"I'm not even sure if normal visible wings would be compatible with the stuff I'm made of." 

"No? You eat normal stuff."

"Yeah, but I don't, like, have normal blood. Wings whose cells expected to be fueled by normal blood might find themselves disappointed." 

"Oh. What do you have instead?"

"I don't know what to call it but it's yellow-green and more viscous than normal blood. And has a stronger smell." 

"Huh. Well, blood does come in different colors, horseshoe crabs have it blue, but maybe it's technically peculiar lymph or something, couldn't tell you."

"I have no idea but I'm pretty sure it's a Yog-Sothoth thing and I expect Yog-Sothoth things to be weirder than crab things." 

"Seems likely."

"Wilbur's way more human-shaped than me and he has the weird blood too." 

"Honestly it's bizarre that crossbreeds work at all."

"I think the answer to that one is probably magic." 

"Yeah, probably. Not a very explanatory answer."

"Well. No. But science has to start somewhere." 

"This is true. Do you have some science you want to do?"

"I think I want to learn more non-occult chemistry before I try doing chemistry to any of my own tissues but that's the first place I'd start." 

"Well, let me know if you run into a dead end on your computer."

"I will. I'm glad I don't need to sleep much, putting this down to go to bed would be unbearable." 

"Sleep is a frustrating need to have! How much do you need?"

"A few hours a month." 

"That's about as often as I sleep under normal circumstances."

"Why d'you sleep?" 

"Sometimes I'm reading a great book, forget to drink coffee during, and notice I'm tired and comfy and set up for a good shot at good dreams. That sort of thing."

"Oh. Yeah, that sounds nice." 

"I don't expect that to happen for at least a year though."

"There's so much stuff to do right now!"
