Professor Snape was sitting in a low armchair, and he looked around as the class filed in.

Neville looked around rather wildly, as though begging someone to help him, then said, in barely more than a whisper, "Professor Snape."

"Professor Snape has very kindly concocted a potion for me," he said.

I am very lucky to be working alongside Professor Snape; there aren't many wizards who are up to making it.

Professor Snape's very interested in the Dark Arts, he blurted out.

"Did you tell Professor Snape we haven't covered them yet?"

The potion that Professor Snape has been making for me is a very recent discovery.

Professor Snape was at school with us.

You must see that Professor Snape's version of events is far more convincing than yours.

Say what you will about Professor Snape, but the man who portrays him is nothing short of amazing.
