Hmmm, Jill and Thomas, Brook and Claire, and Michael and Kevin's departure time were shown, right? While all others just sporadically popping on their way to Avtovo Circus. The three teams above were the only groups of people who did not try the Classical Music detour option, while Nat and Kat, Nick and Vicki, Gary and Mallory, and Chad and Stephanie did. Maybe it's indeed that side of the detour were the production faulty.
