Blade VS Buffy Summers - S12-E10
Continuity mistake: Blade and Buffy start to clash weapons, and then get her crossbow and his dual swords in a static bind. When the camera cuts from a close-up to a further shot, Buffy's arm goes from being bent like an L shape to almost straight, and the bangs of her hair become much neater when it looked sort of messy before.
