During an adventure in the dream realm, Rose discovered not only what her parents looked like, but that she also a has a twin; slightly older, having been born first. Whether this twin is a brother or sister is unknown.
She also learned the truth of how the Huntsclan stole her from her family.
- Many fans of American Dragon: Jake Long thought of names for the twin if a sister, something which would be a flower name like Rose's, like Lily or Camelia.
- It is never explained why, but Rose's twin never appeared again after this one appearance, not even as a teenager like Rose. It has been suggested by fans that the twin died.
- Some may believe that Rose's twin might be in some boarding school.
- Others may believe that, as a consequence of Jake wishing Rose had never been taken by the Huntsclan, her twin was taken instead.
- Not possible. The twin had no dragon tattoo, else they would have been taken too.
