They can tell the red that they should stay for a few minutes but for all they know the red has things to do and will be in a hurry okay?

Yeah of course.

They tell the red that. The red looks nervous and confused. "- okay -"

He presses his nose to the glass. "Hi! Did you hear about there being aliens -"

Headshake.

"Oh, okay. So, a little while ago aliens made contact with the empire. We have lots of magic. On our world we use magic to do the red jobs. We could do that here but everyone keeps making it impossible for us to talk to the reds so we can't sit down with you and figure out what you need to be safe and what you want to be happy. And the King can insist - since they really want the magic to colonize new planets with - but he doesn't know what to insist on because that depends on what the reds need and want."

Now the red looks anxious.

"If I had a safe way to talk to you without them overhearing, would that be okay with you?"

"I don't - understand why - how old are you -? Sir."

"Forty. We age differently. My name is Maitimo you don't have to call me sir I'm not your prince."

Him being a prince is not helping!!!!!!! "- ah -"

"Would you like it if I just sang a song from Valinor instead."

"...I'm. Sure the songs are. Lovely."

He starts singing. 

He gives the poor terrified red a couple minutes to calm down, then says I can communicate like this. No one can hear that we're talking.

The red jumps.

I'm sorry I'm scaring you I won't let anyone hurt you.

Aaaaaaaaa magic alien.

It is possible that Avalor is right and reds are just not that smart and he will have to apologize for doubting her. 

He gives him a while more. Please don't be scared we have lots of magic I can keep you safe.

How are you going to do that?!

I can tell them that I really liked talking to you and want to come sing to you again next week. If you don't think that'll work I can come up with some reason to insist a Vala come here and then they can protect you.

A what??

More powerful aliens than me. The ones who are terraforming planets for the empire.

It is really much safer if everybody forgets about us.

Why?

Because then they leave us alone.
