'And here we have six missing Death Eaters ... Three dead in my service. One, too cowardly to return ... he will pay. One, who i believe has left me forever ... he will be killed of course ... and one, who remains my most faithful servant, and who has already re-entered my service
The first is Karakaroff, the last is Crouch, so the second must be Snape. So if that is the case does anyone reckon that he will have gone back to Voldermort, as i have thought for quite a while.
I mean if he is there to spy for DD, then in order to convince V that he is back on his side he must therefore pass on some information about what people are doing against him. He wouldn't be able to pretend that he didn't know anything cause he's a teacher at Hogwarts, he sees DD everyday, he couldn't know nothing.
So i do wonder what exactly it is that he's doing?!
