Willem Dafoe: Vulko
Mera : [about Orm] Once he is named Ocean Master, he will be unstoppable.
Arthur Curry : I don't know these people. How can I make them accept me?
Nuidis Vulko : By winning the hears and minds of the people, by proving that you're worthy. And by retrieving this.
[takes out a map showing a trident]
Arthur Curry : I already got one of those.
Nuidis Vulko : Not like this one, you don't.
Nuidis Vulko : The ocean is not just our home, it is who we are.
Young Arthur (Nine Years Old) : You can talk underwater!... Wait, I can talk underwater too! This is awesome!
Nuidis Vulko : We can do so much more than talk. Being Atlantean is more than just being able to breathe under water, your body is equipped to survive in the extreme cold and pressure, and your eyes adjust to see in the darkness.
