Angel : "It told me to kill you. You were in the dream. You know. It told me to lose my soul in you and become a monster again."
Buffy : "I know what it told you, what does it matter ?"
Angel : "Because I wanted to ! Because I want you so badly. I wanna take comfort in you, and I know it'll cost me my soul, and a part of me doesn't care. Look, I'm weak. I've never been anything else. It's not the demon in me that needs killing, Buffy. It's the man."
