i was watchin the dmc 4 cutscenes, and i just realized something about nero....he must be related to sparda because he'sso strong that in the first fight with dante, he punched him so hard that he forced dante to quickly shift into his dt against his will....that said, we haven't seen that kind of reaction since vergil first awakened him....so...i'm definitely saying that nero has some blood of a demon in him and it is, indeed, not an infection or demonic posession with the db
