All endings involving Mikoshi don't make sense if you really think about it. So, V and Johnny are separated, both are digitized engrams, and V can be reinserted into the body and die in 6 months, or they can let Johnny have it with a regular life span. Alt says the body has been changed so much, even on a genetic level, that it will reject V. There are problems with that:
1. Both V and Johnny are digital engrams, so why does the body care which piece of digital code is being added back in the brain chip?
2. Even if your DNA can care about what piece of digital code gets inserted into your brain chip, why can't the same nanite process that changed V's body in favor of Johnny be used to change the body again in favor of V?
I think the choice is an interesting one narratively, but the way it arrives at these options kind of falls apart, at least for me, when I think about it for more than 5 seconds.
