I find it hilarious how many people have their PoVs skewed by their own bias and fanboi love of the X-Men.
The Inhumans aren't villains and they certainly aren't unsympathetic to the Mutant Cause. Medusa sent Crystal's team out ahead of the clouds to clear the areas of civilians who didn't want to be changed by the mists, and when it was found out that the cloud caused the M-Pox they immediately amended their plans to remove Mutants from the areas ahead of the cloud to SAVE them.
The only true villain here is Emma as she single-handedly declared war on the Inhumans for "reasons".
I understand people are upset about the Mutant Mandate and not happy with Inhumans being pushed as the new big group but don't use that issue to start causing issues elsewhere and misrepresenting the issues actually being written in these books.
