After about ten rounds of brain injections a yellowy fatty substance begins to grow on the surface of the skull.
After about fourteen injections, the mandible starts to drop open.
A low guttural sound emanates from within, increasing in volume until it transforms into a wide open howl, then finally a scream.
The skull is alive.
It can inform us of how and why it died.
But for now it is coping with the pain of being severed from the body, and the pain of dying and being revived in a horrific form: no eyes, blood or skin, only a voice and a mind, and yellow fat around the perimeter/rim.
It will be killed again after giving us information we want.
