Yeah, so many People are getting way too worked up over this and are crying "But what about Hickman?"
Hickman's fine, he is going to have at least two more books under his wing plus his ideas for X-Men will influence things going forward.
I can't speak for him, and no one else can, and maybe in 10 years we'll get some information about what happened, but again, it sounds like he is okay.
People just follow cult status too much and get disappointed when things don't go their own way. And creators are not always right in what they say.
Twin Peaks is my favourite show of all time, but I will admit the idea of a mystery that lasts years will get old very quickly. That and the show's destruction lead to some of the best things ever put to screen.
Now Hickman will want to leave his run on a high note, so Inferno will just be that. And unlike the name implies, it doesn't look like he is burning bridges with Marvel.
