Man, Charlotte feels ya tho, she was very tempted to drop Nate like a hot potato once she heard all that science talk
and not to mention that neck bite, swoon, BUT NO, JUSTICE MUST PREVAIL NO MATTER HOW HOT THE VILLAIN IS TO HER.
Offhand, I still wish to speculate @mewsly’s last point:
What exactly did Murphy plan to use the Detective for?
As she said, it’d be very…unlikely if he wanted to storm the Agency by himself. Sure, he was able to hold off Unit B with the Detective’s blood, but, a whole Agency? Seems kinda…dumb for our methodical maniac.
No…I think that Murphy was actually planning on maybe harvesting blood from the MC to have a small horde of his own, and then flooding the supernatural world (specifically the kind that’s not directly associated with the Agency) to cause more supernatural crime. Then, as the Agency becomes thinned out from all the work they’re under, and perhaps even some Agents become addicted to this new substance on the streets, and manages to break out some inmates, maybe the most dangerous. Eventually, the Agency would be taxed beyond its limit and all that would be left is a giant turf war with humans caught in the middle…
All the while, Murphy and the Detective have remained anonymous, constantly moving, never staying in one place for too long. Then, when Murphy sees that Earth has been irrevocably changed…he pulls the supply. Lets the other kings of the mountains bleed themselves dry as they try and maintain order…and then Murphy swoops in, and then I don’t know.
