> I think Lupin knows its Snape's curse. His statement about Snape being famous for it implies some history there. So I would think that Lupin has seen Snape cast it in the past and has seen someone do some amount of healing on the resulting cuts. In fact, in the manner in which Lupin raises the subject, it almost sounds as if Snape invented this and tried it out at school on someone. <snip>

carol responds:
Sorry to be unclear. I meant that Lupin doesn't know that Snape has invented a countercurse, so he assumes that no one can cure it. after all, he's not present when Snape heals Draco. As for all the problems involved in Lupin's saying that Sectumsempra was Snape's signature spell when he didn't even know that Snape was a DE, I've already made those points several times and don't want to go there again. 

I agree with the part I snipped about James and Sirius being the "enemies" that it was invented for. I'm not sure about the amount of control; he was aiming for the DE's hand, which I assume he intended to sever as he severed George's ear (the DE must have heard the first part of the curse and swerved to avoid it).

Carol, no pun on "sever us" intended
