When Aggie saw that the witch's target was the crazy customer, she breathed out in relief. Help, not hindrance, then. The freezing spell stopped the thing in its tracks, though there was a slight trembling as it tried to break out of it. Thankfully, it gave Aggie enough time to get within range and cast her trifecta.
Binding spell, wrapping ropes around the body. Transfiguration of the ropes into steel bonds. Relaxing spell to keep it from struggling but keep the heart beating. Now she could breathe. She stepped over to the body and took out a paperclip from her pocket. She clipped it onto a lapel, next to a small pin, and stepped back as she spoke a quick spell.
The body disappeared as it was portkeyed out.
She leaned against the nearest wall, exhausted. Her last pepper-up potion was nearly out of her system and she was beginning to feel the last 26 hours down to her bones.
