Tommy also said that this underwater village did experiments on Prospect #1 and brought him back to life. As far as I can tell, Prospect #1 was floating in the ocean after "Swim to the Moon" when he either fell into the water, or this Queen Sea entity captured him. Siren like, they tell him that everything will be fine and they won't hurt him. They do some kind of tests on him, he must have died, and they brought him back to life and returned him to his boat, where he drifted until he crashed on the island from "Specular Reflection."

"Queen Sea will give back life" (Prospect #1 died, and they brought him back to life) "We used you" (They did tests on him) "Your purpose is clear" (He has a destiny to fufill) "We never knew" (They didn't know who he was when they captured him)

"Floating back to the surface" (They return him to the boat)

"(Tentacle hearse transportation... Actual happenings or the distant mind?) " (The method of his return to the surface, and his vauge awareness of all this happening)
