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.
He thinks there are some more corrosive alkalis, he'll go through a few alkalis he knows and hope that they do more damage after the acid is neutralized.
(Augh.)
How about the teeth go dissolve too. He thinks that's doable. And the rest of the mouth. And the face, and the whole head.
Stupid dog.
How nice.
He heals up and then recreates his clothing and goes to fly out of the cave.
It might have photoreceptive skin or it might just be plain magic, he doesn't care because he is trying to stay out of the way and can alkali it.
He is staying away from the cloud of pollen. He's backing away and holding his breath and covering his nose and oh how convenient he doesn't even really have to breathe, how about he make it not able to get inside his body and not let it touch him too.
Still alkali.
He can heal himself up and then he can put some metal around him and you know what he thinks clothing that covers him properly would be nice so he'll just get some thicker clothing like – how about a hazmat suit, he doesn't know precisely how they work but he knows the material and can get most of it.
The pollen can be carefully removed. He can seal off parts of the suit and expel it and recreate it.
Stupid plant thing.
He rearranges the hazmat suit to attach to his skin around where his wings do and then uncovers them so he can actually fly and continues on his way.
Then he'll be out and decide to fly over the cave, thank you very much, and remove the hazmat suit unless the fog looks likely to be weirdly acidic.
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.
