Nero shrugged casually, leaning back on his seat, devil arm slowly slipping into sight but not exactly enough for someone to actually realize it was a devil arm - it could just look like a fancy glove or armband to anyone.
"I was just curious," Nero said nonchalantly, though his sharp eyes caught on Vergil's hand putting the drink down. If he does confront you, try to avoid physical combat. It'd really suck to end up losing either of you again. Dante's words were still vivid in his mind and he decided to try and placate things for a bit. Which was actually rare for Nero, since he didn't give a rat's ass if he started a fight or not.
But the thing was, he was actually doing it for Dante more than himself. If it came down to him, he'd want to know if this guy was just as good as Dante or not. "I've been here for a while and now you happen to be the one whose name I haven't caught yet. No need to get your knickers in a twist."
