From illereyn:

Can we hear about Sherlock-Bondlock, Sherlock-Wings, and because I haven’t read fanfic for it in a while – Doctor Who – Marriage? Yes, I am greedy and insatiable for your writing!

Ah, the Bondlock is a mistake.  That is not a WIP; I actually wrote and posted that to Tumblr a while back.  You can find it here: http://prettyarbitrary.tumblr.com/post/42334092804/a-bit-of-bondlock

Wings is another of those where I stowed the prompt in a doc and planned to do something with it but never quite did.  Here’s the prompt: “I don’t know if your wings are real/but I’ve never seen you without them/and I follow you everywhere—John always sees Sherlock with wings, but no one else, including Sherlock, seems to know they’re there.”

Doctor Who-Marriage, though.  Oh man, I love this one.  It also started with a prompt, but the idea…woosh.  I will share the kernel I started with, and I am sad that I never managed to expand and dig into the nuances the way I wanted to, because I loooooooove Time Lord world-building (as far as I’m concerned, Moffat’s primary offence is lack of imagination; he could do anything with the Time Lords, but instead he just makes the Doctor act increasingly human and starts introducing rules about what you CAN’T do when you travel in time):

For a thousand generations, since before the time of Rassilon, Time Lords have been forbidden to love.

They get on well enough without it.  Marriages were socially motivated affairs, arranged to produce political alliances and unions both genetic and scholarly.  The Time Lords in fact congratulated themselves on the efficient civilization thus constructed.  They grew complacent, pragmatic and passionless.  So passionless, in fact, that by the Doctor’s time, the Time Lords have forgotten why the proscription was ever important.

The Doctor and the Master remind them.  The laws of reality itself are not proof against a Time Lord’s passion.
