Before the Curse
At some point in her life, the fair Lady Marian became involved in a relationship with the Sheriff of Nottingham, but was willingly stolen away by Robin Hood with whom she fell in love with, and the two of them lived a life on the run. Eventually, Marian became pregnant with Robin's child but she also fell gravely ill, and so Robin set out to find a way to save her.

When Rumplestiltskin is yelling at his maid Belle for crying too loudly, he hears a noise upstairs and goes to investigate. He and Belle discover a thief, Robin Hood, in the room attempting to steal Rumple's magic wand, to which the Dark One is very unhappy. Robin fires an arrow at Rumple from his bow, one that contains magic so that it never misses its target, however, due to Rumple's own supply of magic, he is able to pluck the arrow fired at him from out of his chest and take Robin prisoner. The Dark One spends a while painfully torturing Robin, much to the dismay of Belle, and when the wizard leaves his castle for a while, Belle sneaks down into the dungeons and gives Robin some water, before untying him so that he is able to run free. He asks her to come with him but she says that if she does that, her family will lose Rumple's protection in exchange for her servitude, and so the thief wishes her luck before fleeing the castle. Rumple grows furious at his maid for letting Robin go and even more so that the thief escaped with the magic wand, and so vows to kill him with his own bow in front of her. After gathering the information he needs from the Sheriff of Nottingham, Rumple and Belle find Robin in Sherwood Forest where the thief uses the magic wand to heal a sick Marian. As she steps out of the carriage, Rumple sees she's pregnant, and as he doesn't want to leave a child without a father, when he fires the arrow, it misses, and Robin Hood and Marian are able to ride off with one another to safety.
