J.J. Abrams debuted a never before seen clip about the final episode on The Tonight Show. The clip shows a snippet of Charlotte having a conversation with Ford.
Charlotte is trying to push Ford out and tells him that he will retire after revealing his big narrative. Ford asks her if she's worried that he will destroy everything if he leaves. She tells him that she knows Ford and he won't do any such thing....It doesn't seem to me though that Ford will go without a fight.
