Spike: “I do remember what I said. The promise, to protect her. If I’d have done that, even if I didn’t make it, you wouldn’t have had to jump. But I want you to know I did save you. Not when it counted, of course, but after that. Every night after that. I’d see it all again and do something different - move faster, more clever, you know. Dozens of times, lots of different ways. Every night I save you.”
