Rocma looks at the sea. Seems to be watching for something.
Idate is plotting something…
As we see, after talking with Shirogane and Yukisada, Rocma went to the top of Iceberg Island. She seems angrier now, but I think there's another reason for this besides Shiro. Something or someone seems to have appeared on the sea horizon. This is what obviously disturbed the previously unflappable polar bear. I think the reason lies with Orca. She was previously worried about Shirogane's intentions to go boat ride with his friend precisely because of the danger that meeting him would entail. Now, however, their danger has passed: we see that the troublemaker (Shiro) has retreated, and now only Yukisada and the snowman remain on the shore, clearly not eager to go boat ride. But now another problem has arisen. Perhaps this supposed "something/someone" is heading towards Iceberg Isle (or is the isle itself approaching this "something/someone"?), and now there is a possibility of encountering an unknown threat, or others may suffer the fate of meeting Orca, unknowingly swimming closer and closer to an unknown danger…
