About the art book, I haven't seen it personally, nor can I read Japanese, so I can't say. I actually read it on these forums. It was mentioned in the other Nero origin theory thread (btw why are there two? I'm confused.)
http://devilmaycry.org/threads/just...at-silly-nero-being-vergils-son-theory.16865/ You'd have to ask them. I don't think they'd have any reason to lie about it.
Ten years after DMC3. In DMC3, Dante is 19, so he must be about thirty in DMC4. If Kobayashi or whoever it was said that he's ''around ten years older'', then I believe him. If Dante were around forty, he would've said ''around twenty years older than in DMC3''... and there's a big difference between ten and twenty. Even if he himself doesn't know how old Dante is, he would not make such a huge mistake. And to me, Dante does look like he's thirty. If you still find it hard to believe, I'd suggest looking at Lady. She was also about 19 in DMC3, and she looks like she's thirty in DMC4. If she were forty, I'd expect her to be less... perky. :laugh:
I really, really wish someone could find that interview and post a link. I've looked for it myself but found nothing but dead ends. Frustrating because I've actually tried to build a timeline for DMC in the past but couldn't find ANY sources. (Besides in-game ones obviously.)
True, I had forgotten to consider Lady's age into the equation. But there is a very simple explanation for her perkiness. Implants! XD
I see a lot of people using Dante's "it's got to stay in the family" line as evidence that Nero is Vergil's kid. But here's the thing, Dante says that when trying to get Nero to give the sword to him. Dante used the sword needing to "stay in the family" as a reason for why Nero needs to give Dante the sword. What Dante basically said, is that the sword needs to stay with him, as the last living member of his family. Subtext.
At the end of the game, when Dante lets Nero keep the sword, he never once says anything that can be interpreted as Nero being family. Dante says the "it's got to stay in the family" line in a completely different scene and context. His decision to let Nero keep Yamato has nothing to do with Nero being family. Dante let's Nero keep the sword because he knows he can trust Nero with it.
Just saying.
Sadly, that one quote is not the only evidence presented in the game.
1. He says "It's gotta stay in the family" and ultimately ends up allowing Nero to keep the sword, indicating he at least suspects he is blood related. I'm looking at the bigger picture, not just the subtext of that one scene.
If he didn't think he was family, you really think he'd allow him to keep his brother's sword in the end? >.> I'm not so sure.
2. Nero is able to "heal" the broken Yamato. Would Dante have been able to do the same thing? Maybe. Who knows? But the fact is Yamato chose to react to Nero, and no one else, for some reason or another.
3. "GIMME MOAR POWA" Need I say more? XD It's almost a direct quote from Vergil. Sure I guess it *could* mean anything. But this is DMC we're talking about, not exactly known for it's deep storytelling.
4. Nelo/Nero mistranslation issues. Despite what was said in Deadly Fortune, I highly doubt his name being "Nero" has much to do with some emperor. =/ It's just toooooo much of a coincidence.
All these things put together, don't you think the theory holds at least a little bit of weight? All circumstantial evidence? Perhaps. But I'm pretty sure if he was on trail he'd be found guilty. Sucks too, they pulled the same crap with Wesker, come to think of it.
Sometimes I think the only way to convince people is to pull a RE6 by making it extremely obvious and just call him Vergil Jr. XD Lol.
But like I said, this is just my opinion, and I still don't really LIKE the idea of him being Vergil's son.
I'm not trying to change your minds or anything. Capcom seems to think it's all right there on the surface. Maybe it IS all right there on the surface, but because Nero's not really a popular character, we don't want to see it.
