Wilkin reminds me of an old student friend of mine, who gave the impression of being permanently amiably half-asleep or stoned. When he proposed to another friend of ours, we were primarily astonished that he'd stayed awake long enough.
Comedy demands that someone, at some point, recruits Wilkin as a traitor, surely?
I can't get past how piss-poor the tasks are. Surely it wouldn't necessarily cost too much to evolve better ones? Even if we dispense with helicopters and lasers or expensive things, or terribly athletic things that would involve too much set up and safety checks.
Aren't there obstacle race sets from Ireland Fittest Family they could borrow or something?
Just orienteering-type running around in the woods following a map to get to certain coordinates, but where the controls you have to get a clue from are alive and masked and can run away from you.
Blow up giant gym balls and try to get them through an obstacle course.
An endurance challenge like Survivor, where you have to stand on something with your hand on the prize for as long as you can.
A blindfold challenge, where a blindfolded person is guided to find clues by someone at a distance giving them directions via an earpiece or loudspeaker.
Or you have to get buckets of water from the river and throw the water into something to get a floating key or clue high up enough to reach in and grab it.
Scaled-up game of Battleship.
Even something really simple where there's a selection of objects in a line, and then each person has to run back to their own spot and put the items in the right order.
(I'm stealing lots of these from Survivor, especially in the season where 9/11 meant they had to switch locations at the last minute and had to invent simple challenges.)
Obviously, some people are fitter than others, so you need a mix where some people on a team do the running and others do the puzzle-solving.
I think they should also have separate shield challenges.
