She made him chuckle a bit. "Oh, but you missed the obvious~" He chimed in, carelessly leaving the lifeless body where it was and going back to her. "You don't have to be silent for it to work. Just grab and go. Doesn't matter the angle, so long as you put some force into it. Come, come." And he went back those few steps to the body again, leaning down to hoist it up into a standing posistion, treating the dead man like a dummy. "Ignore the fact that I have more physical strength. This is something even you can do in your current state." He pushed the head back, forward and to each side. "No matter the break, it kills. If you don't think you have enough force by just your hands, bring your leg up as you yank down and have it meet the neck. Like so." And he gave a slow-motion demonstration for her. As the body came down, the side of body's neck cracked again against his leg.
He then dropped the body again. "You'll get the hang of it, the more practice you have, yes. Vampires naturally get better just by aging. Just know not to back down even if the prey turns to face you, and you should be fine. You can always resort to your binding blood trick if the situation goes sour." He grinned a bit. "Care to try it? There are more people in that direction." He pointed in said direction as he spoke. "Or are you satisfied?"
