Sam Winchester: Rowena. I know what you went through and I know how much you lost and I realize how much you want your family back. But don't do this, not like this. This is not you. Not anymore.

Rowena: What happened to me, those were my choices. But Fergus never... It wasn't fair. It's not fair! (Rowena attacks Death with no effect)

Billie/Death: You were never gonna kill him. There was a time you would've, but not now. I can see that.

Rowena: I don't know what I'm doing.

Billie/Death: Sometimes life is unfair and sometimes we lose things and sometimes we make mistakes. And some of these things can never be fixed no matter how powerful you become. Some things just are, and everyone has to live with that.
