So Nika waits by where she expects grownups to come in, and she reads about magic on her pen.
"Ivan found it! And he got me, and I got Miles, and there were our grownups in it, and they gave us stuff and we came home from it. Look at this!" She puts her pen in drawing mode - this takes her a couple tries; it's not that accustomed to her gestures yet - and draws a squiggle through the air. "One of my grownups invented these!"
"They didn't look like me the way Miles's grownup looked like Miles and Ivan's grownup looked like him - Gregor, Ivan's grownup was so boring, it's sad - but the bar said they were my grownups, I'm going to be like them when I grow up except different looking. And a dragon. And adopted, they weren't adopted."
This calls up a tutorial! The tutorial explains that a pen is very like a comconsole. It tells him that he can change its default gestures if he wants, and explains the default gestures to a) make the pen work almost exactly like a comconsole, b) draw, c) write with gestures in Cyrillic, d) do specialized pen-things that comconsoles cannot do. He is supposed to imitate these gestures as they are introduced so the pen can learn how he holds it and moves it. It is a very good tutorial. Linyabel hires excellent help.
