The Doctor:  I just want you to know , there are worlds out there , safe in the sky because of her . That there are people living in the light , and singing songs of Donna Noble , a _ thousand _ , million light years away . They will never forget her , while she can never remember . And for one moment ... one shining moment ... she was the most important woman in the whole wide universe .
Sylvia Noble: She still is . She 's my daughter .
The Doctor: Then maybe you should tell her that once in a while .
