Details From Harry Potter and the Cursed Child That Make No Sense
Why Did Cedric Become a Death Eater Again?
According to one of the alternate timelines that Scorpius and Albus create, Cedric Digory becomes a Death Eater because he’s humiliated in the Triwizard Tournament. As a result, Voldemort defeats Harry and goes on to reign for years. This is all because Cedric killed Neville, so Nagini remained alive and well during Harry and Voldemort’s final duel.
The problem, of course, is that Cedric’s reasons for becoming a Death Eater seem pretty thin. After all, if being humiliated once can turn anyone evil, then more of us would probably be going around murdering people. The Cedric we knew was a fundamentally decent guy. He wasn’t one incident away from fascism.
