Yes that is entirely possibly! As some teams do the Fast Forward tasks.. or get left behind or jump ahead due to transportation. Also, if all teams except for 1 or 2 decide to do a different detour that doesn’t have an eye witness taking pictures, they won’t be seen. There are plenty of things that factor into it.
But since there is a team that hasn’t been spot since the beginning of Leg 2 competing on Leg 4 or 5 in france , you have to use process of elimination.
There are 11 teams and 1 goes home each leg unless there is a non-elimination.
So since 9 teams have been spotted since Leg 3, it either means Yoga Moms and Ring Girls are out .. OR there was a NEL in Belgium keeping the Yoga Moms in the running.. OR there wasn’t a NEL until Leg 3 Morocco meaning the 9 teams we spotted in Morocco/France should still be in the running.
If Leg 3 Morocco was an elimination leg though then Jody, Violinists, Debaters, Eaters (or YogaMoms if Belgium NEL) must be at risk as the other 5 teams were spotted in France me therefore made it through Morocco
