Kat cursed under her breath as she heard the offer.  The sounds of death and agony rang in her ears.  She wanted to leap from her hiding place, even if it was to save just one.  But she also knew there were no assurances that those butchers wouldn't slaughter the rest when everyone revealed themselves, or just leave them to die.  There was no way she was going to just TRUST anyone in the Imperium.  So she stayed crouched and hidden, her heart about ready to pound out of her chest.
