We open to that one scene in HoX/PoX, where Charles is chilling on a bench. Only this time, Moira shows up, bleeding from her gut. She says, "#$%& you, Charles." She says that she wishes she never met him, calls him a coward and traitor, and vanishes. In the present, she's refusing to die until her last breath.
Meanwhile, the Wolverine kids are fighting a gnarly-looking skeleton Omega Wolverine. Sage and Beast are observing and believe it's heading toward Cradle 4. Since it's a port, the Phalanx can corrupt it and get access to their biotech. Beast will work on disconnecting the cradle from the mainframe, while Sage will do something with a the Cerebro Sword.
Meanwhile, Omegaverine is fighting against the Phalanx, begging the kids to stop him before it's too late. Regular Wolverine shows up to help his kids. He holds up his stupid freaking stopwatch and spouts some lines about how someone gave it to him so that he'd never lose his way. He then makes a "your time is up" quip and fights Omega.
We get an info page about how various X-Men died in Omega Wolverine's future, but none of them are Hellion so it's not important.
Wolverine fights with Omega Wolverine some more, and he's doing a lot of narrating. Sage shows up with the Cerebro Sword. She programmed it with nanites meant to counterprogram the engineering of Wolverine's skeleton. Wolverine takes the sword and stabs Omega, killing it and the Phalanx. Krakoa absorbs the Phalanx-free bones into its butthole.
After this, Wolverine decides to drink. After yet more long narration, we cut to everyone hanging out at the Lagoon. Beast talks to Sage about how good and cool and amazing Wolverine is.
Ten days later, Robo-Moira comes back to life.
The Krakoan at the end reads WADE IN. But that's boring, so pretend it says HELLION and write to Marvel about getting him on a book.
It felt a little anticlimactic to me, but it was fine.
