Sorry, I don't follow the drek on Twitter, and If Dakken returns in All-New Wolverine, then that book will surely fall in sales totals and the writer should be fired so don't count on Marvel approving the "return" button on "worse Wolverine". Marvel knows he sucks, and why after Secret Wars and the Wolverines they shelved him like DC did Emo Lobo who strikes an odd resemblance to Dakken as far as being a pu you know what.
We knew Sinister was a thing with the end credits of Apocalypse.
And if you have 4 posts, claiming appearances and things with no credibility, it might be someone trolling on a 2nd account.
