It's a bit longer and it's also in Severus's point-of-view. I think this is more in tuned to Severus's character.

"The Shrieking Shack"

I woke up with a pounding headache. 'What happened?' One look at my surroundings reminded me. 'Ah, yes. Black, Lupin, and the Gryffindor Wonder Trio. The Potter boy is going to get expelled.' I gasped my wand (which was still in my hand) and pushed the debris off of me, noting the numerous cuts I received as a result of Potter's actions. I descended the stairs and peeked out the not-so-secret entrance into the Shrieking Shack. There was Potter with his two sidekicks, Weasley and Granger. He was so much like his father right down to the friends who never left his side. My blood boiled at the sight of the three of them. I practically leapt out and grabbed Potter's shoulders, giving the boy a shake.

"There you are, Potter!" I sneered at him. All three of them were staring wide-eyed behind me. I recognized that look. They were panic-stricken. So much so that they didn't give me more than a glance. Then, a familiar noise came from about five or six feet behind me. A very familiar noise. I turned around quickly and was "face-to-face" with an image from my past. Lupin had already transformed! I pushed the Trio behind me. 'No one's going to go through what I went through. Not if I have anything to say about it.' The images and emotions of the attempt on my life all came rushing back to me. Lupin the Werewolf snarled at me. 'Heh, I think he knows I was the boy who almost became kin or maybe he smells the fear.' All of a sudden, a great black shadow attacked Lupin the Werewolf. 'Wait a minute. That's not a shadow! That's Black!' My eyes narrowed at the dog. 'Trying to be heroic, Black? Well, it's only an act.'

Then, Lupin the Werewolf threw Black aside and bounded over to continue his assault.

"Sirius!" Potter cried. It was at that moment that Potter escaped my hold and took off after the werewolf and the dog. Granger tied to rush after him, but I caught her arms.

"Come back here, Potter!" I yelled at him. Whether he heard me or not, I don't know. Either way, Weasley and Granger were still near me. "C'mon. Follow me."

"But, Professor, Ron is injured!"

I rolled my eyes, but conjured a stretcher anyway. I lifted Weasley up and carefully placed him on the stretcher. I took off at a fast pace with the stretcher floating behind me and Granger had to run just to keep up with me. Just then, the air got cold. There were several dementors closing in on us. I whipped out my wand and pointed it at them.

"EXPECTO PATRONUM!" A silver panther leapt from the tip of my wand and charged at the dementors, chasing them off. Instead of disappearing when its task was done, the panther ran along side me.

"Professor…your patronus…why…is it in the…form of…panther?" Granger was out of breath.

"I thought you were a know-it-all, Ms. Granger," I sneered at her.

"Well…I…uh…"

'Oh, how I love frustrating people, especially students. It's so easy and a lot of fun.'

"That was a pretty powerful memory, Professor." Granger changed the subject. "What was it?"

"That, Ms. Granger, is none of your business. Five points from Gryffindor for being impertinent.'

Even though she was an impertinent know-it-all Gryffindor, she reminded me of someone…me.

Ruby-Moon Snape: I like this one a lot more than chapter one.

Severus: As do I, but NOW you have me empathizing with Granger!

Ruby-Moon Snape: And?

Severus: Five point from…

Ruby-Moon Snape: Ha, can't take points off your own house, now can you?
