A surprise is lurking around the corner for Snape just after the war. It had been a year of pure struggle to overcome the pain and healing that was needed to recover after the war. Despite Snape wishing that he had died he somehow did not. When he returns to work, back as a defence teacher and the head of Slytherin, the walls of Hogwarts finally gives back but it isn't how he expected. Resentment was evident but headmistress McGonagall forces him to keep going. To push until there is nothing left to push.
