As Newt and Percival fought down below over Credence, Madam Picquery finally arrives to the scene surveying the situation from under the magical force field with a calm and collected notion as (Y/n) tries to explain the situation that they're in while a crowd of policemen and No-Majs swarmed the subway with their cries and chattering becoming louder and louder. Reporters photographing the scene with increased frenzy. "Please, Madam Picquery—there's no need for all this. This isn't like any Obscurial that has been dealt with in the past and we should take extreme caution. All of this will only make things worse—!"

     "That thing killed my son—I want justice!" Shaw Sr. had shouted, cutting (Y/n) off as her superior looked out at the crowds, "I'll expose you for who you are and what you've done."

     "You still think there's no need for all of this, (L/n)?" Madam Picquery inquired calmly as (Y/n) bites her cheek worriedly.

     "There's something you need to know, Madam." She stated shakily, clenching her hand in her pocket around her engagement ring, "There's been someone among us whose been behind all this chaos." She said as Madam Picquery looked down at the young woman with a look of concern and intrigue. Before (Y/n) could say who, the entrance to the subway bursts with a strong dark energy as the Obscurus crashes up through the pavement. Making everyone's attention quickly turn to the source as it stormed up a half-built skyscraper, windows shattering at every level, electric wiring exploding until it reached to the very top of the framework of scaffolding above, taking a sudden pause. (Y/n)'s eyes widen as she quickly catches on to the situation at hand and shouted for both wizards and No-Maj alike to hear, "EVERYONE TAKE COVER NOW!" She ordered as everyone inside and outside the magical cordon run for cover while the Obscurus forms a wide disc shape before plunging at quick speed back down into the subway, leaving a ginormous hole into the pavement.

     Everyone can hear the Obscurus scream and tear through the underground subway as it echoed out everywhere. (Y/n) looks up at Madam Picquery as she stands up straight, seeing how much of a threat the force was she ordered in a calm but authoritative manner, "Kill the Obscurus, at whatever cost." She said as Aurors nod and start to file into the subway, going after the Obscurus. (Y/n) tries to protest.

     "But Madam—!" She exclaimed before her superior looked at her sternly.

     "We don't have much of a choice, (L/n). Now get down there and kill the thing." She ordered as (Y/n) clenched her fists.

     "Percival is behind all of this!" She exclaimed as Madam Picquery paused and looked at (Y/n).

     "Graves is behind all this? Your fiancé? Impossible." (Y/n) took a deep and shaky breath as she nods.

     "Yes, he is. I didn't want to believe it at first, but after recent events I came to the conclusion that he's been behind all this chaos. He's been so different and distant since the mission to Europe and I want to get to the bottom of this." She said as Madam Picquery stared at her and placed a hand on the young woman's shoulder in a reassuring manner.

     "We'll get to the bottom of this, I assure you." She said, "But first we need to take care of the situation at hand." (Y/n) bites her inner cheek and nods before they both hear the sounds of screaming and howling are heard from the deepest part of the subway is heard and the magical force field begins to break before a sound of explosion is heard and white light is seen from the outside. (Y/n) feels sudden dread and sadness at this as she stood there in shock, "We should get going and see if the job was taken care of." Madam Picquery informed as (Y/n) nodded and the two quickly head down.

     All power had been subsided as only small tatters of black matter are left—floating through the air like feathers. Newt gets to his feet with his face full of grief and Tina remains on the floor crying. Percival stumbles onto his feet and onto the platform, standing as close as possible to the remains of the black mass, Aurors advanced towards him.

     "You fools," Percival started in disbelief, "Do you realize what you've done?" Percival snapped at the others as they watched him closely. Madam Picquery and (Y/n) come in from behind the Aurors as they arrived to the scene.

     "The Obscurial was killed on my orders, Mr. Graves." She informed bluntly and in a questioning manner. Newt and Tina look at (Y/n) and she gave them a sad look that said that she tried everything she could to avoid Credence's death.

     "Yes. And history will surely note that, Madam President." Percival growled as he moved towards her in a threatening manner, "What was done here tonight was not right!" 

     "He was responsible for the death of a No-Maj. He risked exposure of our community. He has broken one of our most sacred laws—." Percival cuts her off with a bitter laugh.

     "A law that has us scuttling like rats in the gutter! A law that demands that demands that we conceal our true nature! A law that directs those under its dominion to cower in fear lest we risk discovery! I ask you, Madam President," He spat while looking at everyone else at present, "I ask all of you, who does this law protect? Us?" He gestures vaguely to the No-Majs above, "Or them?" He then smiles bitterly, "I refuse to bow down any longer." He said before walking away from the Aurors.

     "Percival—!" (Y/n) exclaimed, about to go after him before Madam Picquery holds a hand out in front of her to stop her.

     "Aurors, I'd like you to relieve Mr. Graves of his wand and escort him back to—..." She begins as Percival moves down the platform, a wall of white light suddenly appears in front of him, blocking him from his path. The Auror stands there and thinks for a moment, with a sneer of irritation, he suddenly turns and strides confidently back along the platform while firing spells at both groups of  Aurors facing him. Spells flew back at him from all angles but Percival parried all of them, sending several Aurors flying and he appeared to be winning. That is until in a split second, Newt pulls out a cocoon from his pocket and releases it at Percival, the Swooping Evil soared around him which shielded Newt and the Aurors from Percival's spells and gave Newt time to raise his wand. He slashed it through the air and a sparkling rope of supernatural light flies out and wraps itself around Percival like a whip. The Auror tried to fight it off but it only tightens and he starts to stagger and struggle before falling to his knees and dropping his wand.

     "Accio." Tina says as his wand flies into her hand, Percival glared at all of them with deep hatred in his eyes as she and Newt slowly advanced towards him with Newt raising his wand and pointing at Percival.

     "Revelio."
