OMG. How did I miss this? I've read most everything. This one just... slipped through the cracks. *headdesk*
If I HAD read it when I didn't know it was you, I'd still have guessed just from that last bit. The public-ish sex and kilts gave you away. ;D
I really enjoyed this, love. Harry's confusion about what Kingsley was talking about, and then Snape's reaction. And the whole tracking via the Dark Mark was a fun twist. Very nice!
