Color appeared in snippets of the film to this point -- most memorably a leitmotif shot of the Iguazu Falls, Lai's reason for wanting to visit Argentina and a metaphor for the film's conflicts that becomes decreasingly obvious as the narrative progresses -- but Wong switches entirely to color as Lai drives Ho home from the hospital. His badly injured hands entirely bandaged, Ho cannot fend for himself, so Lai takes him in to help his ex recuperate.
