Another theory that hinges on the connection between Luke and Rey postulates that their relation is not genetic, but a closeness borne out of him being her Jedi teacher early on in life. We know that Luke was leading and training a new era of young Jedi before Kylo Ren was seduced to the Dark Side and slaughtered them all. Was Rey one of them? Did someone help her escape the First Order's wrath by hiding her on the desert planet of Jakku in the same way Luke was sent to Tattoine as an infant? In the flashback showing a young Rey, we see her sadly looking up at what we think is her family's spaceship disappearing into the distance while she's left behind with someone (something?) just out of view.
Is her "family" actually just fellow Jedi students who luckily escaped Kylo? Is it Luke? We can't know for sure, but one thing to remember is that during Rey's chat with Maz Kanata, the wise, old alien tells her, "Whomever you are waiting for on Jakku, they're never coming back."
Likelihood that Rey is Luke's former padawan: ⭐️⭐️⭐️
