I have a feeling Iso might be left in charge of New Attilan, Medusa seems to be grooming her for a leadership position. She's definitely showing what she is made of in this event.
I don't understand this?
To everyone who isn't the X-Men, the mutants are randomly attacking the Inhumans for no reason. Why wouldn't Kamala help the Inhumans who are being attacked? Moon Girl is rather iffy but Kamala would definitely become involved.
I imagine this will change when they learn about the deadline, but typical X-Men, didn't tell anyone because it'd probably have negated the need for all this violence.
It does matter quite a bit actually.
Everything in IVX could still have happened, then the X-Men released the Inhumans and say "we had to keep you occupied while we drained the terrigen from the atmosphere to save our people, here is said terrigen, we know you weren't too happy with it being a cloud to begin with. The war is over, everyone is happy, no need to go to space to fix our war provoking recklessness. the end"
Instead their plan is destroying the cloud, release the Inhumans and say what? "Oops. Bye" Sure, that's not going to cause retaliation.
The X-Men had the perfect way to end this conflict and satisfy all parties, instead they decided to also make the machine destroy the cloud.
