Hermione knew that she shouldn't have been surprised that Draco gave the horrible man lessons in tracking. Though she still didn't entirely understand the wizard's role with the Resistance, it was evident that he'd spent years working with them in some capacity.

She'd been responsible for ending the lives of countless others. What was one more?
