There’s something I find interesting about Rey. Due to the environment she grew up in, it just adds more to why she’s so great with the Force. When comparing to Luke’s beginnings, Luke has this impatient vibe and a little bratty. Now, hold your horses here, I actually find Luke relatable; being stuck with family and wanting to be somewhere away from home. So again, I have no issue with Luke here, just making this clear for what about I’m about to say.
Rey is basically a toughened up person by the time we meet her. She also exercises key Jedi traits, such as patience, something Luke struggled with for the first two films. Unlike Luke, Rey had no home to come to with someone that cared about her. She didn’t live on a farm where food tends to be plentiful. She instead spent so many years scavenging for a living in order to survive. She stayed on Jakku out of choice because she willingly wanted to wait for her parents to come back, even though day by day (and she literally counted those days as we see in the film), it was unlikely to ever happen.
This is why I’m not really all that disappointed that she had a more tuned relationship with the Force once she understood it IS real. She was able to calm her mind (something Yoda insisted Luke should do) when the time came and it was believable to me due to her upbringing. I’m not saying by any stretch that Luke had a rich and easy life, but in comparison, Luke was living in comfort on Tatooine vs the battle scarred graveyard planet of Jakku.
So essentially Rey was initially trained in the force at a young age…said training remained dormant…but her bare and meager existence upon a treacherous world allowed her implicit training in its usage during her intervening years awaiting the return of her family…?
It is a possibility…indeed a potentially plausible explanation…although I suspect it not to have been at all officially considered. Still, it bears pondering…
