Imagine your body being taken over from the inside out, cell by cell, neuron by neuron, synapse by synapse.
Your body possessed, transformed, but from the outside, still looking normal, too normal!
The 'Big Bang,' the spark, the singularity, call it what you will, 'kick-started' David's new brain.
David had a new consciousness level where our anthropic reasoning did not exist other than as a vague blueprint of eccentric thought patterns, verging on the self's paranoia.
A set of charged ionic-nerve impulses, produced from a biological matrix, extrapolated into a fragile electro-biological storage mass for future reference.
To the 'new' David, our laws of creation were now redundant.
