Georgia Moffett, the daughter of Trillian from The Hitchhiker's Guide to the Galaxy
television miniseries, is Random. And Random is half Time Lord
. This explains Random's ability to travel through time, and why Georgia Moffett looks nothing like her father: Her mother artificially inseminated herself with Arthur Dent actor's Simon Jones' semen. And, um, Georgia Moffett is therefore a Hitchhiker's Guide character who has broken through the fourth wall
and become a real-life character, then somehow been generated from David Tennant who she slept with despite being a descendant from a former incarnation of him. And Derren Brown is involved somehow, too.
One of Georgia Moffet's children will be a future Doctor/a relative of the Doctor.
Both their grandpa
played the Doctor, and their mum played a relative of the Doctor.
It may be something as simple as Tennant's baby girl being Susan in a flashback, or as epic as Ty Moffet becoming the Doctor-possibly the 15th Doctor, depending on how long Peter Capaldi and Doctors 13-14 last.
