Princess Rosalie

Princess Rosalie Red Swan-Jones  (Lucy Hale), mostly referred to as Princess Rosalie is the daughter of the Savior Emma Swan and Captain Killian "Hook" Jones, the younger half-sister of Henry Mills, Jr. and is the protagonist of the second half of Story of the Saviors.

She is the (former) adoptive daughter of the Black Fairy and the adoptive sister of Gideon. Rosalie was under a sleeping curse in a form of grief. However, her adoptive mother woke her.

Before Birth
While on a rescue mission, Emma learns that she is pregnant with Killian's child. One night while sleeping, Emma is visited by a mysterious fourteen-year-old girl. Rosalie tells her mother to not "forsake her". Remembering the words coming from Neal, Emma demands to know who the fourteen-year-old is again. However, Rosalie refuses and has her mother woken up to see no one is in the room.

Again, the mystery girl shows up again in Emma's dreams, making the young woman very confused at this turn of events. Emma asks the girl for her name, but Rosalie does not respond and tells her to not forsake her again. Finally, tired of these nightmares, Regina detects Emma through her magic, and finally confirms that Emma is pregnant with Killian's child, leading Emma to assume that the girl in her dreams is her and Killian's unborn daughter.

Figuring out it's enough, Rosalie reveals that she is indeed Emma and Hook's daughter. Upon this discovery, Emma goes to her daughter and reaches out to touch her daughter's cheek before Emma wakes up into reality.

Birth
Poisoned with the aging potion simultaneously as Belle, Emma rapidly goes into a painful labor, giving birth to a baby girl. Emma decides to name hers and Killian's child Rosalie at Killian's suggestion. Henry goes to see his newborn sister before she is handed to Blue for safekeeping along with Belle's son, whom she names Gideon after the hero in her book. However, as Blue flies off with Rosalie and Gideon, the Black Fairy intercepts Blue as they both fight over the infants. The Black Fairy succeeds, stealing both the children, while taking the daughter of the Savior as a prize.

She takes them back to her realm, where she raises them harshly. The fairy attempts to make Emma's and Killian's daughter to grow dark. However, Rosalie refuses to be tortured. She only has Gideon there to comfort her, both agreeing to be siblings. From time to time, he reads her the book, Her Handsome Hero to her.

The dark fairy one day sees them reading the book and asks them if they want to be like the hero in this book, to which Gideon says he wants to while Rosalie remains quiet in the background. Purposefully, the Dark fairy tortures a boy named Rodger while keeping their cell door unlocked. However, Gideon is too scared to do anything as he holds Rosalie close to him.

Gideon, fearing to lose Rosalie and after learning how to deal with Dark magic, and fourteen years of torture, Gideon gets her a bean that will help her get back to Storybrooke. Rosalie steals squid ink from the Black Fairy and freezes her. The young girl tells her adoptive mother that she will no longer be the Black Fairy's slave, and calls her  a "monster" and says she's no different than her own son. Taking the magic bean, Rosalie jumps through the portal to be reunited with her family while fearing for Gideon.

An hour before Gideon arrives, Rosalie enters through a portal as a now fully grown fourteen-year-old girl, with her return witnessed by the Dwarves after spotting the Evil Queen leaving Granny's diner. The young woman now goes to confront her parents where she is intercepted by several of the dwarves. Rosalie not in a mood for that, just puts them all to sleep as she makes her way to her father's location. Just at that moment, Gideon returns Rosalie explains her origins to her father of how she had thought of the past fourteen years as being a very terrible time, but it was the memory of Rosalie's parents that kept her going. Her grandfather, David attempts to calm his granddaughter down and Henry informs Rosalie that their mother is still missing. Rosalie, now mad as ever and lost without having both of her parents, tells Killian that if he needs her, she will be staying in the Storybrooke Wilderness Park near the Toll Bridge, or to inform her that her mother returns or not before disappearing in a cloud of rose pink smoke

Rosalie calls for Gideon, who appears right in front of her, tells Rosalie that the past fourteen years without her had been miserable, with Rosalie sad that she had left him. However, Gideon feels no ill-will towards her since he didn't want her to suffer like he had. Rosalie, afte rsuffering visions of a hooded man killing her mother, inquires if Gideon is the man that will Kill Emma. Gideon reasons that he must do it to usurp Emma's savior Powers and kill their evil (former) adoptive mother Gideon offers her to join his cause. However, Rosalie wants no part of this and tells him that if he wants to be a hero, then he should learn how to act like one. Gideon tells her to "think it over" before he disappears calling her "sister" before vanishing. After the battle between Emma Swan and Gideon Gold, Rosalie appears to her mother and the rest of her family, scared of confronting her mother for fourteen years. Emma, when she sees Rosalie, remembers that this is the grown daughter of the girl in her dreams. Emma goes forward and gives her daughter a hug.

However, Emma is also sad the same way Snow White and David were when their daughter already grew up and they missed the experience and Emma wishes to not have that same experience with her.

Personality and Traits
Due to being raised by the Black Fairy, Rosalie was taught to be a villain and molded into a perfect apprentice, to ensure darkness in her hearts. However, due to the fact that she only lived there for fourteen years, Rosalie is not as dark as her brother, Gideon. In fact she does disappear in rose pink smoke in a reference to her name, "Rosalie" being related to "rose."

She is dedicated in protecting her mother from her adoptive brother

While Neal had discouraged Emma from trying to resurrect Hook, Rosalie pushed her mother to do the opposite, but to not forsake her own daughter at the same time. Giving up Rosalie for the sake of her safety made Hook immediately miss her, and couldn't rest knowing whether is daughter is alive or not.

However, she claims she would feel nothing if anything were to happen to her. Her real mother dying prompted Rosalie to get the Sleeping curse from Zelena and put herself under it. However, her plan ultimately fails when the Black Fairy can indeed wake Rosalie up with true loves kiss, but Rosalie knew that her mother wouldn't be able to do it until Gideon is forced to give Rosalie true love's kiss.
