Potential Rey movie spoiler tag, my bad:

If the longstanding rumors of the Rey movie are to be believed, it’s understood that Rey will become pregnant by Ben despite the fact that he’s dead. Perhaps they’ll say she became pregnant when Ben poured his life essence into her. This would make sense because the camera lingers on his hand being over her stomach. I’m bringing this up because this whole Rey Chosen One idea would neatly align itself with what’s to come, given that Rey would be conceived of no father, herself. Ben would be doing the light-side inversion of Palpatine bending the Force to his will to create life such as Anakin and Rey, because Ben actually gives up his own life to create life. So while Anakin and Rey are genetically unrelated to Palpatine, Rey’s child(ren) would be authentic/genetic Skywalkers.
