[Nero looks a little lost for words before Vergil answers, both unsure of what to say and honestly a little unsure how it is possible. It falls under the umbrella of "demon bullshit," the catch-all where Nero has organized many of the confusing, inexplicable things about himself and his own body. Without any clues to go on, and lacking any guidance from someone else like him (Dante hadn't been exactly forthright all these years, and Nero was often too embarrassed to ask him) a lot of it simply had to be shrugged off or accepted without a good explanation.

But Vergil does explain, and Nero looks about as glued to the answer as Kyrie is. Then he nods, adding his own thoughts so as not to look like he's completely out of his depth when it comes to his own... well. Demon bullshit.]

Yeah, basically I got my powers back. And a bunch of new ones too. [Here, he summons one of those glowing blue wings on his shoulder, gesturing to it with a thumb.] The arm was just kind of a bonus, but... it's really great to have it back.

[A beat.] Even if it looks weird and human now. [Boy, is that a shift from what he used to think...]
