3. Rey is suspiciously good at flying and repairing things, not to mention Luke’s lightsaber calls to her.
Considering we never get to know her parents, there is a lot of room for speculation on the matter. Rey is really good at fixing things, even putting Han to shame when it comes to fixing his own ship. Can we think of anyone else great at fixing things? Hate to bring up prequels but Anakin was pretty awesome at that, having built R2-D2 and C-3po and what not. Also, Rey is a great pilot like Luke and Anakin, but we learned that could be from her abilities as a force sensitive. When you factor in Luke’s lightsaber calling to her, there’s a real case that Rey is the daughter of Han and Leia and Kylo Ren’s sister and they hid her once he went bad. Unless Luke was doing more than just looking for the original Jedi temple, this little hints might lead to something real.
