"I shouldn't be alive but I am. I don't know how I fit into the world anymore, either."

It's not any new information that Cole doesn't already know, but Ben wants him to understand, if he can, that he's not alone in the way he feels. Not being sure what he is or where he belongs or even what he needs. Ben knows those feelings. And he thinks, even for a spirit, maybe it will help not to feel so different, so alone.

Even if people aren't usually kind to spirits, Ben is damn well going to be. He's made up his mind. So he smiles, when Cole thanks him for his words and acknowledges they are hard for him, and says:

"Anytime."
