Coffee by JackVelvet is a fic I read back in the day at the height of the Nolanverse Batman craze. I was obsessed with the pairing Jonathan Crane/Bruce Wayne (aka Scarecrow/Batman), which was, unsurprisingly, a rare pairing. It is just like me to get hooked on a pairing almost no one is writing about. And when I did find any Wayne/Crane fic, a lot of it was just smut. No lengthy fic, no plot, no character development; it was boring. There were maybe two other lengthy, well-written Wayne/Crane fics out there, and I had already read them both. And then, dearest JackVelvet (admittedly a friend of mine from my LiveJournal days) wrote Coffee, and blew me away.
Not only is this pairing a rare one, but both Batman and Scarecrow hate each other. And while many fanfic authors would idly brush that hatred aside in favor of sex and romance, JackVelvet takes the time to build a believable setting in which these two characters would grow to fall in love with each other.
