On Day Zero, Damian felt perfectly fine and was getting ready to start his day.
He entered the bathroom just as his sister who had been sick for the past couple days coughed near the sink and left.
What he didn't know was that there were hundreds of bacteria floating around from when his sister coughed and they managed to make their way inside his mouth.
The body's skin was useless against the antigen as it came through the mouth so the body began to produce mucus, tears, and saliva to fight it off but was also practically useless, but the body's second line attempted to go to work on the bacteria.
But the white blood cells were no use, it turns out this antigen was a tricky one and was on its way to the central nervous system, it was on its way to becoming meningitis.
The antigen had begun to take a toll on Damian and his body as it began inflammation of the mengines and brought him sleepiness, lathargy, and fever over time
But once it got detected by the helper T cells and antibodies, the killer T cells were able to locate and hunt down the foreign antigen.
