Cho hears the word demon, but she's not afraid of Cole. Maybe he came back? Maybe someone loved him enough to reverse the damage? Whatever he is now, she isn't afraid. There's no ugliness here. She gives his hand a squeeze, can feel the bones in his fingers, something so familiar and human. He's more than a person, and more than a spirit. He's... unique.

"I don't know-- exactly how I help." What about being compassionate keeps it from becoming warped, other than just feeling it completely, with ever fiber of your being, she could not possibly guess. "But if you ever need it, I will always try." She will try to help, and not just because it's always been what she wants to do - to help, to protect, to safeguard the fragile things in life. She will help because Cole has looked inside her, and tried to take her pain away. She's not at all used to having that desire to nurture reflected back at her.
