Vergil's of course has his name carved in the back. The moment you see that, his face also comes back to you, and something in the distance rumbles.

And you won't be able to return Dante's to him, because as soon as they're near one another, they seem to be magnetically pulled toward each other, and form a single pendant. When you look back at Dante's body...it's gone. Along with all the blood, any evidence there was a murder here.
