As the crew converses. The water is still.
Phaedra: So... children live here.
A purple ripple moves through the water, with a small "thoom" in the distance.
Phaedra: Or... LIVED here.
The ripples continue. Another louder "thoom" comes forth.
The crew is assembled at the edge of a dock, all facing away from the water's edge. 
Lani: But where ARE they? This place doesn't look abandoned.
Irving: They have red striped animal drawings on the walls. It REEKS of Bonefish here.
Pavel: If they can draw him, then they can see him! These kids are seabitten!
Phaedra: Or full Fata Morgana. But... Fata Morgana children have never been seen, at least not clearly. Still... they DO have to exist, right?
The snail on Cal's shoulder sits quietly, listening. Then, as the conversation continues, it begins moving down his shoulder, toward the ground. It is very, very slow.
Phaedra: Maybe, before they all get brainwashed... they get sent here. Who knows? it might be a slow process?
Cal intercepts the snail with his hand. He smiles.
Cal: Oh! On the move, snail friend?
A growing purple light appears behind him. He notices, and turns to look.
Cal: Hm?
