Prompt: 32, Dark!Harry -- The Wizarding world might still be blind to it - for now - but Severus could see the darkness brewing in Harry from miles away. And he always was drawn to dark magic...
Summary: Harry thought he was entitled to use an Unforgivable Curse here or there. After all, he was an Auror. But someone familiar, someone he missed, seemed to know exactly what he was up to.
A/N: Harry doesn't stay very dark for very long, sorry! Thanks so much to writcraft for beta!
