Continuity mistake: When Dawn was at the house, she had a grey top and a red skirt, but outside, she had a red top and black pants.
Continuity mistake: In the alleyway scene after the real Buffy kills all the Hellions (biker demons) and runs off, one of the Hellions can be seen getting up behind Xander. We then see a closeup shot of the Hellion opening its eyes while still lying on the ground and then they stand up and sneak up behind Xander again.
Continuity mistake: When Spike is looking out the window at the demons rampaging in the street outside Buffy's house, Dawn can be standing behind him with her hair trailing down below her breasts. In the next shot, when Spike pulls her away from the window, her hair is pulled back behind her shoulders despite her not having moved. (00:53:10)
Continuity mistake: Buffy's shoes change from being nice shoes, to runners (e.g. When Buffy climbed out of her grave, she had nice shoes, but when she jumped over the fence, she had runners on).
Continuity mistake: When Buffy sat down on a car and set off the car alarm, she didn't have any dirt on her hands and only a little bit of blood, but in the next shot, there was a lot of blood and dirt on her hands.
Answer: She has superpowers, ergo fast movement. The reason she outruns him so easily in "Touched" is that she stops trying to actually fight him and just dodges instead.
