It's complicated.
Claremont fought to bring her back in 1986? No, he wanted her to stay dead. And he wasn't ordered to kill her. It was hs and Byrne's idea to kill her. Oh, not from the start. But when Shooter nixed their original story, printed in PHOENIX THE UNTOLD STORY, he wanted her punished for eternity on some prison planet. They said, screw that, we'd rather kill her.
I just finished re-reading the Morrison run last night. I wanted to do that before I posted in this thread because honestly I didn't remember much in exact detail. Having read it fresh I would say that Scott and Jean were both heading in different directions the way they were written, I don't think they were "over" each other, but they both made passes at other people (Emma and Logan) so to me the relationship was cracking. That however is part of marriage, some couples work through it, some ignore it and resent each other and some break up/cheat. I think they still loved each other and could have worked through their issues, but that's not the road Morrison wanted to explore. I voted "it's complicated."
Exactly. It's set up to be a tragic outcome because they lost the chance to work it out when the probably could have.
But now they have a chance. Comics being comics where death is not permanent, I expect that even if Morrison killed Jean without any editorial interference, he expected her to be brought back eventually. He would not establish something like the Phoenix Egg otherwise.
Scott loved Jean throughout the run. He was in a deep depression, not handling it well, and his stating he felt his marriage was a sham while in this state does not have to be taken at face value. He realized too late what he was losing as she died, as Logan basically said he would a few issues earlier. It was very complicated and human.
