Ok from my squinting at the challenge board I see another challenge rehearsed on the day after the switch called "A Stone's Throw". Based on the pics in the other thread, I think that the RC from the pics above is the "Build it up, Break it down" (or something like that) and the IC is "A Stone's Throw". I think I see "Cat and Mouse" as the RC for episode 6 (the day before the challenge day off on the board).
