Holy fucking hell. I love you. Going for coherence here, bear with me.
The wand-how Harry thinks it's the wand driving him. The circumstances of Newlin's birth-dear god, what a mess and poor Narcissa. How totally fucked up Davies is, how it's really hard to say at what point Newlin really chooses which side he's on (so like dear Severus), the times when they talk about Snape-Newlin's reactions were priceless. And the end-oh lord, just perfect. Absolute win.
