I really love this moment. I think we get so wrapped up in the title of the episode, and how much it connects to Buffy/Angel and Angelus, but this is the moment that Spike breaks. Right here. Look at his face. THIS IS A VAMPIRE. THIS IS A SOULLESS, EVIL VAMPIRE. But he is the normal to Drusilla’s crazy. Together they make one person, but apart she is the crazy in everyone, and he is the sane. He’s almost her humanity. And what a human emotion he’s experiencing. He’s so jealous and angry and afraid in this moment that he actually plots to betray Angelus… because he only has eyes for Drusilla.
