Blade VS Buffy Summers - S12-E10
Continuity mistake: Buffy fires an arrow from her crossbow that travels down the length of the bar, going through a vampire and then it gets caught by Blade. Then, in the next shot, as Blade starts to use the arrow to stab more vampires, the camera shows down the length of the bar towards the direction Buffy just fired it from, but she's not there. Note the stage lights behind her in the first shot for orientation. (00:18:47)
