I'm not aware of an explicit answer in the movie or the novelization, but it seems pretty self explanatory to me:
Rey is an orphaned, impoverished scavenger who lives a hand to mouth existence. She probably doesn't have many clothes to begin with.
She leaves her home on Jakku suddenly and unexpectedly, and doesn't have a chance to pack a change of clothes. ...
She was reaching out to a man who had shut himself away from the galaxy...
...by giving him something that he has a personal connection to — his long-lost lightsaber.
Even if she was aware of a fine detail such as his newer green lightsaber (and there's no reason she would know something like that when it's clearly established in The Force Awakens ...
It was 100% Kylo Ren.
When Snoke was slain, Rey had her back to him and when she turned around to see what happened, she was in complete shock.
Also, Snoke narrated Kylo Ren's thoughts, which included him (Kylo Ren) striking down his enemy.
Lastly, Kylo Ren lied about who killed Supreme Leader Snoke because it would be considered treason, and Kylo Ren ...
First of all, Rey offering Luke her weapon shows that she means no harm. But there is much more significance to offering that particular weapon.
The lightsaber belonged to Luke's father before him. It is the only memento he ever had of Anakin Skywalker. It is an object of deep personal significance, and (so far as we know) he thought it was lost forever in ...
The helmet belongs to a rebel pilot called Captain Dosmit Ræh, a member of an elite fighter squadron called the Tierfon Yellow Aces, hence the instantly recognisable yellow sigil.
Her X-Wing, (callsigned 'Yellow-4') crash-landed on the planet during the Battle of Jakku and was salvaged by Rey along with a variety of survival gear items found in her ship's ...
There are a whole bunch of reasons why she decides not to sell him, at least according to the film's various novelisations.
She clearly feels an affinity for him
Rey had been teasing the little droid, but his response caught her completely off guard.
“You’re waiting for someone….” Rey glanced over at the spaceport. Every day, whether she admitted it to ...
She picked it up by interacting with offworlders.
According to Pablo Hidalgo’s TFA Visual Dictionary (which is canon):
Rey’s interaction with offworlders has allowed her to learn nonhuman languages such as Wookiee and astromech binary.
Props to @DVK for finding this, as seen in this answer on another site.
There are several hints as to her lineage. But nothing for sure.
There is also a lot of imagery linking
Now this could all be misdirection, but I think it is what we are meant to believe after seeing the film.
From the novel:
Kylo seems curious as to this girl, from the outset. However when questioning her he decides
Even in the ...
My take on it at the time was that she didn't regard BB-8 as being her property in the first place -- so she had no right to sell him to anybody else, in the second place.
Remember, they first met when Teedo had captured the droid in a net, and Rey vigorously objected, apparently because she felt there was something morally wrong with the situation. If she ...
The canon answer (offered by the Force Awakens: Visual Dictionary) is that Rey was simply too busy saving the whole.damn.galaxy to think about changing her outfit. When she arrives at the Starkiller Base she briefly borrows Finn's jacket (seen in the deleted scene pictured below) but just shrugs off the discomfort in order to get on with her mission.
Rey gave Luke the lightsaber, but she was not:
searching for Luke Skywalker to give him his lightsaber
She had it, and she was looking for him, and it was his, but they don't flow in the order you're suggesting. She was looking for him for training; having the light saber was incidental.
Didn't she just know that he already got another one?
In the ...
Finn has apparently had access to entertainment programmes (of a historical nature) as well as the more mundane First-Order weapons and tactical training.
As madness ebbed and surged around him, he wandered through the
village, feeling himself more a participant in a historical drama than
in an actual battle. The horrific and all too common red stains ...
I didn't see any evidence in the movie that suggests who her parents really are. The two theories are Han and Leia, or Luke and "someone."
You listed one point about Luke's lightsaber that could suggest a tie, however the end of the movie suggests an even bigger possibility:
We don't ever see a Jedi show that kind of emotion anywhere in the movies. Now, ...
From Rey's Story
Absentmindedly, Rey mimicked the mother’s loving gesture, softly
stroking the salvage in her hand. Rey had no memory of her parents.
She didn’t know why they had taken her to Jakku, or why they had left
her there. For all she knew, they were long dead. Yet Rey couldn’t
help hoping that one day a transport would arrive and her ...
Latest update: (2016/01)
There's still no canon information (for a good reason) but Star Wars: Episode IX director Colin Trevorrow told Entertainment Tonight regarding the theories:
“I’ve seen all of the theories… What I do know is that we’re going to make sure that that answer is deeply and profoundly satisfying, because Rey is a character that is ...
Leia ordered her to go to Ahch-To to find Luke Skywalker. Rey feels that the Force is guiding her and that her decision (to go) is the right one.
Rey headed to the launch area with R2-D2. Leia waited near the boarding ramp. She adjusted the fit of the new flight jacket Rey wore. “I’m proud of what you’re about to do.”
Rey looked into Leia’s eyes and saw ...
As of the end of Episode 7, there is no romance between the two.
John Boyega (Finn) cleared this up in an interview with Variety when they said they liked the romance between the two.
I loved the developing romance between your character, Finn and Rey in “The Force Awakens.” How is that romance evolving in the next chapter?
Boyega: I mean, we didn’t ...
Well, there are speculations that Rey is Luke's daughter... You might be able to infer it from how strong Rey is with the force. In the trailer, Luke says that the force runs strong in his family: His father, his sister, and himself. And he seems to be talking to someone, saying it runs in him/her as well. That's why Kylo Ren was so strong: because of Leia.
According to the Alan Dean Foster's TFA novelization, he desperately wanted to find people (because the planet was a very unhospitable environment for him).
Contrary to much popular thought, desert worlds are not quiet at night. In the absence of light, an entirely different ecology springs to life. Moving with greater caution, BB-8 tried not to pause at ...
In the book Aftermath: Life Debt, it is explained that despite Han seeing and treating Chewie as 100% equal to him, while on Kashyyyk, he tends to let Chewie take the lead.
Given this change of dynamic, it's not unreasonable that the Wookiees might assume that Chewbacca is the captain and Han is the first mate.
Working with Solo on this has been ...
Specific to the source of this supposed rumor—the Disney Infinity game for The Force Awakens—this is a solid “No!” according to this article on Kotaku:
Only he doesn’t call her “cousin.” As Angry Joe later realized, hence
the removal of his video, is that what Kylo Ren is saying is “Face
me!”, which is quickly interrupted by “Curses!” when he suffers
Because it belongs to him.
His father built it; he inherited it. Despite Kylo Ren's insistence that it belongs to him as some sort of heir to Vader's legacy, (which the light saber itself refuted by responding to Rey rather than to him when they both reached out with the Force to take it) that light saber belonged to Anakin Skywalker. Vader's light saber ...
The factbook "Rey's Survival Guide" strongly implies that she learned to speak Wookiee using the computer language tapes that she found during her salvage of Rebel ships, in much the same way that she learned to speak droidspeak.
What do I do when I'm home? Mostly, I refurbish gear at my workbench - it costs too much to make extensive repairs at Unkar's
No one knows.
That was the entire point of the writing choices for that scene.
Rey: "Tell him...." (pauses to think, unsure)
Chewie: (something no one in the audience can understand)
Rey: Yeah, perfect. Tell him that.
If the writers had been able to think of a really good line to put there, maybe they would have.
Instead, they made it a ...
This is apparently covered in a large deleted scene which includes Rey running down a beach with the lightsaber ignited. I'm not sure how true it is but I've seen numerous articles claiming the same. In short the third lesson is:
A true Jedi will only act to maintain balance.
Here's what the article has to say in full including some reasoning behind why ...
Possibly, but there's not much evidence
In The Force Awakens, Rey and Finn have only known each other for a few days. It's therefore unlikely that they have extremely developed feelings toward each other, though this may happen in time.
However, at the end of The Force Awakens, Rey does kiss Finn on the forehead.
A NEW DAY.
Finn, unconscious in ...
Any familial ties between Rey and other characters have yet to be confirmed.
J.J. Abrams did release an answer to a young fan back in April of 2016, stating:
"Rey's parents aren't in Episode VII. So I can't say in this moment who they are. But I will say it is something that Rey thinks about."
J.J. Abrams later restated this remark later on:
