Zoyah holds up her hands in a nonthreatening gesture and moves to button the skirt for the strange green person.
After the buttons are done, Zoyah says, "Okay, so, um, do you want to come to the castle with me? Kerem speaks like fifteen languages, I bet he knows one you know." She accompanies this acknowledged likely-pointless speech with a gesture and a few steps along the beach.
She studies the steps eagerly, then tries to get to her feet and follow. Her legs tangle up in the skirt and she falls on her face, then spends a short while cursing viciously in absolute silence.
Zoyah offers her a hand to help her up. "You must've got, like, really thorough sea legs if you can't even walk anymore. Or maybe you're dehydrated? I hope you didn't drink the seawater."
The stranger takes Zoyah's hand and, with its help, manages to get up on both feet. She wobbles. She takes a step. She takes another step.
"Mother! Father! Cymebliiiine!" calls Zoyah. "I found a lady with gills and cosmetic transfers and she doesn't know Loegrian or Aquitiniais or Latinitas and I dunno what to do with her!"
Cymbeline is the first person to respond to this call. He comes out the side door and looks quizzically at his sister and the green lady.
"Okay, well..." He points at himself. "Cymbeline." He points at Zoyah. "Zoyah." He points at the green person.
"Okay, well... do you want to come inside?" he says with a corresponding inviting gesture. "We can show you to Kerem, he's better at some fiddly stuff than I am..."
She falls over. (It's been happening a lot.)
"That's an accomplishment." He helps the green person up and puts his arm (quite chastely) around her.
"Coming!" Kerem calls back, and presently he appears within view. "Goodness gracious."
"We've tried all our languages," Cymbeline says, nodding in Zoyah's direction, "but you've got a few more?"
"Yes, of course," says Kerem, and he tries a few more languages.
The green woman just blinks at him. And leans on Cymbeline. In a way that might be described as 'overly familiar'.
"...Okay... Now I'm wondering if she's deaf. Zo', go behind her, shout suddenly?" suggests Cymbeline.
