Visible crew/equipment: When Budd is being fired by his boss at the strip club, you can see the boom reflected in the boss's sunglasses.
Visible crew/equipment: When they show Elle's face from inside the toilet you can see Plexiglas between her face and the camera. You can also see a round outline in the Plexiglas that I presume is the reflection of a camera lens. (01:16:20)
Chosen answer: The way she talks to Budd as he lies dying, seems to indicate that she has disliked and hated him for years, plus the fact that she feels that he was not "worthy" of killing Kiddo (seeing how Kiddo was a fantastic warrior, while Budd is an alcoholic hick). However, it would be difficult for her to get close enough to kill him earlier, as he would not buy any excuse why she just came visiting. But when Budd actually invites her over, she gets a chance to get back at him, and in the same while take the credit for killing the Bride and retrieving her Hanzo sword for Bill. Vengeance and personal gain in one swoop.
