Wired writes about Gallifreyan incest:
“Doctor Who star David Tennant is currently dating Georgia Moffett — the actress who portrayed The Doctor’s daughter in the Who episode of that same name.
Moffett is the daughter of Peter Davison, who played The Doctor’s fifth incarnation. So, she’s a Doctor’s daughter playing The Doctor’s daughter. She’s also the first Doctor’s daughter who played The Doctor’s daughter to date The Doctor.”
| Georgia Moffett is insanely hot and, if you haven’t seen the episode, will be returning to Doctor Who at some point in the future. Seeing as she was built 100% from Gallifreyan DNA, you’d have to wonder why the tech used to create her isn’t used to repopulate the Time Lords and, frankly, any other species in danger of dying out. |  |
Or maybe the Doctor likes to be a lone ranger standing on the gates of oblivion and quite likes the fact they’re all dead – and only resents the perennial resurrection of The Master and treats this new ‘daughter’ as an interloper.
