A prompt for anyone who wants it:

Marathon/Doctor Who fusion of some sort. Bonus points if you can work in a reference to Sapphire and Steel. (Ideally I'd also use an OC Doctor for this to relieve at least a little canon baggage on DW's side, if that makes sense, but I'unno if everyone reading this would go that route...)

This post brought to you by fatigue and remembering that Leela the AI was named after Leela the companion, per Greg Kirkpatrick. Oh, and this old, massive DW slash fic I found on Slash City that does the OC Doctor thing mentioned above and brings in both The Tomorrow People and Dark Shadows. Too bad the formatting in Chapter 1 makes my brain glaze over...
