Grace: Maybe you’re the result of some weird genetic experiment.
Doctor: I don’t think so.
Grace: Well, you have no recollection of family.
Doctor: No. No, no, no, no. Wait, wait. I remember I’m with my father, lying back in the grass. It’s a warm Gallifreyan night.
Doctor: Gallifrey! Yes, this must be where I live. Now, where is that?
Grace: I’ve never heard of it. What do you remember?
Doctor: A meteor storm. The sky above us was dancing with lights. Purple, green and brilliant yellow! Yes!
Doctor: These shoes! They fit perfectly. Yes!
