Continuity mistake: Man-wol pours some stuff to drink into a bowl and then picks it up with her right hand. There is a bandage wrapped around her hand and some of the bandage can be seen dangling freely over her hand in the shot of her picking up the bowl. In the next shot, the piece of bandage dangling from her can't be seen. (00:03:15)
