As he flew forward over the man he flipped and did a somersault in midair coming down facing him. Gemini threw a car at the man to block his view of him while he picked up a rock and used soul force on it launching it forward after the car. If the attack worked as planned then the car would hit the man with the rock ripping straight through it and striking afterwards. If not then if the rock touched the man at all Gemini would use his sutures to sew the man's right hand to the staff. He wouldn't notice it unless he had to try to leave it behind, but the amount of Ki it took was miniscule on Gemini.
