You were sitting in potions class with everyone else as Professor Snape walked in he first asked a question. Snape: Does anyone know what a reality shifter is? Hermione raised her hand. Snape: Granger? Hermione: Reality shifters are people from a different reality who shift to a chosen reality to live out a bifferent life but... they are just myth... right? Snape: Wrong. You felt a slight tinge of guilt in your chest.
