I can't believe I am putting this out here BUT
how many of our FF school shooters have the MAO-A gene?
I'm rewatching old blacklist episodes and happen to be watching one that talks about manipulating people with this gene in therapy and turning them into a weapon. … i know…
However, its called the WARRIOR gene for a reason. What if???
