Look, games are one of his first languages; especially cards and numbers. Of course he'd get them. Even if it's different, he did watch a few of the others once or twice playing video games at the Tower. But because it's been so long, he defaulted right back to cards.

"Depends on who you ask," he answers honestly, before leaning against the wall by the door. "In Castle Oblivion, it didn't matter. All save three used it in some way and they clung to the light so tight they lost their way." Partly because he inadvertently lured them further in; he winces slightly. "Most other worlds fear the dark and bathe in the light, but it isn't the power that's inherently evil... it's who wields it. Riku's proof of that. He uses it to protect others. I only knew how to destroy."

He can't form a shield like he can; can't use curative spells back home, either. Sure, someone once taught him more magic, but... it was all an illusion and theories.
