After Erwin comes home from the brutal expedition to reclaim what they thought was a broken Wall Rose, Levi realizes that more has changed than just Erwin's physical appearance.
Weak and injured, Erwin has to come to terms with his new reality of no longer having his right arm. Will Levi be enough to help him? Or will the Commander if the Survey Corps loose all of his willpower?
