Harry's second year has not turned out the way he wanted. Everybody hates him because he can talk to snakes, and Lockeheart has gone all weird on him, so weird that Harry begins to fear what it's all about. He has no one to turn to, no one but Snape.

This is based on the riveting death scene in the sixth movie. It was so much better then the book and Alan Rickman is just an amazing actor. Snape's impressions of the situation when he is standing face to face with Dumbledore on the tower.
