Welcome to my new reader...but why did you post the same thing twice? Yeah I'm from Greece, nice to know there's someone else from my country reading this story...
Welcome back to Tori too. Oh, and I'm sure many Death Eaters knew Sectumsempra, they must have seen Snape casting it millions of times when he was a real Death Eater. Anyway, I think I'll post later today so stay tuned.
