Well, in the same conversation, Vic mentions that we've probably got a few weeks at best, but by the end, thanks to Alt, we've got an approximate six months, which is a vast improvement. That says to me that she was able to stop the degradation, but the damage to V's body is already done. That's why i wondered that, if possible, a full body conversion would work. The brain, as it is by endgame, isn't compatible with the body anymore, so if we could, why not change out the body?
As I understood it 2 weeks was the estimated time interval for the Relic overwrite process to complete. The time it would take for the Relic to purge V's consciousness and replace it with Johnny's engram.
The 6 month issue is another matter entirely.
In the Devil it's clear cut. The chip was integrated with V's brain. Arasaka had the expertise and equipment to remove it. Unfortunately the incidental damage is too much and V's body begins to progressively fail. Assuming the information they're feeding V is reliable.
My interpretation of the plan in the Sun/Star was to access Mikoshi, have Alt Soulkill V, separate Johnny out and re-input V into the chip as a digital construct. The problem is V's body cannot handle the stress incurred from all of this abuse. The plan works but the body begins to progressively deteriorate.
I assumed the commentary involving DNA and immune responses was meant as an analogy. Not something to be taken literally.
The word body here is likely being used as an umbrella term to describe the physical brain itself, the way the connections are formed within it, the balance of various hormones, neurotransmitters, etc. The brain itself is a part of that equation. It's one of the damaged and/or failing areas. It's reasonable to assume those problems would remain if it was relocated elsewhere.
It's not from me at all. It's the result of the scanner in the penthouse during the BD or in the tower if you take time to scan him
Adam Smasher
It was a weak attempt at a joke. Supposedly on average the brain accounts for ~2% of the total weight of a person. If Smasher replaced everything except the brain and 4% of his original form remained it implies his brain constituted ~4% of his total weight. More or less depending on the relative weight of the replacement parts making him tinman and any left-over skull/skin of his bald, shiny head.
Smasher never stuck me as a big brained individual. I suppose it's possible it was an elaborate ruse to feign ignorance while keeping his epic intellectual prowess in his back pocket. He certainly had a knack for showing up out of nowhere and catching the other characters flat footed.
