Ouuu, wow. You really, really managed to capture Harry's hatred for Snape and Snape's for Harry. Like this line, that I loved: "Maybe he was ill…or maybe he was dead? Harry grimly suppressed a smile as he envisioned Snape slumped over his desk, his black, greasy hair falling across his face, as the headline of the Daily Prophet read, “Death Eater found Dead at Hogwarts." Wow. You got it. I loved your characterization of Snape in this chapter, how human he was for a moment, but how he really is that cruel evil Professor. You are so in character with him! Amazing tension and bantering. Poor Harry, Snape's words are there to really wound.

I still think that the Trio should go to Dumbledore though. I wonder where Snape was before? I think that there are a few things you can do to make you story better: one of them is to correct the few typos that there are. In this chapter there was a "clamed" instead of "calmed" and there were some in chapter one too. You also need to spend a little more development in Ron and Hermione and Harry's interactions together. Harry seems a little off with them.
