He has not found a way to break her family's spell, by the time he comes up with a way to turn her entire body entirely human.

"Eeeeeeeee!!  Thank you, Uncle - I'll miss you!"  She doesn't hug him because she doesn't hug people.  (But maybe she WILL when her skin is SMOOTH.)

"...Llene, can you wait; I - I can probably find a way to crack it -"  He would say that there's more work to be done on the transformation, before it's ready.  If she were one of the people he lies to.

"...No.  I have to leave.  I can leave -"

"...Yeah, fine.  Okay.  I know you're dying here, or whatever.  - But I do think it'll be a lot worse on land; you'll be far away all the time -"

"I'll live."

"Very funny.  I suppose... shall we go, then?"

"Yes."

She drinks a potion and sings until she has two favorite uncles, and one of them hides in the back of the cave and the other squishes a pod until it bursts and envelops them both in a cloud of ink.

"Can you see us?" asks the pod-bursting one, after the ink dissipates.  The other doesn't respond.  The first swims over and claps in front of the second's face, with no flinch in response, and fixes his hair, still to no reaction, and then retreats and pelts a shell from the floor at him.

"Ow - no, I can't see you," the second whines.  So the first wraps a tentacle around Cyllene's arm and starts dragging her toward land.

He's quiet, as they pass through the merfolk settlement, but once they're clear of it he doesn't really shut up.  It turns out that he knows lots of things about humans, much more than he ever told her before.  He describes writing, how humans talk with ink and not-seaweed and make something that lasts, instead of something that's only as good as memory.  He tells her what he knows of their magic, which as far as he knows there's only one kind of.  And - he hesitates, here, but he does say that he's heard strange music, with no voice, coming from human objects.  He doesn't have a clue whether they might work for magic, that's really not his purview - there's still time, she knows, right?  If she wants to skip that one.

She just laughs.

Fine.  That's about what he expected.

It takes a long time, but not, actually, forever, for them to arrive at the shallows Cyllene's new necklace has been pointing them at.  Jupiter hits the point where he has to squish down to stay completely underwater and sets her on the sand.  She accepts the trinket.  He - incants.

She accompanies.

And she becomes - human.  Her fingers lose their webbing; her skin turns from gray to orange and rough to smooth; her lower half splits - she becomes much smaller, and her chest gets some fat on it, and her teeth get rounder, and she's HUMAN!

...And she needs to breathe.  Can she stand up on her own, yes kind of, although it helps to use her uncle like a rock to push off of.  And then she hugs him, finally.

"Aw, kid."  Hug, hug.  "You still wanna give up your voice?"

"Yes.  I'll figure out how to get it back, or if you do you can signal me."

"Yeah.  Yeah...  Let's get to it, then."

She sings until she doesn't, and she tolerates her uncle's drawn-out goodbye until she sits down underwater again, and then he pulls her closer to the shore until he can't really, anymore.

And then she crawls.

It hurts, a lot, more than getting hit by the ship debris did, but it's not damage; she knows to expect it and she can clench her (flat) teeth and - just - keep - going -

Though once she's properly out of the water she wants a break.  Flop.  One final wave in the direction of where her uncle might be.  Re-flop.

They did not choose a particularly busy beach. She might have a wait.

The good news about this curse is that it's meant to motivate her, so the pain stops pretty quickly once she quits trying to move.

So after a song-length she continues.

"Who are you?" calls a voice.

- Cyllene can understand her!!  (Ow.  Ow.)  Wave wave wave wave wave??
