His outburst seemed to finally get to her. She shut up and stopped drawing the attention of who must not be named.
She even left him, which gave him the peace and quiet needed to contemplate his recently acquired sense of mortality.
It is not something he is used to the Cosmos. He had always been carefree and unfettered. He thought he would live forever.
Not even ANNIHILATION attacking the Cosmos changed that belief. But ever since the Supreme died, he has realized that death is a real possibility for him.
He didn't want to think about it, but eventually his thoughts returned to her question. He too wonders many times how the Lord of Madness managed to subdue ANNIHILATION.
He knows how the Lord of Madness became the Supreme. Well, not exactly. He only knows what requirement the Lord of Madness met but not how he achieved that requirement.
In the Cosmos, if one is to become a Supreme, one must possess 51% of the total power in the Cosmos.
