"Then make me understand-" But Price is gone before he can hear that Dan asks that sincerely, truly, earnestly wants to understand because he does care. He cares, and that reality is independent of any way Price can lash out at him. He isn't trying to be challenging; he's trying to offer help keeping the line of communication open.

But now Price is gone. Dan's left in a desert that's slowly fading away, watching as the family he watched die fades into the air, as the sun dissolves, the air gets moist and heavy instead of static-shock dry. And he's left without a person to try and help, without someone else's problems to occupy his mind.

Just him and his grief, a world alone.
