I gave up trying to defend or invent excuses to defend the horrible things Marvel has done to the relationship between Jean and Scott from Morrison to Endsong. they are all true, that's the point, marvel was breaking their relationship and they did it that way. they have been over 14 years and counting.
I'm also tired and don't like to trash others ships (like jean/logan or scemma) anymore. there are reasons people like them
I just want to say that i like the relationship between Jean & Scott. when they aren't in a love triangle or jumping on other people like in the last decade but again it has been this way since their break up. When the relationship existed it was the total opposite, healthy and stable.
It's just cute and magical. I like the whole growing up together, marrying and having kids but with Jean and Scott all this it is enriched by mutant and superhero crazyness. you could say that about any other super hero ship of course but there is something that makes it special. there is something about it existing from the start and seeing it evolve and change (even for worse like in the last years) it makes the relationship feel like a real part of their lives and not just hooking up two characters.
I mean as far as i know morrison wanted to use Storm at first. We could have Scott/Storm instead of scott/emma as the greates romance of the 2000's or if Claremont didn't get angry for maddie, he could probably have never conceived Jean/Logan. I'm not trying to attack any of these ships they exist and are way healthier than jean/scott at the time
But Jean and Scott even in the current state were the relationship is a failure still are and will always be part of each other. It's in the DNA of their characters and i find it cute.
they can date other people, but they will never grow up with their other partners, they will never face/reject their possible future like jeen and tyke. They will never fail that hard with other people, and death and time travel aren't going to influence their relationship with other partners. I also doubt any of them will marry or have kids with other character.
