I keep re-reading your Four/Romana/Sarah Jane as Four/Leela/Sarah Jane, and, er, now I sort of want that as well. (In the mild way only a wimpish shipper can...)

And more fic, like in your icon?

Sarah: Doctor, did you put that heart there?
Doctor: You mean you didn't?
Sarah. Aw, well. It's pretty.
Doctor: Don't touch it, Sarah! It's an evil, pink floating heart!
Sarah: I refuse to believe there's such a thing as an evil pink, floating heart.
Doctor: Then what's that, eh?

(Er. I think I'm not fully awake yet. I understood. Four/Sarah OTP, yes? ♥)
