(Nancy is hugging Jaime, nanogenes are flying around…)
Doctor: Come on, you clever little nanogenes. Figure it out. The mother, she’s the mother. It’s got to be enough information. Figure it out.
Rose Tyler: What’s happening?
Doctor: See? Recognizing the same DNA. (Doctor runs to Jamie) Come on. Give me a day like this. Give me this one. (takes of Jamie’s mask, revealing his face) Welcome back! 20 years to pop music, you’re gonna love it.
Nancy: What happened?
Doctor: The nanogenes recognized the superior information. The parent DNA. They didn’t change you because you changed them. Mother knows best.
(Later…)
Rose Tyler: What are you doing?
Doctor: Software patch. Gonna email the upgrade. You want moves, Rose. I’ll give you moves. (send nanogenes towards “The Empty Child victims”) Everybody lives, Rose. Just this once! Everybody lives!
