....Could've Hermione used the time turner to go back in time and stop Tom Riddle? (i don't know how far in time a time turner can go but if it could've gone 50 years back in time than....)
With her Time Turner, no, at least not without ending up like Eloise Mintumble.
Or she would end up like Snape in "How Harry Potter Should Have Ended ?" ^^
PS : It's the first video.
What do you think?
