Cam is dipping a grilled cheese sandwich into a bowl of tomato soup when he feels the summons. He goes ahead and grabs it. Doesn't even drop the sandwich.
"But stuff I make still seems to work on the physics I'm used to. When I have room to make it, which may not be the case with anything as big as a planet or a sun."
"Quite. Also even if space works like I'm used to it will take weeks for me to map the system and figure out where I could safely put something and then put it there. Probably not a priority."
"I want to generally get a feel for the unphysics. I don't want to assume it's like video games and get tripped up when it fails to be like video games in some way, or winds up being like different video games from those with which I am familiar."
He flies to the island with the glass-blocked treehouse.
He goes home. He makes dinner for himself and Sable. Over lamb and cauliflower and clam chowder: "Do you want to try some futuristic painkillers for your groundsense thing?"
"I don't know, that's why I said 'try'. I am a well-qualified medical demon but I have no idea whether your thing will interact with painkillers at all."
He ices them all, grumbling, and stays up the rest of the night with a book, floating in a pool chair on the assumption that they probably don't swim.
It's a pretty deep pool. He ices them whenever he hears splashing. If he has to empty and refill his pool because of this that will be annoying but so far gore disappears.
