Purifier creator commentary pg.74 (Patreon)

Believe it or not, this mobile flamethrower is not my invention. I found a photograph of it being used after the war to sterilize a chemical weapons factory and felt it was too incredible to not use.I fret that I may have not emphasized that the risk of contamination in the crime scene house, but that's what's going on here. Too many people living in too close proximity makes for a dreadful breeding ground, which I'd hoped to infer was the real ground zero for the evacuation that took place in chapter four.
