Ah, now I remember the scene. It seemed a trivial discussion and did not affect me, positively or negatively (obviously, since I forgot about it).
I had no idea that the water main break was filmed on an amusement park set, which is not surprising since I have never seen any such exhibit at an amusement park.
As for the rest of the show, I was bored by the Sweets plot, as well as by the Japanese lady. But I enjoyed the main plot about the murder with the blue disintegrating bullets. Except, the bullet did not work as it was supposed to, since it went through the victim and still had enough energy to cause a powerful explosion of glass particles.
