There is something very clear in the sequel trilogy about Rey that many people do not see at all. One of the reasons why Rey may be really good at accomplishing things is because of the way she grew up. Even though Unkar Plutt took her in when her parents abandoned her, she was still practically alone, as she had to hunt and work for her own. She worked for Plutt, earning her own food, and scavenging old ships by herself. Plus, she is experienced in melee combat due to her years of using her quarterstaff. Luke, on the other hand, grew up under strict requirements from Owen and Beru as a farm boy. He wasn’t allowed to go off on adventures out in the Galaxy and this is why he felt that he was going nowhere. Rey, while it wasn’t as strict for her leaving, still had a job to do, which was why she had to stay there. That’s they filmed a scene that got removed of Unkar Plutt finding Rey at Maz Kanata’s castle. Also, she stayed on Jakku because she was waiting for her parents. Each tally in the AT-AT she marked was a day she waited for her parents to come back.
