Draco felt as though he had been tossed headfirst into the Black Lake in the middle of winter. Everything in him froze: his legs, his blood, his lungs. His terror was so complete, so all consuming, that he didn't hear much of what passed between Narcissa and Hermione. He could only watch the two people he loved most in this world speak rapid fire at each other for a few seconds before Narcissa turned to him. "Draco, sweetheart. Walls up, right now. You must protect yourself. And you must protect Hermione. We have minutes. I'll give you a moment, to say goodbye, but she has to go, right now."
