In Vino Veritas
Characters: Tamsin and Dyson, post 3x04.
Tamsin and Dyson go drinking.
They're thrown out of one bar, then two, and by the third Dyson is loose enough for Tamsin to take him to their true destination. A place where light and dark meet, nowhere so polite as a ritual battle-site or a waystation. A place for forbidden trysts in shadowed corners, for trading artifacts of the light for the pleasure of the dark and vice versa. Where the lines cross and blur until only gray fae remain.
Dyson's fun when he's not moping about Bo. Somehow, Tamsin can't pretend to disinterest as he talks about her.
