In the Character's Past
In the decades before the first curse began, Ruth and Robert are the parents of newborn twins David and James who require serious medical attention, or they will die. When Rumplestiltskin shows up and sees them, he offers them a deal that results in Rumplestiltskin taking James as part of a deal he made earlier with King George in exchange for giving the parents medicine for David.
Six years later, King George wants to know the whereabouts of Prince James who has been abducted. Robert, who has become a alcoholic, hears this news and believes that finding the son he gave up will solve the family’s problems. Masquerading the quest as a supply run, he is then given a coin by David (the same one that The Evil Queen returned to him as a grown man in Storybrooke) as a sign of good luck. The first stop Robert makes is to see Rumplestiltskin in his castle. Rumple, emphatic to Robert's desire to make things with his son, then looks into a crystal ball and located James to a place called Pleasure Island. As part of a deal, Rumplestiltskin gives Robert a ticket to the island to find James, he takes the hair strand from Robert (only to discard it as he really had no use for it). When Robert arrived to the amusement park-themed Pleasure Island, he is met by Pinocchio, who already has met James. Pinocchio leads Robert to his birth son, who really ran away because George wanted to make him a knight. Robert offers to take James to his real home, revealing he's the boy's true father. As they attempt to escape, the barkers goes after them and they are caught by King George outside, who asks for James back. Robert strongly refuses the offer for returning James, so the guards are ordered to kill him and make it look like an accident. James is then handed over to King George to continue his life as a prince (which leads to his corruption and death in adulthood).
The truth of Robert's death is later revealed. It turned out that as Robert was about to murdered, a group of pirates intervened. They then killed the guards, with Robert, despite his pleas, soon being among the victims. Robert's murderer was none other than Captain Hook.
The mystery surrounding Robert's murder is starting to have a strange effect on David to the point of seeing visions, as his father starts giving David cryptic messages to find out the truth. Meanwhile, Hook scheduled a meeting with Archie on how to propose to Emma, but is worried about the reaction from David. When Hook later sees David, he noticed how obsessed David has become with finding out with who murdered Robert, and now wants Hook to help him, albeit reluctantly from the pirate. Later on, David sneaks into Emma's place to look for items to help him. Hook agrees to play lookout when Emma approaches and he convinced her not to go in the place. David then finds a spell book and with Hook's help try to follow the instructions, and it leads them to a clue which reveals that Robert may be on Pleasure Island.
David and Hook go to see August to ask about Pleasure Island. He reveals what Robert was really doing: finding James and reuniting his family. August removed the pages that could include more information about Robert and starts looking. By now, Hook is starting to worry David is seeking revenge, but David turns on Hook by handcuffing him to a bike rack and drives away, having a hunch of who his father's murderer is. David goes to the asylum to confront the now-jailed Albert. The man reveals Robert was offered temptation as a reward for finding James, but the sober shepherd rejected and was sentenced to death. Angered at George for he did to his family all those years ago, David challenges his former "father" to a fight to the death, only to have Hook intervene and place Albert back in jail before he can be killed. David is still heartbroken to learn his father finally sobered up to save his family only to die for it, and begins fearing he too will fail to protect his own. Hook talks David out of vengeance by stating that Robert was able to face his son as a drunk and questions if he in turn could be able to gaze back as a murderer. Finally letting go of the past with newfound respect for his father, David thanks Hook for stopping him from making a terrible mistake. Hook in return asks David for Emma's hand in marriage and David gives Hook his blessing.
In between the events, the Wish Realm Robin is starting to adjust to life in Storybrooke and after a heated Zelena confronts Regina about the Wish Realm Robin not being able to have any rights to his daughter and leaves, Regina checks on Robin and finds him missing and a picture of Keith, who Robin thinks is the Sheriff of Nottingham from his realm, Regina stops Robin from killing Keith by making him disappear. Regina tells Robin about his real world counterpart having a son and daughter in this realm, and agreed to start afresh with a kiss. Later that night, Regina visited a now awake Snow, and tells her that bringing Robin back was not only a mistake, but is now starting to question how he managed to survive coming to the portal. She even questioned why her kiss with Robin felt like she was kissing paper. It turned out that the Wish Realm Robin had a real reason, and a ulterior motive, when he steals a heart from Regina's vault that he sees as powerful.
Hook is later confronted by August, who told him about the real reason he tore the pages out of the book and gives them to Hook. Seeing and recognizing Robert's picture, Hook recalls that he did the deed, not George's men.
