Mundus reference
Complete the game and get the Vergil ending, where he falls down in the pool of blood. There will be three round and red electric orbs that he says he could defeat if his father did it. This is most likely Mundus, the last Boss from the first game, because Vergil obviously loses and succumbs to Mundus' power.
