Unconventional Courtship

I'd like to sign up for August 4, since it seems that all days already have at least one person signed up anyway. I'm still trying to decide between several intriguing options for what to write, but I want to sign up to make sure I'll write at least something. The fandom will probably be either Torchwood (Jack/Ianto) or Doctor Who (possibly Thirteen/Missy, though there are other tempting things as well). If we get lucky, I might even manage to write more than one...
