But if the series is following the original blueprint of Chuck Hogan and Guillermo del Toro’s last book in The Strain series, The Night Eternal, that bomb is going to be used at the site of The Master’s “birth,” which is the only way to kill the vampiric bastard.
Of course, if Fet does get his hands on the nuclear weapon he’s on the hunt for, there’s still one person that could screw all of this up: Ephraim Goodweather.
It’s kind of interesting how a nuclear bomb triggered this whole mess at the end of season 3, and yet another such weapon is supposed to be the thing that’s going to save everyone.
