Now, Hermione Granger was a smart witch. Brilliant, even. But she always had a major respect for her teachers and believed that they were always right and could never, ever be wrong. So it never occurred to her that Albus Dumbledore shouldn't have lemon drops since he could get diabetes. After all, Dumbledore was always, always right.
Ronald Weasley was a chess prodigy, and therefore a genius at strategy and planning, not that anyone recognized it, but that was beside the point. Ron also had to think ahead a lot, so he would be horrified at the thought of an old man consuming mounds of sugar daily when it was his duty to mentor a teenage boy, especially when said teenager was supposed to save the world. But Ron was raised in a family where Albus Dumbledore was God, and could never, ever be wrong. So it never occurred to him that Albus Dumbledore shouldn't have lemon drops since he could get diabetes. After all, Dumbledore was always, always right.
Harry Potter was a very logical and to the point sort of boy. After all, he couldn't have faced Voldemort so many times and lived to tell the tale on just luck! So Harry became quick on his feet and gained a fast mind. For Harry, if you couldn't think logically then you weren't mentally sound. But sucking on lemon drops every single day when you had so many responsibilities wasn't logical either. But Albus Dumbledore was a mentor figure to Harry Potter, and was someone that Harry strived to be like. And Professor Dumbledore could never, ever be wrong. So it never occurred to him that Albus Dumbledore shouldn't have lemon drops since he could get diabetes. After all, Dumbledore was always, always right.
Minerva McGonagall was an immensely powerful and prioritized witch. She knew what was important and what was not, what was right and what was not, what was logical and what. Was. Not. But ever since she was a little girl, Albus Dumbledore was brave, and smart, and a savior, and he could never, ever be wrong. So it never occurred to her that Albus Dumbledore shouldn't have lemon drops since he could get diabetes. After all, Dumbledore was always, always right.
Severus Snape was a highly accomplished perfectionist of a wizard. He was the youngest Potions Master in the world, how could he not be brilliant?! As for the perfectionist part, potions required accuracy. Accuracy required logic. Logic required a sound mind. A sound mind required (for him at least) a code of responsibilities that you had and needed to prioritize above everything else. If it required your health, you would put your health above all other things. According to Severus's code, Albus Dumbledore should have done that. But it was Dumbledore, for God's sake! He was the Leader of the Light, and therefore could never, ever be wrong. So it never occurred to him that Albus Dumbledore shouldn't have lemon drops since he could get diabetes. After all, Dumbledore was always, always right.
Quidditch and wizard chess players required strategy and skill. Unspeakables required plans. Aurors required quick thinking. Non-Gilderoy Lockhearts required brains. Everyone should have known that Albus Dumbledore shouldn't be eating lemon drops, but nobody did a thing. Not even the Healers and Mediwitches and Mediwizards and the portraits of them for God's sake! Because it was Dumbledore. Albus Dumbledore. Albus Percival Wulfric Brian Dumbledore, and that. Was. That.
But what Albus Dumbledore never told anyone, was that he already had diabetes. Severe diabetes. And that he was going to die sometime next year. But he didn't want the Wizarding World to think that he was a lying bastard, because they would start to realize that he was a manipulative bastard as well. So, no. Dying from diabetes was not an option. So Albus Dumbledore started to explore options of how to die that fit his needs. It had to be painless, something that wouldn't be looked into too much, quick, and benefiting of his status. Albus Dumbledore was most definitely not going to slip in the bathtub and crack his head open, thank you very much. Then Albus had the brilliant idea of telling everyone that he was fine, but telling Harry and the staff that his hand got poisoned! Just a simple coloring charm on his hand and a confundus on Severus would work miracles! He truly was brilliant. But, hold your horses! Poisons normally weren't painless, so he wasn't going to actually digest one, that would be foolish. He was planning to tell Harry about the horcruxes next year anyway, and he knew where Marvolo's ring was, so he'd say that he wore the ring since it had major enchantments on it! Ha! And he could get Severus to murder him as well, say it was good for the Malfoy boy or something of the sort (since Draco Malfoy got told to murder him at the last Death Eater meeting)!
And that's exactly what happened.
But the story didn't stop there, oh noooo.
Harry got it into his head that all the horcruxes were poisoned.
And then Hermione told him that goblin metals were wonderful conductors of poisons, such as Basilisk venom.
And Basilisk venom mixed with most poisons was deadly.
And that Findyfire couldn't destroy poisons.
So it was a cold winter (late) night when Harry Potter said the V-word and the Snatchers showed up.
It was a cold winter dawn when they reached Malfoy Manor and Bellatrix Lestrange found the horcruxes they had, and placed all three of them in separate, high security, elf-blocking rooms.
It was a cold winter morning when Voldemort showed up at Malfoy Manor and decided to induct Harry, Ron, and Hermione into the Death Eaters since they obviously had brain cells.
It was a cold winter morning the next day when Voldemort took over magical Britain.
And it was a very cold winter morning the day after that when he started on the rest of the world.
And when asked in 2020, about what made Voldemort want to do it all, he replied:
#Slytherin for life
#Wanna be remembered
#Take that Dumbledore
That went down in the history books, trust me. Not that anyone read them, because, dude, Binns sucks.
