Agreed. I do think there's WAYS to make it work, how characters like DJ and Pixie treated death in Way of X, for example (even without Onslaught's interference taken into account). Like someone like DJ who died at age fifteen/sixteen might very plausibly see a forced or artificial facade of cavalier-ness about death as a kind of defiance, a way of spitting in the eye of whatever fears and emotions he's still sorting through because of his death. But of course, we never saw anything like that actually play out on the page, so what we got was just 'oh death is so lol, we don't care about that.'
Nah, I think you can still have the exact same attitudes play out SUPERFICIALLY.....as a cover to mask the fact that these kids are very much Not Okay, as would be expected of kids who had to grapple with the reality of their mortality from a very early age....AFTER coming back from the dead. But like. Can we please see THAT part too???
