Maybe because I never said they were exactly the same. Only that what truly defines the character and what makes Vergil Vergil is there. Same with Dante.I'm confused. You're the one that has said the two aren't that different at all, that Vergil is Vergil at his core. If that is indeed true, I see no reason why this one specific thing would be the degree of separation.
And again, there's no theorization to be done. Nero being Vergil's son is fact, plain and simple. For that to be the case (Which it is), and Nero to about in his late teens in DMC4 (Which he appears to be) Dante should be in his mid to late thirties by the time that game takes place. Something of that nature, anyhow.
And I won't believe Vergil is a daddy until I get concrete proof, and even then it wouldn't change how stupid it is.
