Scene of Violet getting out of the tub nude to service her second trick.
In the most widespread version today, due to a different viewing ratio, the private parts are not visible, the scene as described is present only in the uncropped version.
Afterwards, her brother walks in and whistles at nude Sophie while she's in the tub. She tells him to get out and he says "Why so modest now, you let the whole world see you naked before" refering to her at the beach.
