the original trilogy actually didnt hint at any past love interest of ANY character lol
So thats why the writers and creative team have that freedom regarding the prequels and future movies of this franchise.
I agree with that.When Magneto said that "she was so beautiful" line, I took it as perhaps a mixture of his attraction to her, but more so, how Magneto views the mutant race as superior and beautiful.
.Opening night of X2 during the scene where Mystique invades Stryker's base and
Wolverine: "She's good."
Magneto: "You have no idea."
That got one of the biggest groans/laughs from the audience.
"The old guy and the hot blue chick got 'together,'".

I think Bryan Singer clealry wanted you to think they were together with that
scene![]()

Well that could have happened in 10 year gap.Also explans what happened to Azarel.Magneto killed him for sleeping with mystique.maybe she dumped kurt to prove her lyalty after her infidelity with azarel
