From what I read on tumblr the literal translation of the next chapter is - If a fish is kind to the water, the water will be kind to the fish (or stuff like that). It's a Japanese saying which means that if you done someone a good deed, that person will repay you with a good deed aswell. Something to think about.

I think the Arc is coming to an end, Mashima said it himself on twitter not long ago. All that is left is to beat Mard and stop Face. Probably there won't be a part 7, or we will just see a few chapter long epilogue. As for E.N.D. due to some plot device he will either stay sealed, turn out to be harmless for FT or just disappear with his book, something that will also cause Acnologia to fly away. Something like Galuna Arc, everyone was thinking the last fight will be with Deliora, but it ended without it.
