[ Well, it can't hurt to explain more. In fact, Rey seems surprisingly unemotional about the whole thing. She has many open wounds, but this isn't one of them. The empathy she feels for them is too considerable, particularly now that she's left the planet and has a better idea of what it's like out there. ]

Jakku's one big desert, see. If you want to have anything to eat or drink, you need to scavenge something to trade from the ships that crashed there. I found one that I could get going again, but I needed their help—not just to make sure other scavengers didn't loot it while I was asleep, but to haul the parts we needed from other ships and keep finding enough parts to trade for food while we were working on it.

I wanted to trade it once we got it ready to fly—we'd have gotten so much food for it. But they only wanted to leave. So they took it. I stayed on Jakku, and everything went back to normal. So you see: I was no better or worse off for having trusted them.
