I've known men like that. Well -- no -- not like that. There aren't many men like Guy. But...name-changers. Name-makers. Men who've abandoned whatever it was they were called.

[ liam became angel; william became spike; jack, who likely had no surname to begin with, became sparrow. buffy was never so good at losing her name the way they were. the only time she'd tried, she'd merely swapping in her middle name. anne.

I think I prefer nicknames, myself.
