Not to mention people should stop taking a character's belief or comment so literally.
Afterall, Princess Leia's message was "help me Obi Wan Kenobi, you are my only hope." Yet that wasn't true, since it was Luke, not Obi Wan, who rescued her and blew up the Death Star.
Yet people seem to have so much trouble getting it through their head why even though the Exile is referred to as "the last Jedi", that doesn't mean it's an error when it's proven he's not. <_<
