I read many TFA rumours and watched many TFA Spoiler videos that fed me bullshit that I don’t believe any of this. It’s just click bait crap. Take this video for instance: https://www.youtube.com/watch?v=xul_XYOZXyo
But that’s jut one example, I’ve read articles about how Luke went into exile because he felt too evil/powerful. It’s all bullshit, all of this will go away eventually but for now we have to deal with it.
