Sephiroth doesn't answer, he just smoothly shook his head, carefully searching Ib's eyes as if he might be able to somehow communicate the fact that it didn't matter if they were here or not. The foundation of who he is, much like anyone, is based on how he was raised and if the values they instilled in him...the pride that he thought he developed for himself...if it is all a lie then who exactly does that make him?

"It doesn't matter if they aren't, they helped to make me who I am as a person. The fighter that I am. The Hero that I'm supposed to be here."
