"Oh, and Afen wrote back, said he'd love to learn more of your languages."

Felix gives a tired laugh. "Sure. I am pressed for time. But I wouldn't mind scheduling something." head tilt. "I am hardly going to be pressed for money, but what would be..." he waves vaguely, "the relevant laws if I wanted to sell Earth media?"

"- we'll figure out how to make that work. Translation might be a problem."

Nod. Thinking. He looks around for a nearby pen and paper and asks for some if none is visible.

He can be provided with both!

He writes "can you understand this?" and shows it to her.

She in fact can understand it just fine.

" - yes."

"Huh, I wonder if it extends to the things I create. I could then hire someone to type it all out for mass production."

"You could! I expect it'd be very popular."

Nod. "Do you have anything else to discuss?"

"I don't think so. Thank you."

Nod. "Tell Afen that I'll contact him once I have more time."

He leaves.

The police go into the red neighborhood in hazmat gear and drag everyone out for questioning.

And guess who shows up to check on things.

"What is going on here?" He asks no one in particular.

"Red with dangerous magic, need to figure out who it is. Do you know?"

"That was not the agreement I had with your government."

Felix searches for the family, not giving away when if he spots them. How are they treating the crowd?

"Then take it up with them."

The reds are perfectly still and terrified. The guards have sticks but aren't currently beating people. The three of them are in the crowd.

Are there signs that they beat some people before Felix arrived?

"No. You call them right now and tell that I said to call this off."

The police ignore him entirely and hand the next few off for questioning.

Yeah some of the reds probably got thwacked. 

How about if Felix stands in the way. He starts calling the weather. The winds pick it up and the air gets even chiller around the guards. "Don't ignore me! Call this off now! Or I won't make them their precious cities!"

"We don't take orders from you," a grey-haired woman says, "and we sure as hell don't take them from the weather. You're threatening the wrong people. Get out of the way."

"I AM NOT THE ONES WHO IS BEATING INNOCENT PEOPLE!"

"We're not even beating the garbage." She attempts to bodily move him out of the way. 

"DON'T CALL THEM GARBAGE!"

And Felix switches the air from cold to hot, making the impact much harder. It isn't fire, but it is temperature high enough to cause a heat stroke.

Someone draws a gun on him. "Stop it."
