I'm going to be over here working on my forty minute Youtube conspiracy video about how Qi'ra is Rey's mother and Jin Erso's sister and maybe Leia's body double. I'll let you guys know when it's ready.
You might be onto something here; I'm assuming Qi'ra is pronounced Kira, and that's what Rey's original name was in the drafts and concept art of Episode VII:
There's also this, she was going to be paired with some young Han Solo kind of figure, is it just coincidence that they're reusing that concept? Is it also just coincidence that Rey inherits the Falcon? I think she might be Han's illegitimate child at this point. I hope she is. That handwave in Episode 8 was terrible, I want her origins to have significance, not just have her parents be drunks.
However bad this movie is, I'm looking forward to it more than I did with Episode 8, and I certainly pray I enjoy it more.
