Upon hearing Harry's words, Cassandra's face showed extreme disgust.
"Don't let me find out where he is," she said through gritted teeth, "because if I do, I'll make him taste the lightning..."
This really is a dark past, no wonder Draco hesitated to speak several times. It turns out it was because of this...
"Besides this diary, I think there's also a ring that could possibly be a Horcrux of Voldemort," Dumbledore said once more. "I saw this ring in Moffin Gaunt's memories. Additionally... the ring mysteriously disappeared, and as we had previously speculated, it very likely was stored with the portrait of Omnius Gaunt in the Lestrange family vault."
At this point, Vivi took out a lock of hair from beside her.
"This is Bellatrix Lestrange's hair. The owner of this lock is Voldemort's most loyal follower—perhaps we can use Polyjuice Potion to transform into her and go into the Gringotts vault to investigate."
"But Bellatrix Lestrange is a high-security prisoner in Azkaban," Newt said with furrowed brows, "I don't think Gringotts will assist us to access the vault on her behalf."
"Oh, that is indeed the case," Dumbledore mysteriously smiled at Harry. "Actually, we can completely force the fairies to allow us access to the Lestrange family's vault through certain channels – but that would undoubtedly harm Gringotts' credibility."
"But if we use this method, it will alleviate the fairies' concerns. Even if someone finds out about this matter, we can brush it off with the excuse that 'it was Bellatrix Lestrange herself retrieving her treasure' after all, nobody would think someone could really obtain Mrs. Lestrange's hair and magic wand to impersonate her in the vault."
"Quite a good plan," Harry understood Dumbledore's intention, which also offered the fairies an excuse and a way out.
Disguising as Bellatrix herself isn't important; what's important is that it will be an excuse of convenience for Gringotts.
"Thus," Professor Dumbledore looked at Vivi, "this will require your effort, Senior Grindelwald—I happen to know, after spending over a decade in Azkaban, Mrs. Lestrange's mental state... isn't very stable."
Well, to put it bluntly, she's a lunatic.
Vivi suddenly lifted her head, bursting into maniacal laughter.
Her hair suddenly fell to cover one eye, while the uncovered eye scanned everyone in the Headmaster's Office. Her white teeth bit her red lips pale, with a hint of a crazy smile.
"Potter." She walked beside Harry, her knee resting on his leg, reaching out to grab Harry's collar, "Is this the feeling, Potter?"
"If you tone it down a bit, it'd be more like her," Harry quickly said, feeling pressured by Vivi's mental state.
Everyone nodded, and Cassandra squinted her eyes, muttering softly, "That crazy woman from the Grindelwald family."
To be fair, Vivi's mental state just now was indeed a bit insane, making it hard for Harry not to ponder if he chose Cassandra over Vivi, would she become like this.
Of course, the conclusion is a ninety-nine point ninety-nine percent chance that she'd become such a lunatic yandere, because she has turned like this before—just like that time she pulled Harry's collar, demanding him to cast the Drilling Curse on her.
"I happen to know Severus has some Polyjuice Potion," Dumbledore said again, "If you have time, perhaps you could try your luck at Gringotts..."
"Us?" Vivi asked.
"Yes, you," Dumbledore once more gave Harry a mysterious smile, "I know Harry has some pull at Gringotts, if he goes with you, it might save a lot of talking."
Vivi immediately understood Dumbledore's intention and looked approvingly at the sensible junior student.
You think Dumbledore is doing this on purpose? Well, he is a bit.
As a backbone of the Harvey Party, he is quite willing to match the two—highly willing.
Of course, when saying Harry holds sway at Gringotts, Vivi's influence isn't light either. After all, as the malevolent duo of their time, she also has left a formidable reputation among the fairies.
Nonetheless, Vivi didn't wish to dismantle Dumbledore's words, nor did she refuse a business trip with Harry.
Dumbledore winked at Harry, summoning Fox to fly over, whispering a few words to it before Fox vanished on the spot.
Soon, Snape appeared in the Headmaster's Office, holding a large barrel of Polyjuice Potion with an expressionless face.
"Dumbledore."
Snape placed the barrel of Polyjuice Potion on the table, the potion splashed a few ripples, making splashing sounds.
"Here's the Polyjuice Potion you wanted—I hope next time you want me to brew a potion, do notify me ahead of time, so I'm better prepared."
"Thank you, Severus," Dumbledore seemingly ignored the sarcasm in Snape's words, speaking calmly.
Vivi stepped forward, dropping the hair she held into the Polyjuice Potion.
The hair fell into the Polyjuice Potion, which bubbled thickly, swallowing the lock completely.
