"How was I supposed to know what you'd think. Just when I think I have you figured out, you go and flip flop on me," Buffy should have been highly familiar with most, if not all, of Spike's defense mechanisms by now, so his response shouldn't have come as much of a surprise. He wanted to keep going and rant a little more, but when she called him a champion all the fight went out of him as it occasionally did around Buffy and he couldn't help but suddenly become very interested in his old, worn boots all the while a smile threatened to turn up the corners of his lips as he recognized the words she was quoting at him.
Oh, they could have some epic arguments and fights and it was stupid to think that they wouldn't in the future, but right now it didn't seem like that was the route they were going down and Spike would be lying if he said he wasn't glad. Lifting his head, he met Buffy's gaze again, "Keeping a log of everything I say now?" It was then that he allowed her to see his smirk, "Am I gonna find a shrine to me in your flat next?" No wait, that's what he'd done.
