The Son of Sparda fighting the Son of Mundus actually sounds like a cool rivalry.WHAT ARE THE CHANCES IT REALLY DIED????
Think about it: that baby seemed like it can go around without Lilith. I know, I know, sounds far fetched. But what if, that baby manages to regenerate and self-sustain? What if Dante has to face it when he is older? Again, far fetched, yes...but couldn't that be possible?
