Possible Spoilers. [Nero's arm was infected by Virgils departed spirit, that's why he has a direct bloodline to Sparda. Could Dante really be Uncle Dante? Could he have been Virgil's son? The Yamato reacted with him, but no one else. watch the cut-scene right after you fight Dante the second time you see the cliche "son is walking off after Ive taught him a good lesson, I'm so proud of him" thing. he even says I gotta keep it in the family. He could be a descendant of Sparda or the son of Virgil or Dante. I'm just tryin to make a connection as to why Nero is so much like Dante and Virgil. We know he was an orphan, but why? Do you think Dante could've looked after him while he was doin his crazy devil hunting? Do you think because Virgil died he became an orphan? Dante said the Yamato had to stay in the family, and let Nero keep it at the end. Sanctus said he needed a direct blood relative of Sparda to make the Savior become powerful? So could it be that Nero is one of their sons?] Just thinking in typing format.
