She is going to have to learn private thoughts.

"Avalor, where are you? It's suppertime," says a foster mom. "Darling have you seen Avalor -?"

"No, I thought she was in her room?"

"She's not in here unless she's hiding - Avalor don't hide -"

Elves assure her that they aren't offended that she doesn't understand how it's disgusting, children shouldn't know about such things at all. 

She is going to have to learn private thoughts if these Elves won't shut their faces about her great-uncles who loved each other and doted on her and one of them was beheaded.

Presumably there are reds who love and dote on each other? The existence of disgusting people who love each other doesn't prove anything and definitely doesn't make it okay. 

Maitimo tells them to maybe drop it please. 

The Elves are stupid. Maybe not Maitimo.

Public thoughts can be declaimed from the balcony of her room in the city house where she used to live, she used to be allowed to make announcements from there. Private thoughts are under her bed in the wintering house, where she had a pillow nest and it was dark. The Elves being stupid goes in the pillow nest.

If the Elves still hear it they do not comment on it. 

Fine.

A foster mom looks in the wardrobe and starts pushing clothes aside.

At the back of the wardrobe there is - no back of the wardrobe, just more clothes.

"...Darling come look at this."

Other foster mom comes and looks. "What in the world...?"

"Avalor?"

"Avalor are you all right?"

Elves look at each other and go back to singing the sad song.

A foster mom steps all the way through the wardrobe into Maitimo's room.

Maitimo is at his desk again. He turns and waves because he can be polite even if she is disgusting especially if he doesn't understand how.

"...um." She looks at his hair, but she also notices the ears and doesn't tense up quite as immediately. "Hello?"

"Hello. Only say a bit of Voan. - magic," he adds, pointing at the wardrobe. "King sent -" gesture at the Elves who are responsible for wardrobe. "I am Nelyafinwë Maitimo."

"...Darling there's a - an alien? Who - speaks bad Voan?" says Foster Mom #1 in Oakhar. "Your Voan's better -"

"An alien? Are you saying aliens abducted Avalor? If we tell the Emperor oh, yes, that Voan child we were looking after, abducted by aliens, we're never going to get a permission -" Out pops #2. "- wow."

"Hello." Points at wardrobe. "Magic. My father says Oakhar a bit - Father -"

His Oakhar is not quite as good as Avalor's yet. "Oh, hello. Welcome to Tirion. Your world sounds very interesting if completely appalling."

"That's not very diplomatic," he complains in Quenya.

Foster Moms blink at them.

"There are aliens in Avalor's wardrobe?" says #2.

"Avalor made first contact with aliens?" surmises #1.

"It looks more like the wardrobe permits transit between worlds than that either world is properly conceived of as inside the wardrobe," he says.

Say 'Avalor had only complimentary things to say about the Oakh Empire and the generosity of her foster parents.'

But she was thinking about how much she hated them! "Avalor had only complimentary things to say about the Oakh Empire and the generosity of her foster parents."

"This is - bizarre. Very bizarre. We need to tell the Emperor."

"Tell him that there are aliens in our Voan fosterling's wardrobe."

"He can come see! Or send someone! It's not like we'd be making it up!"

"We could send a diplomatic envoy but require a day to assemble one."

"That - sounds like a good idea - where is Avalor, is she all right?"
