Sue reports this situation to the link.

"No, no, it's not all right, we're sorry, we're sorry," he says desperately, like he expects the words to be a charm against some evil that just - isn't - working. "Sorry sorry sorry -"

Sherlock pushes her love for Shell Bell to Sue, trusting that he will know what to do with it.

He bounces Sherlock's message to the intended recipient.

So what the fuck do we do? says Kas, heading back the way he came.

Tell Shell Bell to bail out, tell her to teleport to Amariah's house, or the dock, anywhere that's not here, we can start over from scratch if we have to. Scream it at her, get her attention.

Leave the harpy, says Sherlock, through Sue. Teleport away. Teleport to me. I love you. I need you. Come here.

Try wishing her out directly?

"You shouldn't," whispers the smew.

"I should. I do. I will continue," she says.

"What is the harpy doing to Shell Bell?" Cam demands of the alethiometer.

Sherlock cuddles the smew, but doesn't hold him prisoner.

The alethiometer says to Cam, "The harpy is causing suffering in her."

"How?" Cam snaps.

"Shouldn't - shouldn't," the smew is murmuring under his breath, and eventually he manages to flop out of Sherlock's hold and fall gracelessly to the dock, where he huddles and whines to himself.

Ghosty is spread out a little too thin to get clear details, but there is a harpy by Shell Bell, and it is shrieking. She forwards this information to the link.

"It is in their nature," says the alethiometer.

The smew is not doing too well without Sherlock's comfort to mitigate whatever the harpy's doing, and he's wailing his lungs out where he's flopped on the dock but refuses to make a move towards his person's girlfriend. Occasionally he looks at her, but then clumsily hides his face under his wing.

Kas, can you get any better answers out of your alethiometer than I can out of this one about what's going on with Shell Bell?
