Mysterious thing, time... powerful, and when meddled with, dangerous.
Did you ever wonder how Albus Dumbledore was always capable of predicting things and acting in the way to make sure he's victorious, or at least has a chance to turn tables in his favor?
Some may think that this is just what experience and talent does to people, especially when it comes to powerful wizards. But one fan theory on Reddit offers a much more reasonable explanation: the Hogwarts headmaster was a time traveler.
Moreover, the theory goes on to claim that he abused his power "to go back over his life again and again, interacting with himself and telling himself things about what's to come", which resulted in "all the worst tragedies of his life."
According to the theory, first sign pointing at the possibility that Dumbledore was messing with time is how experienced he sounds when he hands Hermione the time-turner.
"The reason Dumbledore is the most powerful wizard in existence is because he has been doubling and tripling and quadrupling back on himself, giving himself extra time to learn and tutoring himself to exponentially increase the rate at which he learns. How do we know? Because this is precisely what he gives the time turner to Hermione for, to cram in extra learning," the theory implies.
Then, isn't it interesting how Dumbledore appeared to have known the cause of his death (essentially, he would have been killed by the ring's curse if it wasn't for Snape murdering him after all)?
The fact that he still made mistakes and seemingly wasn't immediately able to predict that Voldemort used horcruxes to sustain himself may also be pretty simple.
"Throughout the series there are multiple Dumbledores all existing at once, folding back over himself again and again, so that he can be in many places at the same time, and that the Dumbledore Harry and the others often speak to is from the future, and has already lived through the events of the story many times," the theory claims.
Essentially, we are talking about the multiverse — something that quite falls in line with J.K.Rowling's magical world.
Judging by how heartfelt Dumbledore sounded when he dropped his iconic quote on how mysterious time is in Prizoner of Azkaban, he is the one who should really know.
