After Hannes is eaten by the Titan which killed Eren’s mother, Eren suddenly unleashes an incredible power upon the Titan, causing the other Titans to swarm it and tear it to pieces before chasing Reiner and Bertholdt away. For her own reasons, Ymir leaves the Scouts and retreats with the Warriors.
The Scouts later conclude that the Titans which invaded Wall Rose were in fact, the human citizens of Ragako. As Eren devotes himself to discovering how to use his newfound power, a recovering Erwin concludes that the truths of the world will soon be known.
