Was this the first time we've seen Lucy drink alchohol? I can't remember.
Not much to say about the chapter, the old joke about the master is so old that not even the mangaka repeating the joke seemed to loose motivation in telling it.
Well hopefully the flashback with be interesting, though I don't know if it will be a long one as we already got Zero tell us the history of Mavis and Zeref's first encounters, and we got the history of him recreating(?) Natsu. So this would be the time inbetween, where they met each other again, unless we get a flashback within the flashback to explain the history of Acnologia as well.
I guess it all depends on how much of the history we get, will we get the history on how Natsu ended up with Igneel?
