Corvin strings his set between the building they’re on and the one across the way. Harry’s set snake their way around Pettigrew’s body, wrapping him up from knee to shoulder. His left arm is left free of the bindings at first. They levitate the unconscious man away from the building, until he hovers under Corvin’s prepared chains. With another cast, a second chain grows from the first; it reaches down and attaches itself to Pettigrew’s bindings. When Harry lets the levitation go, Pettigrew swings. Corvin hands him the broom; Harry mounts up. He swerves out to hover next to Pettigrew. He slices away the left sleeve of the man’s ruined clothing. With another short length of chain, he binds Pettigrew’s wrist to the links that holds him up, making sure the arm is nice and stretched out and the Dark Mark fully on display.
