"'What were you doing there Engine?'
'Eh, just taking a stroll.'"
Seriously hoping this series actually develops their characters and lore, because the world building has so much potential. Along the things I'm hoping for, mark down Engine playing his cards close to his chest and having some secrets going.
"Isn't anyone up there aware of this? Or did they knowingly dump junk and people here?"
Seriously. Potential. Let's this be foreshadowing, and not just a throwaway line, PLEASE!
