I'm on the side of "The Fugitive Doctor is season 6b"
"Why was her TARDIS a police box?" She comes after the second Doctor!
"Why doesn't she recognize the sonic screwdriver?" Hers looked different! And she didn't say she never had one, just that she didn't need one, which is exactly the kind of thing the Doctor would say after she's lost Jamie
"Who was she working for?" The CIA
"Why is she so combative?" She's a CIA agent and she comes right before the third Doctor! He got it from somewhere!
"Why doesn't the thirteenth Doctor remember being her?" The Time Lords wiped her memory before exiling him to Earth. It's perfectly in character
She has exactly the jaded attitude and aggressive abilities of a Doctor who has just been through the War Games. I'm just saying. It makes sense
