It's the moment when they are all in the trial and Kokichi,as usual,insults and lies to everyone while secretly hinting to them a few things about the killer.Suddenly,Shuichi cuts Kokichi off by screaming at him. "Can you stop,Kokichi!? You're not fun or anything! You're just a compulsive liar all the time and you're not helping in the trials with anything,but lies and insults! It's probably that why you're alone! You're always gonna be alone!!" (It's all canon, you're Kokichi.)
