Uninteresting octopus fight, thankfully the rest of the episode was good...minus the jiggling parts
So, we finally get an idea of what this whole crusade is about, it was high time some light was shed on the plot. I like the way this is going, it seems like part 1 of the filler arc is over (gathering the clock pieces) and we'll be heading to part 2 (averting the destruction of the world, duh :P).
Good OP/ED, Erza's rapeface deserves a mention.
