Why would little Rey be crying for her kidnappers to come back? And why would she spend all those years on Jakku waiting for her kidnappers to return for her? Does she suffer from some kind of chronic Stockholm Syndrome where she keeps getting emotionally attached to those who take her captive against her will? It would explain why she seemed to develop a thing for Kylo, I guess.
Whoever left her in the possession of Unkar Plutt would know that he'd treat her like crap. Two scenarios: 1.) If it was her parents, they were jerks . . . but kids may still want their parents, even when they're jerks. 2.) If it wasn't her parents, whoever it was were still jerks . . . and she wanted them back, even enough to be pining for them years later. Which of the two scenarios makes more sense to you?
Still missing the point. Kidnappers are often people the kidnapped person KNOWS.
So , imagine this (totally hypothetical imaginary story I created)
Rey , having been born of the other ....other ....twin sister, (because Leia was not the twin hidden off in ROTS, but truly a Organa, and force user, ) is raised in secret just like Luke was. Except , she is being secretly watched by A person who know the power she may contain, and does not want her to fall into the hands of the Sith or the Jedi as they have been the constant antagonists of all the major wars and suffering for the past years.
Upon learning that Rey is a Skywalker and will become a powerful Force user (maybe she makes fruit fly to her mouth or makes mops move to her hand unknowingly) , this watcher , Whom Rey KNOWS , as a friend and trusted Nanny, Teacher, gardener or mailman (doesn’t matter), kidnapped her and leaves her on Jakku, hoping she will be killed or forgotten (perhaps they care about he just enough to not want to kill her themselves)
Rey, being young, doesn’t remember this person as her parent, because thats never said.
All this joking aside, it was someone she loved and trusted , perhaps someone involved with her family, but not her parents.
Why? 3 ideas.
1. They were afraid of her powers and what she could become.
2. They wanted to Force her powers to manifest though stress and trials of life ( like Leia , some Force powers manifest during life struggles)
3. They were saving her for later, to rise to the challenge, like a good dessert you just cannot finish
