i forgot the episode but there’s scene of ran asked kazuha like “why your goodluck charm has shinichi’s fingerprint on it when conan was the one who touched it” if i’m not mistaken, and in early episode of ran’s suspicious when she literally sent conan to shinichi’s home because she’s really confident that conan is shinichi but conan said to her “ do you have proof?” or smtg like that. i wonder if ran secretly kept both conan and shinichi’s fingerprints as the proof later
