He's only half-listening to what Vergil says as he makes a mental list of his interests. Reading... good, that one's obvious. Baked goods? Wonder what he's sampled that tastes so good. Cats? Does he like them or not? Why stay there to eat if he doesn't at least tolerate their company? Aww...

Nero zones back in at the mention of sparring. With a... friend? Vergil has friends? Wow, good for him. A friendship based on sparring is pretty predictable. It's the ruleset that makes Nero raise an eyebrow.

"That should go without saying." Maybe his friend's a glutton for punishment. (After all... he's friends with Vergil, isn't he?) "People duel to the death around here often?" And yet the Sparda twins have managed to refrain? Now he's really proud of them.

"There a lot of other people like... well. Like us around?" Nero gestures vaguely. "Demons and shit?"
