If Rey is a Skywalker

If Rey is a Skywalker you and me are gonna have problems. (I know I don't look like Daisy Ridley but I think my Mark Hamill's on point) The idea that LST is there to watch over Rey was first suggested to me by redditor StornZ and I'm worried it checks out. For real if her parents are not dead or physically being help captive they are ruined for me and it better not be Luke or Leia. (I haven't read Bloodline yet but from what I understand it debunks the popular Rey Skywalker timelines? Ben defected way after Rey would've been left on Jakku so she couldn't have reasonably been Luke or Leia's child. I don't know.)
