Enchantress seduces Wonder Man and gets him to fight some Avengers and feature her as a costar in one of his movies.
Seriously. She can make any man do what she wants, but instead of seducing Steven Spielberg or Hal Hartley (maybe she likes the indie flicks), she goes after a dude who only seems to make bad films.
That’s about it. Except for the big revelation from Ronnie Reagan, above.
