Q: Why did the orange shirt guy duck under the sign
A: logistically, that was the only solution i could come up with to get to the right place at the right time. this is one of those puzzles that turns up when you actually get to the set. purple character climbs straight down and looks at the sign. orange character needs to immediately get to a vantage point of looking across the storefronts, while saying the next line. there are many 'bad' ways to do this. orange could climb down and walk directly through purple's line of sight.... this would seem to break purple's concentration. if orange climbs down and walks forward and around back of purple, this goes in between purple and the camera, which is distracting. another possibility is that orange could sort of slide to the side, on the sign, before jumping down. but that seems cumbersome and pointless. i also considered having orange jump off the back of the sign. but it would happen so quickly, i decided that that would look too much like accidental fall. climbing under the sign seemed to be the best way to solve all of this. with the added bonus that maybe he found the extra 'R' letters in the bushes there, under the sign
