Yes, yes, yes! That's how the scene should have played out! Loved Severus destroying the Horcurx, and wielding Gryffindor's sword, too! And, wow, that was intense, Harry and Severus staring at each other. Warmed me up as well. ^-^
Lovley fic, makes me hope that other certain scenes in DH will end up AU - and better for that - as well.
