Sanguinity has just reminded me, though, that she loves epistolary fic and is currently enrolled in an exchange focused on fics that tell their stories through letters or diary entries...maybe writing "Taste" revived her (wait for it) taste for that genre and inspired her to write more for her other fandoms in that style? Your guess is looking better and better, I think...

Also, as long as I'm diving back into the guessing post: I think maybe Love As Fearful Torment might be Garonne's.
