We race each other to the car and dive inside headfirst, with Autumn beating me by a split second.

In that "split second", he must have realised Harry might be killed or injured, but Mr Justice Cavanagh said: "In the moment, you did not care if he lived or died."

The majority use one of two styles to achieve this, often in split seconds - pushing, or grappling.

A split second after “Action!” was called, I darted across the hall to a better spot and ran through the frame.

To be aware of, 'I'm on the ball here so this is what we trained' - but you have to think that in a split second.
