The Multi Stage Dynamic of Mole Hunting

The first season of the show is from 1999 and it predates a lot of reality TV wave in the US for example. There's often interplay where like the team that it's the food can like hurt or help the team flying the planes in, you know, in some way or rest versa. The editors are trying to prevent you from identifying exactly who the mall is. It makes sense in a lot of cases for people to draw suspicion on themselves even if they're not actually the mole because you want other people to do good or bad on the quiz or whatever.
