The brick was easy. Just have someone in the city with a brick and send them the location as soon as it’s determined during the performance.

On the letters, I’m curious if the people who got them determined whether they were actually written by the person they thought they were from. If yes, I’d assume once people bought tickets, some were selected and someone reached out to their social networks to see if anyone wanted to send them a letter. If no, for a whole lot of people, it’s pretty easy to garner some intimate details of their life from their online presence.

As for the end, he could have a transmitter anywhere under his clothes to receive code. He also could be wearing infrared contacts to see invisible ink and his staff could have been putting up labels for rows throughout the performance somewhere within his line of sight. Honestly, closing on this one kind of hurt my enjoyment of the show, as it seemed to so transparently be a ‘trick’ that the people getting emotional that he knew the label they picked came off as a bit silly. Delgaudio’s display of emotion also took me out of it, as it was so clearly acting. I don’t care how sad a story is, you don’t naturally cry the 500th time you tell it.
