Yost joins the vast ranks of writers who like to throw Birds around without ever having read a single issue of Birds. His Helena not only wears the Jim Lee Hush outfit, she behaves like the Hush-era Huntress. Kill-crazy, obsessed with how much Batman and Oracle don't like her, not trusted by Babs herself.
Oh and she regrets her pledge to clean up Gotham's mob, because she hates Gotham now, it's gotten too hard and eaten her soul or whatever. That's not a Huntress-specific problem, all the Bats get it from time to time, but it's still noxious bullshit from any of them.
