Uncle Lao tells his son not to come any closer. He's going to kill him if he tries to take another step. He spits out the guts of a knife at him the night before, and he doesn't know what happened. He says he's not an ordinary detective, and that he'll confess before he breaks his arm. He wants to know if he has epilepsy, and where his drug is. He asks if he can walk around with it, and if it's safe for him to do so. Uncle Lao says he can still get away with it.
