Carrying the captured Occamy, everyone returned to the familiar safety of Newt's magical case.
For some reason, the Demiguise seemed to have taken a strong liking to Jacob and kept clinging to him throughout the journey.
Inside the case, Newt was carefully grinding herbs alongside Pickett, his faithful Bowtruckle companion.
"Hey, Newt, who is this girl?" Queenie asked, noticing a photograph tucked into his herb collection.
Newt stopped his work abruptly and fell into uncomfortable silence.
"Leta Lestrange. I've heard of that family. Are they..." Queenie began but was quickly interrupted.
"I told you, could you please not read my thoughts," Newt said, looking up with obvious distress.
"Sorry, when people are sad, their thoughts become much easier to read," Queenie said gently, approaching Newt with sympathy. "She's a taker, and you need a giver."
"Hmm, speaking of the Lestrange family, I'm actually classmates with their current heir," Aiden said casually, tossing a snack into his mouth.
"What are you talking about?" Tina asked, joining the conversation.
"School matters," the three British wizards replied in unison.
"You're discussing school. Does America also have a wizarding school?" Jacob asked, genuinely curious.
"Of course, Ilvermorny, the best magic school in the world," Queenie smiled proudly at Jacob.
"I think you'll find the best school in the world is Hogwarts," Newt said firmly, throwing the ground herbs into his mortar.
"Hogwash," Queenie replied, crossing her arms defiantly.
"Look, does Ilvermorny have anything like this?" Newt gestured toward the exceptional dragon-man student nearby.
"Don't mind them, everyone thinks their own country's magic school is the best," Aiden said diplomatically, patting Jacob's shoulder.
"What about you?" Jacob asked curiously.
"...Hogwarts."
While the group was chatting enthusiastically, thunder and lightning suddenly flashed across the sky, and Frank the Thunderbird changed color as he approached Newt with obvious agitation.
"Danger. Frank senses imminent danger," Newt said, staring at the bird with growing alarm.
Meanwhile, Grindelwald, still disguised as Graves, arrived at the orphanage where the Second Salem movement was housed.
"Credence, I need you to help me find that girl. She's very dangerous," 'Graves' said, touching Credence's head with false gentleness.
With a spatial flicker, following Credence's guidance, the two materialized in a run-down apartment.
"She's scared, so she came back here, wanting to find her brothers and sisters," Credence said, lowering his head submissively.
"Where is she now?" 'Graves' demanded.
"I don't know."
"You Squib, Credence. I knew it from the first moment I saw you," 'Graves' said cruelly, seeing that Credence was useless and finally showing his true nature.
"What do you mean?" Credence asked, sensing something terrible was wrong.
"You have wizard ancestry but lack the ability to control magic properly. Your mind is too inferior," 'Graves' said dismissively, walking deeper into the room.
"But you said you would teach me!" Credence choked out, his voice breaking.
"You are unteachable. Your mother is dead. That's your reward. We're even now," 'Graves' said coldly, turning to leave.
"Modesty, I came with your brother. Don't be afraid," 'Graves' said, attempting to approach the little girl hiding in the shadows.
But following her terrified gaze, he saw that all the walls behind him had collapsed, and standing there was Credence, transformed by rage and betrayal.
'Graves' finally understood that what he had been desperately pursuing had been in his hands from the beginning, but he had ruthlessly pushed it away.
"Credence, you can control it," 'Graves' said, trying to display the charm of his persuasive language.
"I trusted you completely, but now I don't want to control it anymore, Mr. Graves."
As Credence's words fell, the surrounding walls exploded outward, and a powerful dark magical force bloomed like a deadly flower.
Black particles mixed with red sparks, colliding and crushing everything that stood in their path.
On the streets and rooftops of New York, Aiden watched this approaching 'black fog' with fascinated interest.
"Jesus, this is what they call an Obscurial," Jacob said, remembering what he had heard during his brief imprisonment.
"He's more powerful than any Obscurial I've ever heard of," Newt said, his frown deepening with concern.
"I'll go first, see if I can reduce the damage to the city," Aiden announced.
Then he spread his arms and fell backward from the rooftop, transforming into a dragon that scattered silver-white particles as he chased after the destruction.
Black particles and silver-white particles collided violently in the air, canceling each other out in spectacular displays of opposing magic.
The two colors of magical energy entangled and spiraled, colliding again in the sky, then splitting apart and flying toward distant streets like warring comets.
"If I don't come back, please help me take care of my animals. Everything you need to know is written here," Newt said urgently, handing his case and a small notebook to Tina.
"Newt!" Following Tina's desperate cry, Newt disappeared in a flash of Apparition.
Tina hurriedly turned back, pressing the case and notebook into Queenie's hands. "You heard him, take good care of them."
Then Tina chased after Newt, Apparating into the chaos. Queenie also wanted to follow, but was held back by Jacob, and the two shared their fears through desperate mental connection.
In the distance, black particles were wantonly destroying everything around them, while the dragon formed by white particles clashed with the darkness several times, also having to protect the innocent pedestrians below, creating a dangerous stalemate.
With a spatial flicker, 'Graves' materialized nearby. "He's inside you, and you've managed to live this long. You're a miracle, Credence."
'Graves' drew his wand, wanting to capture and control Credence.
Newt and Tina also arrived at the scene.
"It's the boy from the Second Salem," Newt said to Tina with recognition.
"How did he survive so long?" Tina asked in amazement.
"Because his bloodline is incredibly powerful," white butterflies gathered and reformed into Aiden.
"Can we save him?" Tina asked desperately.
"We'll do our best," Aiden said, then flashed directly to 'Graves'. "Hello there, Mr. Grindelwald."
"You, Prewett. Wait, what kind of spell is this?"
Silver-white particles surrounded Grindelwald, forming magical chains. Aiden clenched his fist and delivered a powerful Stunning Spell.
After dealing with the false Graves, Aiden turned back. The black particles took the opportunity to break free from their restraints and flew toward the sky like an escaping nightmare.
Inside MACUSA headquarters, Picquery looked at the magic detection map glowing bright red. "We can't let the damage expand anymore. If it continues, we'll approach the exposure limit, and war with the No-Majs will follow."
With Picquery's urgent order, all available Aurors joined the desperate crusade.
On the rooftops of New York's Fifth Avenue, space kept flickering as new Aurors Apparated onto the battlefield. They immediately began using Blasting Curses, seemingly having reached the authorization for deadly force.
Newt deflected two Blasting Curses and shouted at the swirling black fog, "Credence, we're here to help you!"
Unfortunately, Newt received no response, and the destructive black fog continued moving at terrifying speed.
At the end of Fifth Avenue, the NYPD had received word and organized their personnel, using cars as cover while holding rifles to face the incoming supernatural threat.
The black fog roared as it devoured and crushed pedestrians and vehicles on the street. The police opened fire with everything they had.
But semi-automatic rifles were woefully insufficient against a rampaging Obscurial.
In the sky above, a silver-white dragon dove down, dispersing into particle form just before colliding with the police position.
These particles constructed white protective barriers around the officers, multiple hexagonal crystals forming a hemispherical dome covering the terrified humans.
The black fog collided with the crystal barriers, producing harsh scraping sounds like nails on glass.
The Aurors behind caught up, firing spell after spell at the black fog. Where the magic collided with the darkness, violent explosions occurred, and soon the black fog was forcibly dispersed by the combined assault.
