...I felt the vibration of noise. No doubt the human was screaming. But I pushed on. My forward antenna array felt the darkness, the warmth, the welcome confinement ahead. Down into the unfamiliar tunnel. I was an explorer! To the best of my knowledge no other Yeerk had ever gone where I was going: into a human. The first, I would be the first human-Controller. My place in history was assured...

...But this was all new. No one could tell me what to expect. No one could tell me what I would find inside this new, unexplored territory, the human brain. The ear canal was too tight, of course. There were structures in my path, small bones, a sort of timpanic membrane. I experimented with shoving them aside, rearranging them, secreting the numbing chemicals as I went. And then, at last, there it was! Just an inch away. Nothing but a last flimsy membrane between me and the brain...

...Flashes of auditory memory. Had to be, it wasn't real time. No, definitely memory. Memory of human voices. Several different ones. Meaningless jabber. I wasn't near the language circuitry, yet. I spread, squeezed between skull and brain. I found deep crevices, cracks, gaps within the brain. Experimentally I reached down into one of these gaps. There! There it was: language...

...I continued my exploration. And then, suddenly, I was seeing. Seeing with eyes that were very similar to Hork-Bajir eyes. Weaker in depth perception. Stronger in color differentiation. Slow to adjust form long distance to short. But good eyes. Eyes that would serve a Class-Five species...

...Then I discovered something strange and disturbing. A huge, deep chasm. It seemed to separate the human brain into two halves...Why? Why would the human brain be divided in halves? It was irrational design. It made no sense...This brain worked by dialectic. Each half of the brain saw and heard and smelled and touched a slightly different world...Confusion! Disorder! Illogic! This mind could argue with itself...This brain contained its own traitor! And, as I began to sift the memories I saw, again and again, the internal argument. The "Should I? Should I not?" debates. The paralysis of internal disagreement...No wonder they kill each other, I thought. They very nearly kill themselves! It was madness. Humans, as a species, were mad...
