I know I'll get heat for saying this (because I have before), but if /when Scott and Jean get back together I hope they don't go overboard on the sappy "romantic" dialogue. The preview of the last Mr. and Mrs. X made me cringe when Rogue referred to Gambit as "dear". I think too many times writers use stereotypes, tropes, and generalizations when writing characters that are "in love". I think some have watched too many Hallmark movies or Disney movies. I want to see (and maybe there are good examples of it and I have just yet to witness it) couples in fiction being written as smart, sexy, and independent of each other while still being in love. Being in love with someone, to me means commitment more than using sappy language or pet names or referring to your significant others as "dear" or "babe" or any of that stuff.
I would love to see another Adventures of Cyclops and Phoenix miniseries where Scott and Jean are fighting together, supporting one another, and redeveloping their friendship before they become lovers again (I really do think they will end up together eventually). I want to see them both be vulnerable but neither of them need to come across as needy or emotionally abused by their complicated relationship history. It will have to come across as organic. There is a lot to explore with them and they can't just ignore Emma Frost and I would hope they woulnd't ignore HCT (but who knows they may overlook all that and just rebuild them slowly starting with HOX and onward).
