Theo skips sleep pretty often, so when he does actually sleep he tends to sleep for a while. Kaede will probably wake up before he does.
Except for the fact he would have had to backtrack a bunch through the cave. Because something would have bitten him or trapped him or somehow impeded his movement and he's able to fly quite quickly and much more peacefully over-and-around the stupid cave instead.
He wonders if it's man-made, an intentional trial. Maybe he was told sometime. He doesn't recall.
He does. It's very boring.
He might try making a miniature replica of his house, in detail, very slowly. Golly, doesn't that sound like fun.
He'll keep going, then, unless it starts to catch up.
In which case he will try raining small bits of alkali behind him, in low quantities so he doesn't destroy too much of the environment.
Theo does not immediately collapse when dizzied, manages to continue for a bit, and so long as it doesn't actively screw with his spatial memory he will rain alkali down on the thing.
He's so glad it obeys his indestructibility and the fact he likes his head.
He's less glad about the sonic boom.
He falls, briefly, then catches himself.
Another brief fall, another catch, and then some modification of his wings to make them a bit sturdier and he aims downwards to pick up speed.
Possibly risky but the only thing he really risks is smashing into the ground.
Sure, feel free to do that, but then Theo will shake himself out of it and he's moving quite quickly and then he pulls up and tries to get away.
Any convenient obstacles he can dodge around to get out the way?
Yes. Perhaps he should have. Maybe he will, once he gets away from the thing, and in the meantime, alkali. (Slowly.)
