If your twin died, and you had a chance to go back in time to fix that, wouldn't you? even if there was a chance of you getting hurt. Well George Weasley is at the Ministry of Magic, helping his younger brother Ron, when he sees a shelf of time turners, he grabs one before someone sees. Follow George as he tries to save Fred.
sorry if somethings don't follow the original books plot, it's been a while since I've read the books, also I own none of the Harry Potter characters.
