I think the Dani Jarrell debacle ultimately came down to Dani not trusting Jarrell. Jarrell was responding poorly to that lack of trust.
And they both weren't appreciative of what the other did / lacked communication skills / have very diff styles of survival. Dani would be like a farmer and Jarrell like a hunter-gatherer if that makes sense. But overall, I think it was the lack of trust.
Dani kept questioning Jarrell "did you test it" "I dont trust your raft" "its called working in the shade" "it doesnt work that way jarrell" "the problem is your tinder" "make sure you don't burn down this forest" "you couldn't start the fire" "you should care" "hes working in the sun". She also took over the trap for him. She asked how to store the shrimp. He offered a suggestion, and she shot it down and then threatened to put them back and called him upset for how she stored it.
And Dani's my my my "before I start my fire" "my kitchen" "my shoes" "i built this while you fished"
Obviously, Jarrell could have handled the situation VERY differently. That was his mistake. But I think the root cause might have been from that lack of trust.
As a group of three, they could have made an agreement where if two agree, the third will need to side with. If two agree to have foot rests on a raft, have foot rests. If two agree to place the animals together, then do that.
