In KJSE, we never actually saw him DIE. Sure, his heart stopped–we heard the flatline. But that doesn’t always mean it’s the end. Lemme drop some medical knowledge.
When the heart stops, that’s a Code Blue, which basically means that a team of doctors immediately start chest compressions to oxygenate the body again. However, the longer the brain goes without oxygen, the more damaged it gets. Usually around the ten minute mark, there’s a good chance the patient will suffer permanent brain damage after being revived.
There’s a very good chance that when Jack’s heart started again, his brain was so damaged that remained in a coma in the hospital. That might explain why Jack is seemingly “stuck inside is own head” with Anti–Anti is still inside of him, but his body is too damaged to sustain itself apart from the machine that’s supporting him.
It also might explain the bleeding and raspy breath–it’s very common for doctors to break ribs during chest compressions.
So, I was doing a bit of research a few minutes ago on possible reasons why eyes may bleed, and if it has anything to do with head injury. And while I was only able to find that eyes bleeding could be caused by infections like pinkeye (or happen just because), I DID find this:
(TBI stands for traumatic brain injury)
Now, I’m sure we can recognize some of these symptoms in Jack, as well as mood swings, which were addressed in KJSE.
Whatever Anti did to Jack, it gave him a brain injury. Which makes sense. Anti could easily infect Jack and adapt to his brain, then manipulate his electrical signals, being a glitch and all. I don’t know if it’s possible to “fry” these signals, per se, and cause the brain to overload and attack itself, but I’d wager anything’s on the table at this point, given what exactly we’re dealing with here.
