Astri's group was all ready after two more days. Deanora will miss Astri very dearly since they have become very good friends. Astri said she would get in touch as much as she could.
The trip back was almost all peaceful. They were attacked a few times by Monsters, but whenever the Monsters felt Biggie arriving they would "swim" for their lives.
First, they go to the South Mermen Tribe, both to visit Koa and also to spend some days on land.
"Welcome. I'm happy to see you again." Koa says, but everyone can sense he is directing his words more to Astri.
Koa is happy to know Astri kept her promise and came back. And he's impressed when he discovers Astri and Beau are now spouses too, and that Beau had quit his position as Captain of Aquaterra to be with her, and that was his decision, not hers.
At night, Astri is walking on the beach with Beau, Kai and Elias. Beau and Astri are holding hands, and Astri hugging his arm to keep herself warm.
