I think I have to agree with eowyn - the reason TV Spike has so many layers is that he's had many writers over many years, all of whom saw him a little differently, and all of whom needed to use him for different things in different episodes and different seasons. And Lordy, when those layers were being added, people screamed bloody murder. Spike's been completely ruined as a character at least six or seven times by my count. *g*
