I rather enjoyed this, I agree her being a Kenobi is much more powerful and heartfelt approach. Although I’m slightly jaded due the fact that I hate the idea of her being Luke’s daughter, the concept is hackneyed in my opinion, and honestly just plain boring. Plus, and maybe I’m missing something here cause I’m yet to see anyone bring it up but, Rey is waiting for her parents to come back… so she must remember them leaving her there for whatever reason, so wouldn’t she recognize her father? Granted they could be fosters, but you would think Jan and Leia would have known if Luke had a kid.
Anyway, what I really wanted to say was about Obi Wan and him being incorruptible, although he is basically the perfect jedi in episode 3 we do see him falter. Jedi are suppose to abandon all personal attachments and concepts of love. In the final showdown Obi Wan tells Anakin he was his brother, albiet figuratively, and that he loved him. So in my opinion it’s not all to hard to believe he didn’t foster a child.
Another interesting thing, all though far fetched, comes from some stupid thing I read about how to making watching the prequels enjoyable. It was to imagine that Amidala and Obi Wan were having a love affair. Which seems laughable, but if you watch them in that mindset you can see it, and it actually adds a very dark underlying plot to the film’s. Like I said far fetched but it does show evidence that Obi Wan can’t entirely block out love.
