"You have consistently disappointed me. It has always been the humans over family," Sephiroth replied dispassionately, his gaze never leaving whatever it was he saw outside the pane of glass. "It has always been them over us for you."

Sephiroth folded his arms over his chest loosely, still not facing the other or letting his face be seen past the shade of his hair.

"Time passes no faster in the Lifestream than it does on Gaia. It is slower if anything, all things happening at once and a single event going on for eternity. I have watched these long years, waited patiently as it all passed, and I grew angry. I wanted to punish you for betraying me for them."

He was silent then, taking a breath and releasing it slowly.

"I had to even consider if I were human enough to fall prey to their pettiness."

Sephiroth shook his head slightly, a tinge of regretfulness in his voice.

"In the end, I decided that I was not. You were merely imperfect, flawed in a way I could not correct. Infected as the case was."
