I loved this chapter. And I love that little backstory of Severus and Charity... it was something that struck me in the first chapter, why this woman would call him by his first name... by that time all of the teachers would have know Severus killed Albus, yet this woman thought of begging this supposed "traitor".
I loved also how mature David seems sometimes even if you can see he's still a child. Also how protective Severus is.
