Rose is one of member Society's Assault unit and also a scout troops
Initially, very little was revealed about Rose's past or history. She simply showed up as "the new girl" at Jake's school (see "Old School Training"), and nothing was really unveiled about her early childhood until later parts in the series.
According to her, she's been a part of the Huntsclan for as long as she can remember (she remarks in "Dreamscape" that her earliest memory is her "lying in her Hunts-crib, crying for her Hunts-nanny to change her Hunts-diaper"). She ascended to become an apprentice for the Huntsman while working in the field in New York, and was personally taught by him about magical creatures (namely of their disgusting and unnatural nature, as hinted in "Breakout") and in the methods of hunting.
In episode 12, "Ski Trip", Jake discovers that Rose is Huntsgirl. Then, in episode 21 "The Hunted", Jake shows her his identity as the American Dragon.
Rose was told by the Huntsman that both of her biological parents died shortly after she was born, afterwards being taken in by the Huntsclan. However, in "Dreamscape", it's revealed that her parents (as well as a twin sibling) did not die. Rather, the Huntsman, as well as Huntsclan members working undercover in the hospital, kidnapped Rose shortly after her birth, after noticing her "Mark of the Huntsclan" birthmark. The names and whereabouts of her family remained largely unknown until "Homecoming", where she and her family moved to Hong Kong, but they have not shown her twin. They did not say the names of her family, but they returned in "The Hong Kong Longs".
After Rose's wish for all Huntsmen to be destroyed—herself included— was granted, Jake immediately wished that Rose had never become a member of the Huntsclan. This ended their relationship, until the series finale "Hong Kong Longs" when Rose regains her memory after seeing the picture of her and Jake at the dance and she returns to help him fight and defeat the Dark Dragon.
