Facial injuries! It was the face that had disappeared fifteen years ago, not the man. Westing had a different face, a face remodeled by plastic surgery. A different face and a different name. (22.44)
How do you define yourself – -by how you look, or what your name is? And how do you define other people? It's fairly common to identify people by their faces. Westing's turned all that upside down, though, by remodeling his face and name and, in doing so, creating a new identity. As the judge observes here, "the man" isn't who "disappeared" – only his face vanished. She thinks "the man" is still the same.
