even if he and Chloe choose to simply run away like that, I bet the witches won't easily let them go
there's also the matter with the humans, too... as far as they're concerned, every witch is their enemy, which means MC and Chloe will, again, live in hiding
edited to add:
I really wonder why the witches chose such a tasking method to fight the humans
aren't the humans already at risk from the radiation and such?
