And I forgot that I want them there all night. That I had carefully situated one scene for the morning twilight with the sky all stained with color but the sun not risen and the landscape all in shadows -- even with their leaving for another place before sunrise proper.
And that one scene is right after they leave the labyrinth. All right, there can be some to-do first, but they can give the highlights quickly, and then the adults' reaction is to stick these two, and another two pupils, in a safe, secure location. Which is where the next scene happens.
sigh Time to drag it out.
Good thing it's wandering in a labyrinth, 'cause it would be a lot harder in a lot of other activities.
