[ Arden squeezes her hand back and is following along until she gets to that name. Perhaps out of respect for his situation, he really hasn't been told much of what happened after his death aside from the nature of Roxas' connection to Sora, how Ven fits into that picture, and how Riku ended up looking like Ansem for awhile but that he got out of it. Riku 1.0 might have mentioned DiZ in passing, but not in a way that Arden attached to significance. ]

You don't have to tell me more about him if he's part of what's been eating at you, unless you want me to know who he is so I can keep an eye out for him like Vanitas.
