"They don't exist in your world either?" Thanatos asks softly. One doesn't exist. He doesn't have a counterpart, does he? But then why does he have this feeling? Why does he wants to reach out to all of this, embrace it, and never let it go? Now that he knows that absence is there, Thanatos doesn't think he could convince himself it's not there or move on.

Blood and darkness, this is similar to what a mortal feels when Thanatos takes a single loved-one but not the other, isn't it? But at least they knew what's missing in their life.

Thanatos sighs and lets his head hang. "We're not going to find answers here either way, but I... I don't know. It's a lot."
