You were Killian’s daughter, and Henry had been taken by Pan and the Lost Boys, so your father had set up a quest to get him back, not knowing the danger he was putting you in.

As the ship crashed ashore, Killian, Emma, and you climbed onto the beach of Neverland. You never really cared nor understood the rivalry between Pan, his Lost Boys, and your father. All you cared about was getting Henry back. Henry is Emma's son.

Your father cares deeply about you, even if he doesn't show it sometimes. All he wants is to keep you safe and out of harms way. Whilst your father was walking in the forests alone to collect firewood, Pan approached him.

"I'll make you a deal, Killian. Hand over your daughter, and I'll give you Henry. I know you want nothing more than to be the one who hands Emma her son back. I know you love her." Pan announced with his iconic demonic smirk.

Your father denied his offer and went back to the area where you, Snow, Emma, David, Regina, and Rumple were.

A few days later. You, Emma, David, Snow, Regina, Rumple, and your father were fighting Pan and his lost boys after Regina had used her magic to 'cheat' and find Pan through the map he gave to Emma. The map would only show where Pan was when Emma expected who she was. She didn't know how to do so, so Regina used her magic to make the map take them all to Pan.

During the fight, Pan grabbed you. He shouted, turning the fight to a holt. "Well, well, well. Would you look at this. I have Killian's daughter. I'm gonna take her now. Maybe this will teach you not to cheat. Remember, cheaters never win." And with that, Pan, his Lost Boys, and you disappeared.
