Well if they are, one might presume that while Luke was training Kylo, he was simultaneously raising Rey. If Kylo turned over to the Dark Side it would probably have ben in early teens at the earliest, and thus Rey, who is approximately the same age, should be able to remember Luke as her father.

Unless Luke decided to leave Rey on Jakko as a child and then resume the training of Kylo for another 5-10 years? But then it doesn't makes sense that he would leave Rey for fear of her turning over to the Dark Side like Kylo, as that would not have happened yet.

Am I missing something or does it make sense?

I'm very aware, and a straight female. Sooo thanks..for reminding me xD
