Leon could feel Ava wanted to escape hence she was trying her all to get away from him. Hence he misidentified as she was trying to run when she took a step back.
He sprung towards her to catch hold of her but before his hand could reach midway, Ava swung her leg with all the force and energy she could muster up by aiming his head below his jawline.
Her aim was the nerve next to his throat to give the pain that reaches his pressure point and keep hold of his breath.
Leon's eyes widened at her maneuver and he quickly reacted by pulling the carpet under her feet to lose her balance.
'Thud.'
The speed of Leon was a little late and his mistake was getting near her. Ava kicked him right at her target before her left foot lost balance and fell on the couch.
