In the episode "Karaoke Killing", Someone puts on the main star's coat and puts some shining poison on the right sleeve, and puts it back. Later when he puts it on, and flings it off by grabbing the right sleeve while he is singing, he gets the poison on his hand. After the song, he grabs a rice cake (the poison is on his hand) and eats it. This poisons him, and he dies. 1: If he is going to grab his coat, wouldn't he notice his right sleeve is shining? 2: wouldn't he feel the poison, since the jacket was made of leather?
