"The brain is- it's complicated, yes, yes. Oh a little basic lobotomy is nothing, but the synapses are complicated. Hemispheres? No, no hemispheres are nonsense. Left brain, right brain, there is one brain, perfectly symmetrical."
"But that is the thing, that everyone's symmetry, nurse, is different. I have opened up many a cadaver, everyone has something unique to them. So, most brains, work almost the same. Highblood, lowblood, most processes are similar. There are, of course, differences for mutation by bloodline, or psionic potential."
"Now- Now psychic nullifers have to- they target the same area of the brain, that is a constant. But they don't really reduce the power of the- the power, yes. It merely lowers the output after it is already created. But a brain is, it's the, you know nurse, it's the factory that makes the power. To fix the power truly, you have to cut a few power lines."
"Anyway, the point tonight, nurse, is that we have to find where they bury the right power lines. You can't dig up the yard, no no. Too much damage to the property, you know. Cut the wrong parts out, there goes the ability to chew properly, or complex mathematics, or basic muscle control..."
"No, we will- I will just burn out- just disable the right power lines. A brain, you see, will heal itself. Most people assume brain damage is permanent, but it is a robust creation. Trolls are harder to kill than anyone might think. I have to burn it, cauterize it. Make sure the cells are dead and stay that way."
"So. I will now commence prepatory operation number, ah... Nurse? Right, number fifteen. Subject is a hiking redblood, sedated. Appears roughly nine sweeps of age, displayed talent for plant control... had to inflict one GSW to the legs to temporarily disable- Got lucky, missed the artery. One inch to the right, would have been a waste. Good practice for plugging a hole, though..."
"Now, where did I put that saw? ...It's sterilized. Okay, I need to focus. Voice recorder, uh, turn off, turn off..."
