That was "Batman: Under the Red Hood" only. Back in "A Death in the Family", Ra's had no part in the Joker's operation. And Talia's actions in "Under the Hood" were done independently of her father.

But yeah, my guess is Orm's disgrace involves Aquababy. But I think Arthur Jr's still alive, and the disgrace is mostly due to his unmasking (and subsequent loss of his orgnaizations and thus use to the Light).
