Hi im new to this forum. I really need help finding this episode. Ive seen it before but i wanna watch it again cause it was one of my favs but i don't know the episode number. I can't remember what the case is about but i clearly remember Conan/Shinichi telling her the deduction through the earring cellphone. She is fine and confident throughout the whole deduction until he tells her the culprit. At this time she bursts into tears and reveals him/her. Thanx for the help in advance.
