Well i'm actually very interested in the Lucy kneeling before Zeref thing, maybe it'll turn out that Future Lucy works for Zeref. Then "someone saying she will never meet Natsu again", might be Lucy, or like you say Mashima decides to explore bits of Natsu's history. Raven Tail member being Arcadious's spy, this plot seemed to have disappeared. A farewell to Jellal, it seems like something Mashima planned for a long time but can't find a correct moment to do so, ironic considering that Mashima created Jellal because he regretted killing Sieg Hart but then maybe Mashima likes to killed tattoo-faced men.
