ABC's popular fairytale drama is set to premiere its episode entitled "Heart of Gold" on Sunday, April 12 at 8PM. The title suggests that the episode's main focus will be on Rumple (Robert Carlyle).

Rumple has been on a mad quest for power as of late, desperately trying to find his own 'happy ending'. In order to do that, he must find the Author (Patrick Fischler) of the storybook in order for him to secure the happy ending that he felt he was deprived of for so long. The Once Upon a Time Season 4 Spoilers hints that Rumple would soon employ someone as desperate as he is- Regina (Lana Parilla). Knowing how Rumple does his dealings, he will most likely blackmail Regina into doing his bidding. Or the pasr few episodes, Rumple would always choose the quest for power. Will 'Heart of Gold' show Rumple's change of heart? Will he finally be reunited with his beloved Belle?

The Once Upon A Time Spoilers have also hinted that Robin Hood and Maid Marian will be back in Storybrooke.  Fans of the Robin Hood and Regina pairing have had their hearts broken when Maid Marian made her return to the series, making a potential threat to the 'Outlaw Queen' tandem. Leaked photos have shown Maid Marian and Robin Hood spending some quiet time together in the Enchanted Forest. Could this mean the end of the Outlaw Queen pair?

Show creator Edward Kitsis has teased to fans that the romance between Robin and Regina is "far from 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."  Kitsis said. Outlaw Queen has become quite the fan favorite, and viewers have been anxious to see that Regina will get the happiness that she has been denied of for so long.

Could fans see a chance for Regina's happy ending in 'Heart of Gold'?  Be sure to tune in to ABC on April 12 at 8PM ET.
