So I'm re-reading Book 1, and I get to the feast after the Sorting, and read this:

... Professor Quirrell, in his absurd turban, was talking to a teacher with greasy black hair, a hooked nose, and sallow skin.

It happened very suddenly. The hook-nosed teacher looked past Quirrell's turban straight into Harry's eyes -- and a sharp, hot pain shot across the scar on Harry's forehead.

So the first time Harry sees Snape (and Snape sees Harry, presumably) their eyes meet... and the last time, as well.

Have to admire a writer who knows her plot, and her characters, that well.

I’m curious to know if Snape was an unregistered Animagus or did Hermione just not spill the beans.

I just finished re-reading that as well. When I got to that part this time, I thought that maybe the scar didn't hurt because of Snape, but because of the proximity to Quirrell and Voldy. But that Harry would think it was Snape.
