(A panel showing Dee and Emily sitting on the outside of the vessel, looking up at the Earth and Moon; a panel showing the International Space Station with the arc of the Earth behind it. Dialogue continues over the top.)
Dee:
I knew about like, the gist of disease, and food, but I didn't know about ATP or enzymes or any of the actual chemistry.
Emily: Hah, did you used to believe in humours?
Dee: Hahahaha! No comment. But I'm pretty sure I learned about scurvy before I met you. Not everything is that recent.
Emily: Just nearly everything.
Dee: I'll give you that, heh. I sure didn't come up with any of this vessel on my own. I just adapted other people's inventions. Sometimes used their equipment, secretly.
Emily: Well otherwise you'd be reinventing the wheel, wouldn't you? This is what history is made of!
Dee: It seems like people sometimes reinvent a few wheels, though.
Emily: I guess. But mostly every little thing is made from cooperation, right? Working on making life a little easier, bit by bit...
Dee: Well aren't you a huge sap today!
