Lena Hellegren: You look troubled, Father.
Dr. Hellegren: Disloyalty is always troubling. But it is not your problem. A rotten apple.
Lena Hellegren: Rotten apple?
Dr. Hellegren: UBRI has a spy, it seems. Delivering our secrets to the enemy.
Lena Hellegren: I didn't realize you had any enemies, Father.
Dr. Hellegren: You are very naive, my dear.

Mera: You have no time. The ocean's are in danger.

Lena Hellegren: An extraterrestrial mermaid?
Jason Bates: You can't put labels on Neri. She's like... a guardian. Her people know how important the oceans are to the balance of this world. Even if we don't.
Lena Hellegren: And where does this Synchronium come in?
Jason Bates: Well, there are nine pieces that make it up. Each bit was sent here separately. Neri's father was one of the few to be trusted with the secret. The Synchronium's supposed to fix what's going wrong with the oceans.
Lena Hellegren: But how does it work?
Jason Bates: Well, we don't know. Neither does Neri yet. But it's incredibly powerful and we know what happens when something like that gets into the wrong hands.
Lena Hellegren: Like my father's.
