Thanatos asked, "Heaven Slayer told you to do this?"
Black Zetsu replied, "According to Lord Heaven Slayer's instructions, I don't need to go out of my way to do anything. I only need to keep events moving and wait for the right moment.

Black Zetsu asked in confusion, "Follow the original plan?"
Thanatos nodded. "Yes,
