As an audience member I’d have a lot of questions about why they’d be assigned to raise and kill a child, as that phrasing makes it sounds like a single overall assignment.
And I still have a hard time getting over that Rey’s mother looks just like her.
I agree with the first point. Currently trying to find a way to make it sound like there was a change in their directive after a few years. That’s what the next line should imply “But they’d grown to care for you…”
I can fix the second point quite easily. Deepfakes have become easier as of late.
