Time. Its effects and wonders never ceased to interest him with its flow and steadiness. There was nothing more constant and timeless than time itself and, despite the others' incredulousness at his "affection" for it, no one else ever tried to understand it in the first place. They could never understand why time was such a glorious thing - why, if he indeed had a heart, time would quite possibly be the first thing he'd love.
However, if there was one thing Luxord hated more than anything else, it would have to be (ironically enough) time travel. It ruined the natural order of things and, in essence, was a giant "fuck you" to his element. He made no effort to tell any other Organization member, not even the Superior, that he was capable of this ability. He made no plans to use it, not even if his life was at stake. Time was too precious to him, and he knew he would rather die than destroy its order.
This aside, there was no excuse for the bloody and mutilated corpse strung unceremoniously across the floor of Havoc's Divide. Without this important information, there had been no need to violently murder the blond man after he so clearly said, "Please, I need to warn you about something in the future!" There was no reason at all for Luxord's curt, yet irate, reply of "I despise time travel," nor tearing the man apart using a giant Ace of Spades.
After a good seventeen minutes of staring at his deceased self, Number X could only muster a weak "I have a feeling I am going to regret this later" before slowly departing into the portal of darkness.
