Sephiroth shrugs slightly. "If that is the case, then you hardly need concern yourself with me or anything I say, correct? You don't have to understand or trust anything I say if you'll soon put this situation behind you."

In truth...Sephiroth is tired. Guilty and exhausted and frustrated that even his best faith efforts are being met with this stonewalling, even if he can hardly blame Cloud for his mistrust. But if it's impossible for anything of value to be accomplished here, then he'd like to be able to leave...and that means convincing Cloud to disengage. He'd like not to turn his back and have Cloud shove the Buster Sword through his spine, again.
