Detective Conan - Season 1 Episode 740 : Bathroom Where Ran Collapsed As Well (1)

As Conan and Ran are waiting for a meeting with Eri, they meet Sera, who is investigating Rumi Kitao's boyfriend, Kenya Settsu, about adultery. Thinking that Kenya will make a move upon seeing Ran, Sera has Conan and Ran approach the couple upon the pretense of needing a meal. However, Kenya doesn't seem to be interested in Ran and asks Ran to accompany Rumi to wake Waka, Kenya's ex-girlfriend. Rumi and Ran have to open Waka's apartment with a key when no one answers. Later, Ran finds Waka on the bathroom floor, but she collapses herself due to chloroform in the air.
