Potioncat:
My opinion falls somewhere between Sridhar's and Alla's. It's one 
reason I think Severus's Potions book went missing while he was a 
student. Although the timing doesn't work out correctly.

In the book Levicorpus is nvbl. So even if Severus used it, he wasn't 
saying it out loud. Either he taught someone who passed it on quite 
freely, or someone stole it.

As to who that someone might be, I cannot say.

Potioncat:
If I've never said it before, welcome. Before you know it, you'll 
have all the theories in your head and you'll be referring to them 
too. And like most of us, you'll probably know them so well, you'll 
have a hard time remembering where theory ends and canon begins. :-)

In GoF ch 30 during Karkaroff's trial, DD says that Snape "rejoined 
our side before LV's downfall and turned spy at great personal risk." 
So he had to turn in time to experience some danger and provide some 
information before the night LV showed up at GH. Weeks? Months? a 
year?

I suspect Snape was already working for DD when he overheard 
Trelawney.
