Oh, wow, this was fantastic. Great Neville voice. I loved this part:

He is unused to the uncertainty and doubt that lingers in her brown gaze, and knows that for all of her outward bravery, she too will need someone to be her rock during these trying times.

Because it's so true. Ginny comes off as so assertive and self-assured, but even she falters and gets scared. They both make each other stronger.
