The End (possible spoiler)
Debbie was rescued after five years as a Comanche wife/woman/slave. She didn't seem to want to be, but her brother convinced her "home" was better, a home where she'd be a wife/woman/slave but that was okay because she wouldn't be a captive. You'd think in five years she'd have produced at least one child, but apparently not.
Would white settlers have accepted her as one of their own upon her return, or would she forever be seen as "tainted" and be an outcast? Did they live happily ever after, or was that just in Ethan's mind?
