Who says this to whom in which story/book?"You're on your own now, boy,"
optional bonus question for 1/2 sherlock:
Where exactly is this said?
Added note: I mean the geo- or astrographical location.
Hint #1:
Miles has nothing whatsoever to do with it.
That narrows it down quite a lot, I think, considering that eliminating all chapters/paragraphs about Miles halves your search volume.
Hint #1A: Actually an answer to Voralfred's question
It was said in the Nexus, which eliminates the Chalion and TSK worlds, and Renaissance Earth. Also not on Kibou-Daini I assume, unless the exact same sentence appears in Cryoburn too.
One quarter the volume.
Hint #2:
I'll narrow it down to roughly one eighth. The person speaking is male.
This statement does not exclude Betan herms, but it does exclude Cetagandan Ba and TSK's mudmen and maybe some of Ryoval's creatures.
Hint #3:
It was said downside, not in a space station or a ship or the void.
Hint #4:
It was said to a dumb person, in the sense of "unable to speak".
