The Doctor/Martha and Doctor/Jack "pr0n" that were read out on The Friday Night Project...nobody seems to know who they're by. One of them was thought to be by nostalgia_lj but it turns out that's wrong.
But...Google's showing literally nothing for either of them.
So...did the writers of the show just write some (brief snippets of) (so-called) Doctor Who pr0n? They should join some of the comms, they'd go down a treat...
And as for Mr Tennant acting all innocent...y'don't fool me, mate...
