He checks himself in the mirror. "Yes...that's exactly what that is."

"Why did your face turn a strange color?" she asks, mouth full of water and toothpaste and toothbrush.

"Umm, no reason."

She finishes.

"Okay. Let's go?"

"Let's go!" 

She follows him wherever.

They exit the mountain fortress and make their way to the beach. 

"You know, most of my tribe doesn't speak English, can you make a thingy so you'll understand them?"

"Hmmm, maybe? I can try. What do they speak?"

He proceeds to utter a series of clicks and whistles.

"...wow okay. Ummm. I dunno if I can make a thing to translate that."

"It's okay if you can't, I'll try my best to translate." He takes her hand. "Now make it so you won't drown and let's go!"

Forcefield and mask are a go.

Much splashing as they make their way into the water.

Splash splash!

"I thought you couldn't swim a couple days ago?"

"I don't need to swim if I can breathe underwater and use flippers."

"Poor Sadde, sayer of wrong things."

"I'm not, I'm always right!"

Eventually, they enter what seems to be Michael's home. Dozens of mer flock around, tending to the day's tasks or just milling about.

Oooh. What are they day's tasks?

Mainly making sure there's enough food for everyone, caring for and teaching the children, and maintaining their dwellings, which appear to mostly consist of caves or woven seaweed. Also, the creation of tools. 

A few mer-children about their age swim up to the two, and start chattering. Nemo is among them.

She does not speak that language!

"Um, they are wondering if you are one of the goddess's babies. I told them no. Is that okay?"

"Sure? I'm not one of the goddess's babies."

"Oh, you're a girl today."
