Marluxia pursed his lips as he considered that question. "You'll scare him," he answered. That part was easy enough; Lumi felt powerful, and was to all appearances a staunch ally of Marluxia's. That was plenty to make Vexen wary of him, and Lumi's demeanour would do the rest.

In truth their relationship was more complex. They were allies, but not quite friends, and yet Marluxia had been able to trust Lumi with something as delicate as pushing him in training with Graceful Dahlia. It was partly convenience, partly necessity, and, lately, partly trust that kept them together.

But Marluxia liked to keep the outward perception that Lumi was his, rather than their partnership being one of tentative, possibly equals. It meant people underestimated Lumi's intelligence, if not his power, and considered Marluxia too dangerous to mess with.

"Neliel is unlikely to spook him; she's a kind hearted woman with a will of iron, and her elemental affinity goes in her favour. Zexion's little friend, however," Marluxia frowned, trailing off while he considered how to explain it.

"Darkness clings to that one, even when he isn't fighting. He'll either intrigue Vexen, or frighten him. Possibly both."
