OK, brace yourself. You're going to seriously doubt your "HP" detective skills after this one.
*Light spoiler alert. You really should have already read the books by now, so it's not a full-on spoiler alert, but it's still something. Seriously, what are you waiting for? It's 2016; you have no excuse to have not read "Harry Potter" by now. That's like not voting or getting your driver's license.*
With the exception of Jesus' death in the bible, Dumbledore's death in "Harry Potter" is maybe the most important literary death to ever happen. It shook us to our core. For a lot of us, it was our first real brush with death, and for most of us, it was the first time something we really did truly love passed away.
The screwed up thing is that Redditor upyourjuicebox thinks it was foreshadowed earlier in the book series.
This fan theory is so obvious, you'll be scratching your head as to why you didn't see it earlier.
IT WAS RIGHT THERE THE WHOLE TIME! Trelawney's freakouts were throwaway moments more than anything when we were first reading the books, but in retrospect, they held significant weight to later events.
Was this one of those times Trelawney was onto something?
