Literally how many times has Xavier come back from the dead? Is that really necessary again?
I'm sure we'll see them interact soon enough. What should they 'confront' each other about? Jean personally encouraged him to move on from beyond the grave. With her last breath she also told him to live without her.Emma/Jean/Scott's confrontation?
Again: There is no reason Logan, Emma and Mystique would battle to the death after the last run.Logan/Emma/Mystique death battle? Rest of team seeing the person they decried as Mutant Hitler, and the woman they threw under the bus afterwards? Jean suddenly being suicidally meek?
At the end of the last run all of those mutants were literally shown on-panel together united (albeit with poor writing from Rosenberg) against humanity. That is the cue for the time jump Hickman then instituted. You feel that's all invalid, and that they should've all attacked these characters unfairly bc that's what you feel the X-office does. But your personal opinion doesn't make it a fact or something they must now explore. The end of Rosenberg's run chose to rush past and dispense with all of that. Bad book? Yes. But that state of affairs you wanted to exist at the end of Uncanny didn't exist at the end of Uncanny, and won't now. That's not Hickman's problem and it's not something anyone should be expected to write to just because you're pissed and want them to re-litigate the last 5-10 shitty years of comics.
And Jean was not "suicidally meek". She was in a no-win situation where everyone else had died and she was injured and battered in a tiny escape pod in the vacuum of space surrounded by Sentinels. Outside of fanfic there have rarely been ways out for X-Men in that scenario, a non-Phoenix Jean included.
These are largely things you are demanding they address because of your personal take on what the X-Men books should be based on past sins. They are not relevant to anything Hickman is doing.
