One thing I would like to point out is that Elfman, Natsu, Gray, Cana and Loke are the same relevant FT members that were brawling the first time Lucy came to the guild. I even re-read chapter 2 just to double-check it.

It also has the Mirajane bottle scene that were mentioned by the other users here.
