I can’t understand why so many of you have a problem with Rey being a Palpatine. For me, it’s the only possible explanation why she is so powerful. I like the character of Rey, but in Part 7 & 8 it always bothered me, that she was too strong and powerful. But when it became known that she’s a Palpatine, everything made sense to me.
But why is Palpatine so powerful? If it’s genetic, there’s no reason Rey couldn’t have been born with the same random innate power as young Sheev. If it’s from years of intense Sith training, then Rey wouldn’t have inherited it.
Why is Luke so powerful? Because his father was. Why Leia and her son? I think it is genetic. It does make sense to me. It doesn’t have to make sense for everyone else. But when I saw the movie the first time, my reaction was “OK, that explains why she is so powerful and why she went straight to the dark side in TLJ”. The whole trilogy would have been much more implausible for me when she would have been a nobody. But thats just my opinion.
