James Robinson gives us some details on Earth 2.
Sounds interesting actually. Might pick up issue #1 to check it out.
We actually love how he describes Diana.
"More importantly, she’s the last Amazon, so she has her heritage that she carries with her. It isn’t just that she’s lost her sisters and that whole world, but also that she has this sense that she has to carry on for all of them, and be even stronger and even better for all of them."
Of Superman, it does not sound as if he will lose his moral compass (as he should not…he did not chose or become Superman because of Lois) and it might be the circumstances are simply very challenging and not black and white.
"the events of her tragic death are not something that we actually will be showing, but they are something that drives Superman on in his actions in the comic book."
So let’s hope we see Clark and Diana and Batman act as heroes and display one of the most admirable attributes that gives us our humanity: to weather and overcome even in the most trying of circumstances.
