"had this new guild always existed" What new guild?

I don't see why Gajeel should have bothered to show the twin dragons the graveyard. Telling them about it maybe, but does even that matter much?

I don't think we'll see any information about Zeref revealed untill short before the final battle (as in the very end of the manga).
