Do you mean a top-tier Dark Arts master, known to the world as the Dark Lord, so feared that even speaking his name sends shivers down spines, will be defeated by a little wizard who probably just graduated from a vocational school... or might have even dropped out in a few years?
Or killed?
Moreover, this Dark Lord has many minions, backup plans, and immortality methods similar to a Soul Artifact?
"..."
Wow, Voldemort really is a rare gem... ahem, character.
Of course, knowing very well that I am actually in a world of stories, even though I don't know much about the original plot, William is quite aware that this prophecy is most likely true and probably the connecting line of the whole story, but at the same time he clearly understands—
There should be no character like him in the original story.
And after I completely intervene in the main storyline, the growth and processes of these people will likely deviate significantly—so, an outdated prophecy doesn't really have much reason to be believed, and of course, Dumbledore clearly doesn't know this, William has no plans to tell him either.
After all, the goals are the same, both for the protection of Hogwarts, just one for the sake of the school itself, and one for the power beneath the school.
With the goal aligned, William didn't plan to argue with him over unimportant matters. After all, the other is over a hundred years old, and respecting the elderly and cherishing the young, most of the time it's not difficult to go along with the grain.
In the initial discovery of being within a story world, William had a sense of separation from this world, and his purpose for staying at Hogwarts a hundred years ago was merely to wait decades later to see if he could blow up a nice little day with the Secret Vault—
Otherwise, when defeating Lanlock at that time, directly swallowing the Secret Vault and achieving my own power wouldn't it be better?
Just in later research, William found himself seemingly trapped in the pursuit of power, so in his last school year, he put aside most of his Ancient Magic research and started often going out (monster hunting) relaxing, as a result, he traveled a hundred years forward by contacting a Time Turner—
Although not allowing certain beasts to taste a Magic Core Egg, William was somewhat unwilling...
However, come what may, since there was no longer the opportunity to bombard a certain island in the Pacific Ocean, William had no ideas left to continue making big plans, after a few years of life, that sense of separation brought by time travel has mostly dissipated, at least, the people around him now are alive—
Not only existent in text or film.
"So, I shouldn't have anything to worry about?"
Though Harry's face was still green, that look of difficulty had faded mostly, and his tone carried some unmistakable delight.
Even the flame on his forehead visibly danced.
"Of course, but there is something—this term, no wait, until Sirius is brought back to Azkaban, you'll probably be prohibited from leaving the castle, but..."
William's first half of the sentence made Harry's expression shift from delight to loss, then increasingly bitter, but the final twist undoubtedly once again captured the boy's attention, even Ron and Ginny next to him instinctively listened closely to William's next words—
"...there's good news."
"What is it?"
"You definitely won't be idle bored this year, Cedric's spoon-feeding education is about done, next it'll be your turn, I'll help you with the schedule."
"?"
This TM is good news?
Looking at William's smirk, Harry could only reluctantly tug the corner of his mouth, unsure what expression he should have, he purposely didn't seem too disappointed, but forced a smile and nodded.
"Isn't this good? This is a one-on-one class with a Duel Master—"
Seeing William head toward the Hufflepuff long table, Ron slid over again, feigning surprise, "Rumor has it many in the school beg for it."
Harry showed no emotion, just gave Ron a sidelong glance, meaning clear—if you want it, I'll trade you.
That's still better—between freedom and studying, hardly needing any thought for Ron to pick, besides, those rumored beggars, are all members of the William Richard fan club—come on, if not for idol chasing, who really thinks of adding to their workload?
Oh, not including Hermione.
She's ferociously unlike a human, and the books in her backpack nearly taller than her, Ron and Harry still can't figure how she managed flipping time zones.
Under William's influence, a tasteless lunch passed hastily, Harry didn't even know how he left the castle to the Forbidden Forest edge, till Hermione suddenly popped beside him, he finally snapped back—
Ron and Hermione had stopped talking with each other.
Thus, Harry chose silently tagging along, yesterday's torrential rain now unseen, the sky now was a clean, refreshing light gray, beneath their feet the grass was damp and springy.
The group moved down the grassy slope toward Hagrid's cabin at the Forbidden Forest edge.
When Harry spotted those three very familiar backs at the front of the line, did he realize they seemed to be sharing the class with Slytherin students, Malfoy was animatedly talking to Crabbe and Goyle, making them laugh coarsely, Harry could basically guess what they were discussing.
Probably his forehead flame.
"Come, come, gather 'round me now—"
Hagrid's rough voice resonated around the Forbidden Forest edge, clad in his moleskin coat, his large hound Fang beside him drooping its tongue out for cooling.
The chaotic chatter abruptly vanished, Harry felt a clarity around his ears—on Hagrid's face was excitement, he seemed to think it was his authority, but Harry could tell it was because of the figure standing next to him.
William, what is he doing here?
This was almost every third-year little wizard's puzzle, this transfer student's fame after nearly a year's fermentation had almost reached parity with most professors—though ultimately still a student, or perhaps... assistant teacher?
William hadn't never been an assistant teacher, quite the opposite, besides his Duel Club duties, he helped Professor Sprout care for the greenhouse, on the occasion teaching some grades, while saving a few little wizards from Devil's Snares.
"All right, um, follow me everyone—"
Hagrid led them along the Forbidden Forest edge walking, five minutes later, they found themselves outside a small enclosed yard, nothing inside beyond.
"Now, open your textbooks—"
