Spolier : After the Jury Consultant falls off the building under construction, McGarrett grabs his right hand and stops his fall. McGarrett then tells the consultant to give him his left hand so he can pull him up. When the camera angle is looking down, the consultants left hand is down at his waist. When the camera angle changes to looking up, the consultants hand is grabbing the edge of the concrete slab. Then the angle changes to looking down again, and his arm is back at his side.
When trying to pull Sutherland back up, Steve grabs hold of the scaffolding, but when the shot changes, his hand is back in the floor.
When Steve finds Joe's phone on the floor, it still says 'incoming call McGarrett'. Steve is no longer calling the phone, and so that shouldn't be on the screen.
