Evening. The channel wand is a dark exclamation that finally means what it meant.

A seal—just a seal, which is not a small thing—slides past the inner edge as if it had been practicing all its life, which it has. It does not fear you. It does not snag the century of boats you just untangled with a stick.

In the morning there is fish-sign in the mix, fry stitching, the estuary going about its unblank work.

Brine thinks that is funny, in the selkie way: a breath out, eyes kind. “Markers,” Brine says. “People feed the channel that feeds the boats that can then afford to leave us our rock. A circle even a ledger can like. Do not make a relic of the wand. Make a habit.”

You laugh, because you are tired and because the joke is science wearing wet boots.

Pip fetches Pell a report. Kade, seeing you both filthy and unpaid in silver, still brings bread, which is a vote.

Mutualism starts tiny. The coat may still need a council. Or it may already be on the Stack because someone listened while you were lifting stone. You put your palm on the wet perch and imagine the mouth learning a new verse that includes a harbor kid.

THE END

What you learned: estuaries mix fresh and salt into a nursery; channel marks are tiny maps that keep boats from guessing. Restoration can be a wand set true, not a speech. When a wild seal does not fear you, you have finally behaved like part of the picture.
