Martha / Jacob
Are we? I think everyone is a story, somewhere. Does that make anything less real? I've heard of all those names before, so it's possible. Or we're from very similar, but different, parallel universes.
Shakespeare existed for you, didn't he? Queen Elizabeth? I met them both, you know. Well, I only saw the queen very briefly.
Oh, I didn't leave all the aliens at home. The Doctor's here, and his TARDIS. This is very like one of my old adventures. But [...] I do see your point. I just tend to get caught up in the adventure of it all, even though I really did mean to stay on my own planet, in my own universe and my own time, with my family and my friends and my job. I still get the thrill of exploring a new place and meeting people from all different places and all different species.
