Possible Carrier.
Such an innocuous name for something so ominous
A foreign defect forever in your genes
It's scary to think one mutation could be this ruinous
A hidden little fiend that tries its hardest to go unseen.
Expected Carrier.
Am I of the aforementioned category?
Will I have to worry about carrying something to a future child?
Why me? I'm sure they all ask when they become it's adversary
The probable anomaly in my blood, so heinous, so wild
Certain Carrier.
In the deep, microscopic DNA you lurk
Waiting for the chance to take another host
Go from being only half, to a full-blooded curse
Carried through generations an aspect you gloat.
