' airs at 8:00 pm on Sunday, April 12, via ABC, fans will see the show focus on Robin Hood (Sean Maguire) and Maid Marian (Christie Laing).

According to IB Times, though the title of the upcoming episode hints that the show will focus on Mr. Gold, alias Rumpletiltskin (Robert Garlyle), some leaked images pertaining to 'Heart of Gold' reveal that the expert archer and his beloved are in the Enchanted Forest. The photographs show that the couple is very happy, as they are spending quality time in one another's company. However, it remains to be seen what the storyline has in store for them.

Meanwhile, 'Once Upon a Time' executive producer Eddy Kitsis had previously teased that the romance between Hood and Evil Queen Regina Mills (Lana Parrilla) is far from over. In an interview with Entertainment Weekly, Kitsis said, "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."

However, as ABC has not yet released the official synopsis of 'Heart of Gold,' fans of the series can suppose that the characters of Maguire and Laing may either lead them to some dark secrets of Mr. Gold or even open a romantic episode for the Evil Queen.

In the meantime, Daily Mail reports that on-location photographs of 'Once Upon a Time' Season 4 show Hood and Marian wearing contemporary outfits. The skilled archer is shown chasing a thief who may have stolen his partner's handbag, while Laing's character is seen shouting after her love across a busy street.

All said and done, fans will have to wait until April 12 to know whether or not the seemingly happy couple will come out of Storybrooke.
