We're all total nerds and there's nothing we love more than to absolutely dissect a movie. In that vein: Rey's got to have a family, even if they don't come back. Who are they?
First, some notes I took at the second viewing:
- The transport flying away in her flashback looks like First Order
- She was sold to Unkar Plutt, the fat guy who owned the Millennium Falcon
- Kylo says Luke's lightsaber belongs to him, probably thinking it's his inheritance.
There's four options I can see on the table for Rey's parents: Luke/(someone), Han/Leia, her being the result of force experiments, and no one we know.
No one we know.
Boring. Next!
Force Experiments:
Unsure, need to read more. Speculate away in this thread.
Han/Leia:
I haven't read TFA novelization, but I've heard it talks a lot more about Ben Solo, and there's no mention of a sister. Additionally, I think Leia would be aware of her giving birth to a daughter and there's no recognition from her or Han when Rey is around.
Things in favor of Rey being Luke's kid:
