Spoiler!! McKeen then comes back towards the car. Warrick's eyes go wide and he tries to say something to Grissom, but he has no voice (Presumably his vocal chords have been severed by the gunshot wound to his neck) When Grissom bends down to hear better and says “What” McKeen puts his hand on his sidearm, apparently ready to shoot both Grissom and Warrick, However Warrick can only choke up blood, and he starts fading. Grissom looks up at McKeen (though not as shown in the first promotional pictures to be leaked) and demands “Where are the paramedics” McKeen walks off and calls them, and we hear sirens in the background. Grissom pleads with Warrick to hold on, to fight “Fight for me Warrick” he says. Grissom is trying to hold the throat wound closed with his hands. Warrick dies in Grissom's arms, and Grissom quietly says “No”, he then lifts Warrick's head and shoulders into his arms and holds the dead man to his chest.
