I ALWAYS loved Spike! This is a fascinating comparison of Angel & Spike and analysis of the not rape scene. Buffy - Rant about Spike vs Angel by ~airagorncharda on deviantART with which I completely agree and always have.
I love this scene, because since this is the real Buffy, when she hears this, she sees the kind of man that he can be. And she kisses him. Not a big, fat kiss, just a small, sweet, truly genuine kiss that shows how grateful she is to him.
