I would ahve loved to see Spike interact more witht he Scoobies. The whole Anya/Spike dynamic would have made a great friendship. They're both demonic sort of people who had their hearts broken. It's a wonderful relationshop they could have had.

Cordy/Xander made me laugh my ass off. Xander/Anya broke my heart. He ran the moment something remoktely bad happened.
