Ivory-x-Ebony, you do have a point. In my fanfiction, Dante and Vergil, had Megara removed from the forbidden text in order to protect her, after their parents died. Therefore the Order of the Sword does not know that Megara exists. But my point is that, Dante doesn't seem to have known Nero, before. So how could they be brothers, without their knowledge of each other. One would think that Dante, would have remembered his mother being pregnant. So if Nero is Sparda's son, maybe Eva, isn't his mother...
To GamblingGambitCloud: the old woman in Dmc 2 is named Maytr and I really doubt Mundus could possilably feel pity for anyone, descended from Sparda.
