'Who is this Varger?' Sephiroth wondered aloud, addressing nobody in particular. Whoever's Controllers noticed, he supposed.
Why are you making me do this? he thought, aware that the only reason he was thinking it was because his Controller was making him do so. Even his awareness of it was Controlled.

And masochistic too, apparently, given that he was now making Sephiroth insult him.
Well, either masochistic or determined to make an interesting contribution to a story filled with interesting contributions.
