GINNY: After I came out of hospital — everyone ignored me, shut me out — other than, that is, the boy who had everything — who came across the Gryffindor common room and challenged me to a game of Exploding Snap. People think they know all there is to know about you, but the best bits of you are — have always been — heroic in really quiet ways. My point is — after this is over, just remember if you could that sometimes people — but particularly children — just want someone to play Exploding Snap with.
