The deluminator. It doesn’t just turn off lights. I don’t know how it worked but Christmas morning, I was sleeping in this little pub, keeping away from some Snatchers, and I heard it. A voice. Your voice, Hermione. You said my name. Just my name. Like a whisper. So I took it, clicked it and this tiny ball of light appeared. And I knew. It flew towards me, the ball of light, right through my chest and straight through me. Right here. [touches his heart] And I knew it was going to take me where I needed to go.
