Not to be confused with the Enlarging Ear Syndrome. Victims of EES include Will Smith and Christopher Eccleston.
The "Disappearing Ear Syndrome" (DES) is a rare and mysterious disease inherited by (and only by) the Slender Family. While the disease is harmless and non-contagious, the symptoms (caused by the immune system) cause the ears to turn invisible. Evolved versions of the virus, the one inherited by the Slender Family, has made other facial features disappear.
The disappearance of the ears is noticeably distressful for others who are not familiar with the disease.
