^I agree with sk73 (I don't know how to do the cool "I agree" thing... 🙂 )
Aaaaanyway, it took me ages to work out what this thread was talking about. You mean like at the college where everyone starts zooming around fast and Tara talks about watching sponge bob square pants and the next thing we know she's suddenly over at the water fountain?
I just assumed Buffy seemed REALLY slow to everyone else. Remember outside one of the zooming people bump into her and knock her off her feet, must be because she's in the way and moving VERY slowly while everyone around her is walking normally (or to her, they are all zooming around super-speed).
I actually forgot about this scene but I like it because I love scenes with Tara and Buffy away from everyone else. I like the friendship they slowly built in season 6 (especially after Buffy's comments in season 5 that she doesn't "get" Tara). But I feel after all that build up, Buffy's reaction to Tara's death could have been a bit more, like, a reaction!
