Title: 流星 - Shooting star
Brief summary: The merrows are guiding the ship to Skellig. The boy disappears. Schierke thinks the boy might be from Elfhelm, or that he might even be the King of the Flower Storm himself. There's also mention of a branch relating to the moon, which clearly refers to the 5th and 8th pictures of the preview. Branches, sure, but of what tree? Ganishka's? The Elf King's, if he's associated to a plant like Chich? Extremely interesting.
That at least can explain how the boy can travel seemingly anywhere he wants: the tree (whichever it is) is astral in nature and big enough that it goes through the full moon, like through a portal. And what about Schierke's guess? It makes sense from her point of view, but given what we know and the hints we've had, it seems wrong somehow. Unless the boy is a projection from the king himself and is meant to look like Guts & Casca's son would have on purpose, as a way to mend what has to be. Crazy theories.
In other news, Miura wants to move to a new place.
