Every broken mirror, pieced together after a fall, needs a rim of onlookers to hold the shards in place. Otherwise the pieces will fall into a jumbled pile and will never sort themselves out. Anyone who's tried to put a broken picture frame together again knows that you need a metal frame to hold the glass in. Even when the shards of a story are on the verge of making sense, they still need something around the rim to hold them all together. They need strength from the outside to discover the memories inside themselves.
