Really? I haven't noticed any changes in Emma?... Also yeah they do despise each other don't they? lol... "If Scott were still around and he'd pissed them both off simultaneously, they would join forces against him, have cocktails later and then a hotel room." - I wanna see this sooo badly... I guess it kinda is the ultimate fanboy fantasy, but I mean if current Emma and Young Jean can be friends then that at least gives me a little hope lol... they really need to just sit down and have a heart to heart without Emma being mean and with Jean being calm lol. Yeah there's already plenty of Jean x Emma fan art/ fanfiction ( I think there's more of that then Jott or Scemma) but if they can make it canon i'd be sooo happy lol. I agree it'd take an incredible writer but I think they could make it work...
Teen Jean and Emma used to be friends/allies/master apprentice but that's over now.
If you want to see interactions between Adult Jean and Emma. may I suggest the current Jean Grey solo series. Ghost Adult Jean is hanging out with Teen Jean and in like issue 7 or 8 they make contact with Emma. I think you would want to see that exchange.
I believe they could make it work between the two just as I believe a good writer can bring Jott back and reinvigorate the long standing and widely renown coupling.
Its not so much a concept that is the problem but the execution is what matters most.
