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.
They do not sink that deep, he is indestructible and they can fuck off because he knows how to make acid and he has some convenient matter lodged in their stupid mouths.
He hopes it doesn't just totally fail to work.
He heals up and then flies upwards again, hoping the floaty thing is not fast enough and digging upwards because that should get him out.
Yes, well, if that thing doesn't work after like ten minutes of trying that is in fact what he'll do.
Acid! More acid, slowly if he has nothing to work on but – oh look they're in a cave he can make bits of the ceiling rain acid.
Yes, yes, he can totally do that and get acid all over himself, gosh, isn't this painful, but at least he's not immobile because he got his wing bitten.
Not yet, at least.
His wings can be rehealed quite quickly, actually. And he's not destroying it all, he's just… killing the fish. He's not melting all of the roof into acid.
… And then fly up through the hole in the ceiling? He's hoping the hole he made earlier is still visible but if not he'll just dig upwards somewhere.
Of course there is.
Well he'll just take that and go see the meteor dog. Which is hopefully still stuck in the ground and totally amenable to being killed by acid.
Gosh, perhaps it died from lack of moving room or something, how terrible.
He flies back out the cave. He's pretty sure it wasn't that hard a route to go back along.
