As she is about to stop in her tracks, she takes her position on the spot as Estella prepares; she makes a throwing pose as she lets go of the flame in her hand.
When she released it, the fire began to shape itself like a ball; instead of throwing it in the air, she slid it like a balling ball.
This made Edward surprised and confused for a second when the ball hit the ground. She then snapping on her hand, making noise through the hallway.
When the ball hit and rolled the floor, it then became flatted as if the floor was burning, as it began to move like a snake in the wild.
Estella then swiped her hands, as well as the flame, and turned left, blocking the hallway, making the imposter trap in their grasp. The fake Imposter turned around, facing the two with the classified files in his hands.
Estella took this time to throw another ball of flame at the man acting like Edward.
