"Is that why you're all gray?" asks Charles.

"Who cares, a mermaid?" enthuses Lilly.

"Yup!"

"Show me!"

"You mind going for a swim?"

"...I can't breathe underwater."

Martin zips off for a second. "Here," he says, handing her a breathing mask. 

She eyes it mistrustfully. "What's that?"

"Breathing mask, let you stay underwater for a long time."

"How do you use it?"

"You strap it over your mouth and breathe, silly."

"Okay!" She puts it on.

Michael takes her by the hand and leads her into the water. 

She follows willingly!

Stan decides to go find Jacob and Sadde. "Michael's taking Lilly to meet his tribe if you wanna come back."

"—yeah, okay."

Back to the south beach! "So, how's not being grown up super-murderers treating you guys?" He looks at Nat. "And what's with the armour?"

"I like it," she says defensively.

"Stan, you shouldn't criticise other people's fashion choices."

Jacob giggles.

"I didn't say it was bad. Though the sun does feel nice."

"I think we're ignoring the big issue here. Namely, that Carol has paint powers."

"Yep!" she says, grinning.

Charles rolls his eyes. "Laaaaaaame."

And now Charles is trapped in a rainbow bubble. "Could you show us?"

So she makes a patch of sand turn red...

...and then it gradually starts being consumed and turned into nothing.

"Can you do other colours?"

"Yeah but I don't know what they do."
