They inserted that dream sequence and scene with Erena and Mikasa so they could drag things out and end the episode on that scene with Mike.What was dragged out here?
It's the exact same problem as with the first series: they're going to regularly drag things out so the episodes (and cours) end on specific points. I get where they're coming from, but clearly, the 24 minute/episode and cours formats don't agree with the source material.
