Simone's Atom did by far the most to actually make her a sensical character (not that that in and of itself i saying a whole lot), so hopefully that continues here.
Though when Wondy herself appeared there was this attempt to make Giganta some huge epic rival whose presence can cause Diana to totally go berserk, something not remotely justified by their history; if I had to name one real problem I had with Simone's run it's how she frequently attempts to retroactively impose character history (Etta being her closest friend, for example). Diana and Giganta have met like three times, and she's never been much more than a joke.
