It was Matrix the whole time!
Yeah, that ruins Matrix, but at least you fix Diana.
There's no fixing this without demanding a pound of flesh elsewhere. Too much has been done.
See, I thought his signature move was moving heaven and Earth to retool all projects into featuring Diana, Kate or Rene Montoya even if it meant sidelining the protagonist.
Furthermore, you're implying she dies in the blast, but we've seen Superman survive a nuclear blast ergo this is another example of how DC doesn't respect Diana and that she is, in fact, a weak character who deserves to lose her book to a man to end the rampant sexism plaguing the character.
Back in my day we just went into the restroom and said something three times if we wanted to summon a bad time.
