The very STUPID episode when Ayumi is "kidnapped"
Almost all Kaito Kid episodes
The London arc that obviously everyone saw
617, was it? The one with the little boy and the guy who kidnapped him them was gonna commit suicide...
The one where they first had Kobayashi sensei as a teacher
There's also the one where Jodie first sees scar akai in the bank... that didn't have any deaths, did it?
oh yeah and the one where Conan tells the Detective boys about ran and shinichi when they were young and tried to solve the code... like someone up there said. i don't remember any numbers of episodes, though
