You know them?
Just hand the book over and nobody gets hurt.
I don't know how you do things in the ocean, but we don't negotiate with villains!
Siren Good. I wanted to do it the hard way.

Aquaman
[Siren and Mera confront him]
Stand down!
Siren Not very smart leaving your palace unguarded. But I never expected much from a boy king.
Aquaman
Atlantis is never unguarded. [summons sea creatures] Your trench creatures cannot win against the sea.
Siren Never underestimate a sea witch.
Siren [after Siren has assumed the throne]
My first decree is to have you thrown into the brig.
What?
Siren [Siren casts a spell that shackles Mera]
Now that my magic is stronger, I can have anything I want.
But, Siren...
Siren "But, Siren." You're always trying to stop me, but you can't stop me now. I'm more powerful than you and soon I will be the most powerful being on Earth!
There are superheroes at that high school more powerful than...
Siren Powerful enough to survive underwater? No. My predecessors to this trident never used its full power, but I will. I will start by sinking Metropolis. School's out for Super Hero High!
Siren [holding Wonder Woman and Mera at bay]
Who should I get rid of first? The little helpless surface dweller that I tried to eliminate years ago, or my own sister who insisted on saving her? Do you really think that you, with your weak walking legs, could've made it out of my ocean?
Siren [flashback sequence starts]
My own sister dragged you to the surface. She even dared touch her feet on the shore, waiting for your inferior human lungs to gasp the putrid surface air.
Siren [Young Wonder Woman coughs up water. Young Mera smiles at her, but when she sees Diana's mother coming, she dives back into the water. As Young Wonder Woman is carried away by her mother, Young Mera waves to her before sinking back beneath the waves. The flashback sequence ends]
So, first place on the annoying scale goes to my goody two-shoes sister Mera. Trident, destroy her!
Hawkgirl
Bad news. Metropolis is still sinking!
Siren Ha! Ignorant air breather! No one can stop what the trident has started!
Me? But what if I use it and go power crazy like Siren? Maybe you or Bumblebee...
[grabs her shoulder]
Mera, you love the sea and you have the heart of a hero. You can do it.
[Mera takes the trident and it starts to glow]
Sea, be calm!
[the trident's power calms the ocean and expels the water from Metropolis]
