Storm and Forge were a bit of a strange couple because nobody outside of Claremont was ever interested in them. And even Claremont never really did much with them after Fall of the Mutants. When Forge learned Storm was alive again there was no epic reunion or anything like that and instead Forge was flirting with Jean and Destiny was making prophecies that Mystique and Forge would end up together.

I'm surprised Alex and Lorna haven't had a single kid in any AU.

Betsy was never a damsel thankfully. I remember right before The Twelve storyline when Wolverine is exposed as a Skrull, Warren goes off to warn Betsy as he fears she'll be slim pickings without her powers (due to Psi-War) but she ends up saving him.

Your comment makes sense about why the non-superpowered characters tend to get written off. Or even killed off like Candy or Sara Grey.
