Prediction 3.
In next episode they'll focus on relations between people on new fleet (the one going on squid hunt). After 15 minutes of slice of life, Ledo in his robot, accompanied by Kamina-clone in his Yunboro will start submerging, finally arriving at some great treasure (which will be some space technology familiar to Ledo). And then suddenly, lots of squids will appear on screen, and then... BAAAAM. Episode ends.
