Image repetition is also directly acknowledged in the plot, in a scene where Dae-su, following clues left by Woo-jin, visits one of his old high school classmates at a hair salon. While he gets information from her, a young woman enters the shop; Dae-su, who moments before was shown to be strangely attracted to her classmate’s exposed knees while she was trying to recall a name, turns his attention to the young woman’s knees, shown in a close up (figure 13). Sud-denly, the sight of the girl’s knees triggers a memory in Dae-su about an encounter he had in high school with Woo-jin’s sister, introduced in a flashback also with a close up of her knees (figure 14). Dae-su could not remember this encoun-ter until he saw the girl’s knees, suggesting the possibility that he might have blocked this memory of her because of the psychological trauma he associated with this encounter. This point is reinforced when Dae-su is shown going back to the room where he witnessed Woo-jin and his sister having their incestuous affair. It is only when he revisits the actual spot where he spied on them that he is able to remember the event and finally reveal the reason for Woo-jin’s revenge.
