could rose be susan (doctor’s grandchild) because her gallifrey name means Rose and she was also 19 years old like Rose.(It is not spoiler it is a theorie of mine)
@kelbesh if you dont watch yhe 5 6 and 7th season you wont probably understand anything because that’s where 11th doctor’s born.At least before watching 50th anniversary watch The Name Of The Doctor(7th season finale).Won’t tell everything but better than nothing.
