In the movie, Rey's past and her possible relationship with other characters is left vague, though there are some hints that she
is a Skywalker.
However, there is a rumor that in the Disney Infinity game, Kylo Ren calls Rey his "cousin".
Is that true?
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 damage.
This is the video that started this whole rumor storm:
And this is the video the author of the Kotaku piece made of his own gameplay to confirm that the character simply says, “Face me!” and then “Curses!” after he incurs damage:
At present level of canon (December 2015), nothing definitive is known about Rey's parents. There are several canon hints (which may or may not pan out to be misleading vs true); and even more fan theories. None of them have any definitive canon confirmation, and likely won't till at least Episode VIII
Where we find out that Luke and Leia are Rey's parents, tapping into Game of Thrones fandom, tying up unresolved storylines from Episides IV and V, and neatly uniting all the best fan theories. JUST KIDDING!
Other theories include:
* Luke (based on anvil-strength hints in TFA) and unknown woman (presumably, CORE world resident based on Rey having British accent and a theory that in almost all roles, that maps to Core - vs American accent for Outer Rim);
* Han and Leia
* Han and unknown woman
* The Force (the way Anakin had no father, except NO MIDICHLORIANS!)
* Some other unrelated people
Specifically to address the rumor you alluded to, it was later updated and confirmed false by the same person who originally started it. Kylo says "cursed", not "cousin" in the game.
