Germane to the Head

The first bust lost its nose and had another nose affixed to it.

Or, rather, the nose of a second bust lost its face and so was affixed to the face of the first bust.

Therefore there is both a nose without its face and a face without its nose somewhere in the world, and no matter how much each piece longs for it, they will never again be reunited.

Additionally, there is a nose and a face that will be wedded together for all of time, whether they like it or not.
