Arthur Curry: My parents were of two different worlds, and I was a product of the love that they shared. A son of land, and a son of the seas.
Orm: You were the reason our mother was executed. And I've hated you for it ever since. But I do not want to kill you, Arthur. I am going to give you one chance. Go home. Do not ever come back to Atlantis. You are not going to win this. A war is coming to the surface whether you like or not. And I am bringing the wrath of the Seven Seas with me.
Arthur Curry: You know I can't let that happen.
Orm: I know.
Jarhead: You the Fish Boy from the TV?
Arthur Curry: It's Fish Man.
Queen Atlanna: I am Atlanna, Queen of Atlantis.
Thomas Curry: I am Thomas, Keeper of Lighthouse.
Queen Atlanna: A king fights only for his own nation. A hero fights for everyone. You fight for everyone.
Mera: You think you're unworthy to lead because you're of two different worlds? But that is exactly why you ARE worthy!
Orm: My brother has come from the surface... to challenge me for the throne!
Arthur Curry: I call it an ass-whooping.
Arthur Curry: My father was a lighthouse keeper. My mother was a queen. But life has a way of bringing people together. They made me what I am.
Arthur Curry: I'm no leader. I came because I have no choice. I came to save my home, and the people that I love.
Mera: Your half-brother, King Orm, is about to declare war upon the surface world. The only way to stop his war is for you to take your rightful place as King.
Arthur Curry: Trust me, I am no king.
Arthur Curry: I'm no leader. I'm not a king.
Mera: Atlantis has always had a king. Now it needs something more.
Arthur Curry: Well, what could be greater than a king?
Mera: A hero.
Answer: Just because he's the bad guy doesn't mean he didn't go to college. He could be a genius and gotten a brief working knowledge from the Atlantis soldiers.
