Amazing Spider-Man goes full on with making Ben the villain of Dark Web, complete with Janine turning on Maddie and getting her Scythe and handing it (and control over Limbo) to Ben. Granted, Maddie's a bit a dick in that she doesn't get the X-Men to help Ben with his problems, but given the shit given to her over the decades, I can forgive her and Wells for not dog piling on her. But still, Ben goes super saiyan and becomes "King Chasm" and everyone gathers to beat up Ben, even Rek-Rap, who again seems to be Wells chasing after that movie royalty dollar money with his own silly Spider-Man stand-in.
Meanwhile Sins of Sinister has Gillen shit all over all of the good will he's built up by taking the idea of an out existing for undoing the Nazification of the X-Men in the Krakoa era and crapping all over it to close off the loophole from being used as part of a reset down the line.
Sinister reveals that since day one of Krakoa, he tainted his DNA library of every known mutant with a bit of his own essences, so that when someone dies, they'll come back "Sinister-ized" with a red diamond on their foreheads as an evil version of themselves
Interesting out for SOME character derailment being undone? Well Gillen shuts the door on it by revealing that Hope fucked all those plans up since every time someone got resurrected, Hope as part of her role in the resurrection "circuit" unknowingly purged Sinister's taint from every mutant that came back.
So the events of #9-10 was part of a long con to kill Hope, plus Emma and Xavier and Exodus (IE the big time psychics) in one fell swoop to ensure that Hope came back via alternate means (IE Synch not being able to debug shit like Hope did for reasons) with the Sinister taint intact. And from her, all of the other resurrections too.
(Oh and Sinister has a new grand scheme: turn Earth/mutantkind into a Dominion type hivemind so they don't get consumed by the Phalanx Dominion hivemind first)
As such, you now have evil Xavier and Emma and Hope and Exodus doing all sorts of evil shit over several years, slowly growing their ranks until they lobotomize Krakoa itself (and killing Cypher) and blaming ORCHIS, with the Avengers being the missing ingredient to shut down the Forge and Nimrod once and for all. And them infecting humans with tainted X-Genes to turn them into Sinister-lites too. But that by the time they free Sinister from the pit (and drive Storm, the last X-Man untainted by Sinister into hiding after blowing up Mars) the now tainted Quiet Council, having conquered the Earth, decide to conquer the galaxy over Sinister's objections. And Sinister finding his save scumming machine having gone missing so he can't revert back knowing that his plan failed due to his tainted X-Men being beyond his control.
