Ho ho. I've pondered most of these at one time or another, especially Giles' bizarre departure from S6 and JM's amazing non-boob acting ability (and yes, the duster is toooo big). I also think I missed the bit where the monk tells Buffy that Dawn is made from her blood, so when Buffy goes on about 'Summers' blood', I was utterly confused. And Willow and Tara are too busy with the spreading beneath the Willow tree to get their hands dirty. Plus, they're students and therefore exempt from anything but pot-smoking.
PS meant to say, your pics of the lake were beautiful.
