[ Shiro can hide his fear all he wants, but Lelouch knows better. He can smell it on him. That's what wolves did; they followed the scent of blood to its source, surrounded their prey when it was at its weakest, and with claws and fangs extended... subsequently tore it to shreds and devoured it bit by gory bit.

And that's exactly what Lelouch intends to do here, because a quick, painless end is too kind, and Lelouch is too cruel to stifle the ever present urge to play with his food until it can no longer fight back, drained of strength and entirely absent of will. ]

Why would I do something so foolish? Why would I waste a life that holds so much promise, so much value?

[ Lelouch stops a few inches away, reaches up to the bottom of his mask, tugs at it sharply. ]

But while you're right regarding my identity, there is a detail you touched upon earlier that is far more pressing, far more important...

[ A mass of brown hair falls away from the mask, a delicate face revealed that bears a demonic curse glowing in its left socket, the unmistakable mark of Geass. ]

...and that is that I am the most repulsive monster you will ever met.
