It occurs to me that there should be some new Inhumans who know exactly what is happening to them. Most of the inhabitants of Afterlife knew all about their heritage but hadn't been exposed to terrigen yet, and likely never would would have under normal circumstances.

Likely lots of others who will recognize this for what it is.
The numbers are not large enough yet for the Raina's of the world who want their destiny to pierce SHIELD's and the ATCU's security to know about the cocoons and it was the fish oil and then to start eating a seafood heavy diet. Since the emergence of the Hulk there have been other weird things happening
