Hunter and Hunted-Death Eaters
Maybe I am wrong….but there is something that bothers me in the movie Goblet of Fire, but I have seen that never mentioned by anybody else….
Both Moody (yes I know he is an impostor but it is important for his cover, so…) and Barty Crouch sr. are former Hunters of Death Eaters. And not only out of duty, but on the edge to be fantatical to hunt them down. And I know, so do they, that Snape is cleared of charges by the testimonial of Albus. But he was a Death Eater ( no one stops to be a Death Eater)
Given their tendency to be a fanatic in that matter I would have expected more animosity between Snape and those two. It is pretty unlucky too, that those szenes between in Moody and Snape about Harrys Dragon egg are not in the movie, The behaviour of those two and Snape is almost friendly or at least professional.
