It's been a while, but at first they offer you gifts to win your cooperation. You are free to decline or accept any and all of them. What they want from you in exchange is to testify a certain way in the trial. This will determine the alliance.if i talked to all captains and declined all of their alliances is that it? i cant go back and speak with them again? i wanted to hear each guy's offer first
The details will be told again when the trial actually starts, the only important thing is to be done with the tests to join the tribe in 18 days to get the option for best results, after that just help anyone you want to.
There is also a solo route where Sabia tries to go solo without any alliance.
