Is it possible we need to look closer at Obi-Wan's demeanor at the end of ROTS? I'm sorry, but he looked eager to the task of taking Luke and even perked up when Yoda mentioned communing with an old friend. So in 10 years nothing? Just a shell of himself and " I'm not who I used to be" ? Nope...he's just gonna sit around and mope, not train, no force use...sounds like a great plan to protect Luke. The more I think about it, the more it makes no sense. Meanwhile, " another Jedi" seems to have grown a bigger backbone and Obi-Wan doesn't sense his presence but he senses Obi-Wan's...what?...if he is closed off from the force, how does that work? Reva can pull a Kylo force mind read on the fake Jedi but says , " I won't try that on Owen Lars, I'll just act real tough and maybe he'll cave. You know what, I need to cut myself off from the force of thinking about this and then maybe it will all just make sense somehow .
