Title: Two Birds in a Cage
Characters: alt!Sarah Jane, alt!Three, Section Leader Shaw, Brigade Leader Lethbridge-Stewart, references alt!Jo
Summary: Miles below the earth, in the most secret and heavily guarded of all their prisons, they keep a man who builds them weapons that are decades and sometimes centuries ahead of their time. Reports come back of the things they bring him: books, chemicals, lab equipment. Young girls.
Notes: An AU for the Inferno-verse, which I guess makes it an AU of an AU. Basically, the Doctor we know never popped in from our universe, but their version of the Doctor has been their prisoner for as long as he has been in exile. Oh, and the world never burned up, obviously.
Warnings: Descriptions of torture (including allusions to sexual assault). A friendship with occasional Stockholm Syndrome overtones. Stockholm Syndrome.
