I like how this opens with Snape musing on the war and very important things. It gets us into his head but also does a good job showing what timeframe we are actually in. It also builds Snape's character. I liked that he looked around when he entered the Headmaster's office. I really liked this line: "Granted, if you decide not to, we will have to act quickly and seriously in our attempt to sever your connection to him through the mark, lest we find you dead from it.” It's very direct, but realistic (and dramatic for us).

Your Dumbledore, to me is a little hidden. I can't tell if he really wants Snape to stop spying becasue he cares about him, or if he's putting on a very good act and doesn't expect, or want Snape to stop spying becasue of the war. It's very intruiging and I hope that I will get to figure it out in later chapters. :)

I don't like how many times Dumbledore said "My boy." He said it four or five times. it started to be too noticable.
