Consequences of Meddling With TIme

Hermione Granger is given a Time-Turner and instructions to use it. Only, using a Time-Turner can be a little tricky if not used correctly: a mistake made in counting or a slip of fingers can make the user jump irregularly and thus she could accidental alter her time line. And when such an accident happens, Severus Snape uses Hermione's Time-Turner in order to fix a horrific wrong.
