The Potion Master's Apprentice (слэш)

Severus Snape didn't know what was going on with Harry Potter. One minute he was having a fit and spending a day in the Infirmary, and the next he was gone. Three weeks later, he witnesses the boy miraculously reappear and slay the Dark Lord. Now he's sitting in Albus Dumbledore's office listening to the boy claim he's from the future, master of death, and leaving. But of course, Albus insists on other options. Snape finds himself landed with a boy who isn't the same boy Severus knew.
