Thanks for returning for the conclusion to my Rey lineage theory. If you missed part 1 you can find it here.
Now that you are back, we better jump into the Millennium Falcon to continue our journey.
Speaking of that piece of junk, Rey immediately insults the Millennium Falcon... just like Leia did when she was astonished that Han, Luke, and Chewie, "Came in that thing? You're braver than I thought."
The Millennium Falcon provides many pieces of evidence that Rey is Han's daughter. First, after about 10 seconds to get familiar with the ancient ship, she flies it perfectly. Part of that may be due to her Force ability. But to me it seemed like it was like riding a bike to her. She had seen her dad fly the ship as a child. Perhaps she even got to take the controls (that seems like something Han would have done).
Not only did she fly it well, she flew it just like her dad would have. Her maneuvers through the crashed Star Destroyer reminded me of Han's flying through the asteroid field... and then escaping from the space slug. After the escape, Finn asks her how she did it. She excitedly responds, "I don't know". She just did it naturally... like she had done it or seen it done before.
Not only does Rey fly the Millennium Falcon flawlessly, she does it without a copilot!
Later when she is repairing the Millennium Falcon, Rey tries to get Finn to provide her with the correct part. She has to repeatedly correct him. This seemed very similar to the scene in Empire Strikes Back when Han tries to direct Chewie on how to fix the Falcon by scolding, "No this one goes there. That one goes there!" In fact, Rey's fixing the Millennium Falcon was reminiscent of many scenes of Han working on the Falcon.
