Buffy and Spike are reunited in Chapter 7.
Spike freaks out and Buffy leaves him to go back to Scotland in Chapter 13.
Some of you might recall my discussing authorial intent and meaning in fic. I did not intend this to happen. That one of the highest moments for Spike and Buffy occurs with lucky number 7 and the ugliest moment between them occurs at unlucky number 13. I didn't intend it, but I think it's kinda awesome. Hee!
