Ha, I love this look at Aftermath; just where are you going and what do you seek? I think that sums up the motivation nicely, and you did very well to bring it out in your characters, especially Severus. Although he has eight limbs and no vocal chords for most of the story, his inner thoughts are very ... illuminating, while its nice to see that your Harry doesn't bumble about in the dark, and remembers he's a wizard with a good 'lumos'. The detail was quite nice, especial for sub characters like the Weasleys; the dialog between Arthur and Molly made me laugh, and Ginny was just the right bit of 16-year-old-fan-girl, a little too focused on 'me' in most of her speech to make her a viable choice for Harry, perfect tone.
