A comedy delight which, surprisingly, comes from the pen of Rebecca Kirshner rather than Jane Espenson. Wiping the Scoobies' memories allows for much hilarious confusion, even if conclusions about everyone's relationships are drawn somewhat hastily in order to speedily advance the plot.
Highlights include the disastrous spells in the Magic Box - the Jason and the Argonauts-esque skeleton and a plague of bunnies - and the sight of a tweedy Spike getting rather confused over his parentage.
To top it all, Giles has left Sunnydale. Again. For good. We'll miss him lots. However, we have a sneaking suspicion that as Tony Head hasn't quite fulfilled his quota of ten episodes for season six, he'll be back when we least expect it.
