We saw Jaime/Cara wandered on the street with the gnome and without any opera make up, so does that mean the find-the-gnome task happen before detour, and they have to carry the gnome in the entire leg? Or do Jaime/Cara clean the make up after the detour?
For the other task, really have no idea what Tammy/Victor would do, but I think it is also related to Chinese Opera and probably takes place nearby, otherwise it would be unfair to set the U-turn close to one detour.
