Prompt: #39: “Time-travel/AU - Disgusted with Dumbledore's manipulations, Harry time-travels to the past and tells Severus EVERYTHING. Clever Severus changes history.” I also took inspiration from #18: “Harry uses a time turner to try to save Snape after Nagini's attack, but goes too far back and winds up at Hogwarts just in time for Severus Snape's first year as a professor.”
A/N: The primary storyline (Past Timeline) takes place in the months following the Battle of Hogwarts; Harry is 17-18 years old. The parallel storyline (New Timeline) takes place during Harry’s sixth and would-be seventh-year; Harry is 16-17 years old. All sex is consensual.
