my momentum is tumbling me towards the edge and i 'm turning to try and catch myself and i can see her lifting the knife and i can see her stepping forward and i 'm falling into the ledge and my fingers are slipping on wet stone and i can see aaron sitting up and he 's only got one eye now and it 's staring at viola as she 's raising the knife and she 's bringing it forward and i ca n't stop her and aaron is trying to rise and viola 's moving towards him and i 'm hitting the ledge with my shoulder and stopping just short of falling over and i 'm watching and what 's left of aaron 's noise is radiating anger and fear and it 's saying no- it 's saying not you- and viola 's raising her arm- raising the knife- and bringing it down- and down- and down- and plunging it straight into the side of aaron 's neck- so hard the point comes out the other side- and there 's a crunch , a crunch i remember- aaron falls over from the force of it- and viola lets go of the knife- she steps back .
