Do you really think you can defeat your brother, after all he is the one who banished you to the Underworld in the first place
I don’t need reminding that Zeus is the source of my misfortunes. But yes. With Zelena at my side and the Dark One’s dagger and the Olympian Crystal in my hands, I can and will destroy my brother.
And when I do, I will be king of Olympus instead of a decaying Underworld, and Zelena will rule at my side as the goddess she was always meant to be.
