I loved the issue, but also have a hard time with some of the plot contrivances.
Firstly, it is absolutely ridiculous that Forge can now create black hole bombs. That's the kind of thing where once you put that out there, it's hard to take back. He should literally now be making them over and over again and they should be constantly dropping them on Orchis until they get it right.
Second, Mystique waiting around to deploy it is a problem. They should have had her note that she miscalculated or something and was too curious about what they were up to and waited too long.
But overall, I love that they planted the seed looooooong ago of Mystique being an issue for the future of Krakoa and now it's maturing. She was part of the original Orchis mission in HoX and this slow burn of a plot detail is going to explode now!
