Allison uses a stun bomb to knock Alex unconscious during a fight in a power plant. Stun bombs are smaller and less powerful than grenades, though they often leave a target burned from the small explosion of fire they produce.
A small object flew through the air toward him. Ash didn’t have time to scream at him to get away before the stun bomb exploded right at his feet. The explosive detonated in a burst of fire and smoke. Ash saw Alex’s body fly backward, and he collapsed in a heap several yards away against a metal power generator. His clothes were blackened and smoldering. He didn’t move.
