What would happen if I made you the Sinner of destruction and I was the Sinner of Thunder?
If i was the dark hair sinner of thunder then I would simply leave you there to sacrifice yourself without any help at all. I was created to guide you, I am tired of trying to stop you from running away each other. This is a lot more fun to me anyways.
Just place us in character roles and see what would happen.
Khaleesi claims she loves the Raiden Shogun. The writers ask her: "Oh really?"
Become the one who can fight for an eternality then. You who was forced to take that role as you solely watched all of your friends and everyone you loved disappear right in front of your eyes.
In true you are the Makoto who disappeared and I am the one who can fight for an eternality. It should be obvious by now.
