The difference with Buffy and Spike in S6 though was that there were eight episodes leading up to it, and Buffy herself reacted with much the same disgust/disbelief as viewers from S4 would have. Here there seems to have been very little build up (certainly no slippery-slope minor misdemeanours like the Spuffy kisses) and not much logical motivation (for my own part I still don't understand why the Slayers need giant hi-tech headquarters and state-of-the-art weaponry - there was no threat before their organisation and so no need for them to form a properly functioning army).
