* Well, provided Diana remains immortal; I can't remember the last time Supes had to give up his heat vision in order to marry Lois or J'onn had to surrender his shapechanging as the price of living in the mortal world, but for some idiot reason Wondy writers just fucking love to rob Diana of her immortality. Fortunately it never sticks.
There's probably reams to be written just on this concept. I mean, it's so common, the whole "fairy girl gives up immortality/powers" to be with a man, while if the man has powers it's usually "fairy girl has to learn to be a good wife to man with powers." I think men have had a kink for centuries about the idea of making immortal women mortal through love.
