Shinzon nods and moves closer to Ruekana, his breath hitting her neck as his mouth hovers there for a bit.  He then bares his fangs and quickly but as gently as he can he bites her neck and starts to feed from her.  He tries to make it as pleasurable for her as he can since she will be also turned by this.  So as he feeds he also injects his own blood into her so that she transforms into a pure vampire like him since at least in his family when they turn someone they are just as pure as they are.
