The Doctor and Sylvia in “Journey's End”

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. [visibly upset] But for one moment, one shining moment, she was the most important woman in the whole wide universe.

She still is. [insistently] She's my daughter!

Then maybe you should tell her that once in a while!
