9 Harry Potter Plot Holes That Actually Have Simple Fixes
3. Why Are The Dementors So Into Harry? - The Prisoner Of Azkaban
Plot Hole: Dementors are a terrifying thing, they suck away your happiness until nothing is left but your soul; and then they suck that out too! Alfonso Cuarón successfully created a horrifying monster that has stayed with and haunted HP fans for almost a decade and rivalled the initial disturbing description from the beloved novels. Thank God us muggles can't see them!
After the dementors set their sites on a vulnerable Harry for the second time in front of his peers, leaving him humiliated, Professor Lupin comforts Harry by telling him that Dementors are attracted to people with dark pasts.
That might have been enough to placate our hero, but we were all left still wondering. Is Harry's dark past really the worst of all people that are homed at Hogwarts Castle? What about Neville Longbottom? Or Luna Lovegood who witnessed her own mother's gruesome death as a child? What about LUPIN?
Yes it makes sense story-wise for Harry to be the focus of the Dementors torment as our main character, but realistically Lupin's explanation is a little lacklustre.
Answer: The Dementors are not attracted to Harry's dark past, but are actually sensing the piece of Voldemort's soul that lays hidden inside of our young protagonist.
It makes complete sense, after all: the Dementors are sent to Hogwarts with the instructions to protect the students from evil. Of course they would be able to sense Voldemort inside of Harry.
If only the Dementors could speak... maybe Voldemort wouldn't have been able to return from the dead if people figured out he still partially existed inside Harry. At the very least one Horcrux would have been destroyed.
