Newt Scamander had been watching the goings on from the steps of the auditorium. He saw Grindelwald summon a flaming kitten from a wall of fire. He heard Albus Dumbledore laughing and watched him rolling down the steps. And suddenly it occurred to him that there might be an easier way to subdue the dark wizard.
He moved towards the ring of fire, one hand reaching into his coat pocket as he descended the stone steps. His fingers closed around a cylindrical object, and suddenly he heard Grindelwald speak.
"Mr. Scamander, do you think Dumbledore will mourn for you?"
This was it. Grindelwald had raised his wand and was about to curse him into oblivion. If he didn't act now, he might not get a second chance.
Newt whipped out a feathered cat toy, the same one he used to catch the Zouwu from the circus.
Grindelwald froze, the half spoken incantation dying in his throat. He stared at the toy, seemingly mesmerized by its dangling feathers and jingling bells. "Mine?" he squeaked, his voice sounding ridiculously high. He pointed to himself, a faint but hopeful smile curling his lips. "Is that for me?"
"Come on now." Newt wiggled the toy, causing its bells to sing in unison. "Come on." He then began to move towards the entrance, thinking that maybe he could distract him long enough for his friends to escape.
The dark wizard got down on all fours, the Obscurial forgotten as he chased after Newt. But Credence wasn't having any of it. He had come here for a reason, and he wasn't going to let this man stand in the way of getting the answers he so desperately needed.
Swallowing his fear, the Obscurial came forward, grasping the dark wizard by the sleeve of his coat and pulling him towards the center of the auditorium. "Please, sir," Credence murmured, his voice no more than a frightened whisper. "Please, I need to know who I am..." His voice trailed off into silence when Grindelwald spun around, glaring at him out of his black and silver eyes.
Credence bowed his head, too terrified to run and too afraid of letting go. Those horribly mismatched eyes traveled downwards, slowly, and for a moment Credence felt his heart stall in his chest.
"Please," he said again, desperation shining in his eyes.
Grindelwald's gaze lingered on the boy's hand, on the scars that laced his fingers, and suddenly he remembered.
"That's right." That familiar grin cut across Grindelwald's pale features, his eyes alight with malicious intent. "You're coming with me." He took one last look at the colorful cat toy then vanished, returning to Nurmengard where he would have all the cat toys, yarn balls and scratching posts his heart desired.
