"Thanks!"

"You're welcome!"

And then they can go find the park where Odette is hanging out in a tree. Fortunately it is within walking distance. Illia has taken a train and it is not an experience she is eager to repeat.

She gets double-takes but no one else identifies her as the green local instance of her face.

Reasonable.

They reach the tree. "Guess what I found!" Illia calls up.

"Hm?" Odette says. She looks down.

"...Uh."

"Hi!"

"Hi, uh, any idea why you look like me?"

"As far as we can tell I am you--my name's Ada and I have a twin sister named Amila who looks exactly like Illia and a geneticist parent and a general sense of social malcontent. Which is, alas, harder to leverage than it need be because everyone expects frivolous social malcontentment from silly green university students and correspondingly takes it less seriously."

"...This is incredibly bizarre."

"Mhm."

"I mean leaving aside the fact that I apparently have an alien duplicate I kind of would have expected your hair to be a darker shade."

She bursts out giggling. "It naturally comes in darker! But it's not green, so I bleach and dye it."

"Her father--who, uh, appears to be our mom and vice-versa--is grey."

"...That's weird."

"I know!"

"What about this isn't weird?"

"Fair point."

Illia decides to email Peka.

You'll never guess what just happened!

Oooh, a guessing game. More aliens? You got home? The polar reds are opening a jewelry shop with outgoing shipments sent through decontam?

None of the above. I went to interview a random Voan green about learning magic and she appears to be--Otet, only Amentan and Voan and green.

What does it mean to be Otet except Amentan and Voan and green?

It means she looks like--

"Is it okay if I take your picture to send to my red cultural consultant?"

"...Uh, why are you talking to your red cultural consultant about me?"

"Because she's my friend."

"Alright then."
