Fork!
He roared inside his mind.
I'm sorry, Fork!
Our good lad, Harry! He's been tricked by a Slytherin woman!
Not only does that woman look several years older than him, but she's also playing him like a fiddle!
He wailed bitterly at the sky, barking loudly, his two front legs furiously digging at the ground.
Fork! I'm really sorry!
No, I need to keep a close watch on Harry, absolutely not let him be fooled by a Slytherin woman!
How can our lovely little Harry have a Slytherin girlfriend!
Slytherins are inherently evil... bad guys, we must resolutely keep Harry from being led astray by them!
With this thought, Sirius made up his mind.
This time, in addition to catching that traitorous rat, I also have to stop Harry from being deceived by a bad Slytherin woman!
With this interruption from the black dog, Harry also felt like he should return to the Great Hall.
He still didn't know that the black dog is his godfather, Sirius Black.
Not far away, Cassandra was quite pleased.
This black dog is truly great, really sensible...
She walked briskly back to the Great Hall.
After Harry returned to the Great Hall, he went to Cassandra's side with Vivi.
"Cassandra," Harry said, "I have something to discuss with you—could you come with me for a moment?"
Cassandra raised her head, looked at Vivi, and smirked to the side.
"Oh, isn't this Potter with the bad woman?" She said standing up, "Does Mr. Potter have something to discuss with me?"
Despite her words, Cassandra's body was quite honest, following closely behind Harry to a vacant classroom on the second floor.
"Go on, what do you want to discuss?" Cassandra asked.
"I want to invite you to join my Dueling House, Cassandra," Harry said directly, "As you know, you're my good friend, and I want to invite you to join the Dueling House with us..."
"Ah, so that's it..." Cassandra leisurely said, "But I'm sorry, I refuse. I'm not interested in this childlike playhouse—Potter, have you forgotten something? You're a sixth-year student, not one of these idle kids, why are you always so caught up in playhouses?"
Harry wanted to refute, but before he could speak, Vivi chimed in.
"Just like our Dueling Wand, Cassandra," Vivi smiled gently, "We'll practice magic spells with each other, and have harmless duels—maybe I can understand this as your reluctance to face me in a duel? Facing me?"
Cassandra, with her prideful nature, was quite susceptible to provocation, especially from her romantic rival.
With Vivi's words, she immediately took the bait.
"So, you're also playing house with Potter." Cassandra waved her hand and said, "Then I'll reluctantly join the Dueling House—but I have one condition, Grindelwald."
"Harry is the head of the Dueling House, not me, Cassandra," Vivi said with a smile.
"Alright, my condition is that I want to duel with you in the Dueling House," Cassandra said with her head held high, "It's been years since our last duel practice, hasn't it, Grindelwald? Let's see if you've made any progress since you arrived here half a year ahead of me in this century!"
"Sure," Vivi smiled gently and said, "Rest assured, Cassandra, I'll hold back my strength to avoid making someone cry..."
The two of them faced each other unyieldingly, locked eyes, neither willing to back down.
Just then, a rumble of thunder sounded outside, and heavy rain began to pour.
"Alright, you two, please stop it now." Harry quickly stood between them, but his height was simply insufficient to block these two people.
Cassandra was nearly 1.8 meters tall, while Vivi... Vivi was already 1.8 meters.
Harry? He's just a little 1.6-meter bean sprout—boys generally develop height a bit later.
"See you tonight." Vivi said lightly, "Hope you won't cry, my dear Cassandra."
"Oh really?" Cassandra countered sarcastically, "If only your skills matched your words."
The two, eyeing each other, remained unyielding.
Then, they both simultaneously "hmphed" and looked elsewhere.
After dinner, around 7 o'clock, Harry quietly summoned everyone from the Dueling House and led them to the Room of Requirement.
Looking at the two extra big sisters in the team, no one knew what to say.
Hmm, they're all from Slytherin.
"Really miss this place..." Cassandra said after entering the Room of Requirement, seated herself in her familiar spot, "Just like before, right?"
"Alright," Harry sat in the main seat and said to them, "As you all can see, this time the Dueling House in the Room of Requirement will be expanded—We're welcoming two new friends, starting with Cassandra Malfoy, please raise your hand to welcome her joining the Dueling House."
Everyone raised their hands, especially Draco, raising his hands high.
"Didn't expect you to have French blood." Ron sarcastically commented.
Ordinary wizard families don't know about the joke about French surrender, Ron learned it from Hermione.
"My family does have French blood." Draco didn't catch Ron's sarcasm and answered boastfully.
