Gonna talk about final task here... While i really hyped for the final task, and claimed that it was one of the best final task of all time in TAR history, there was a flaw about this task (beside peach's point "properly assemble plane' thing)
You have recognized all stickers that representing 12 legs, and one of them is a magnifying glass (Prague). And the magnifying glass was representing A roadblock in Prague when the supervisor checked their answers with it.
The problem is, not all of the final task doers did the RB, and the one was Henry. I could have sworn that thing Henry changed the piece that cost his chance of be a winner was that magnifying glass, since he didnt the RB back then, so it would have confused him even more than other racers.
Also Jen on r/TheAmazingRace admitted that magnifying glass was really made them confused since not it wasnt part for the RB at all (i mean yeah it was used as decotation for checking their rb answer tho), but also came from another task in Belgium (Diamond task) which was a detour(altho it was solved by reading the detour task)
My point is they could have gone with all stickers that not only representing each legs, but also be visible with other member teams, especially non participating RB member teams. I mean, Henry and Evan could have discussed it before Henry started to assemble the plane's part, but idk if it was allowed, but crews should have prevented from a final task doer being an disadvantaged, since it was a literally final task, and it would be unfair.
That, however, is my only complaint on final task, and i still happy that they made that final task. Confindently, the best final task ive watched since 12 and 21.
