Worst of the season so far although I liked the idea behind the plot and the twist at the end.

Still it was memorable for Buffy starting to counsel (especially Dawn), and Willow visiting Tara's grave (didn't realise we share the same birthday!).

I thought the final fight scene was very lame. And why did Buffy wait so long to rescue Cassie - didn't ring true. Obviously very contrived situation to bring a demon into the story.
I think it would have worked better to simply show Buffy dealing with "normal" (for the Hellmouth that is) teenagers who had no powers. Sort of showing a bit of the mundane but nevertheless important part of being the Slayer.

I assume being bitten by a demon means we haven't seen the last of Peter!
(Nice catch of the arrow!)
