Of course I do believe youBut since you're mentiong Poe... I honestly think people don't pay much attetion on him, becouse "he was suppose to die".But in my opinion, he's much more instrumental than he seems.If we pay attention to the early drafts of the movie, many things have changed.one of the sources if you or someone else want to know more http://www.slashfilm.com/force-awakens-changes/ In few words, I don't think Poe was "Jhon Doe". Jhon Doe became Lor San Tekka and when theyìve decided to let Poe live, they used for his charater some ideas they've already developed for Sam that at that point was already Fin.I'm saying that becouse I think Poe's interrogation (like almost any of his lines in the movie) is one of key of the mystery box (or boxes).I have a different idea than yours (as you've probably know now) and I don't want to abuse of your work here to talk about my speculations.I'm adding this, just to explain better what I've already said: I guess you're focusing on many things people don't and you're right on doing so, plus lots of the symbolisms you've noticed are very interesting... even if (at least to me) they may led somewhere else.
