How to Fix the Inhumans?

[Tofali]

Under Hickman the mists were released then faded into the atmosphere. They weren't consolidated into roaming clouds. They just became diluted into the ecosystem making anyone who could go through terrigenesis, go through terrigenesis all at once.

Hickman wasn't that specific and he didn't specifically say that the mist "faded into the atmosphere"

This was retconned by Soule/Marvel but in Infinity, it's pretty obvious this was how it was.

It was retconned in Uncanny Inhumans - IvX but it wasn't post Infinity - Inhuman.
