Well, it being 1794..... all of the following questions would really be answered with "Nothing, I still have a very long time til I am even born..... but.. I'll play along.
1. What 3 small items from the ship do you bring with you to the island?
Gun powder, a knife and flint I suppose.
2. Few survivors are left and you can only bring one with you - Who?
The prettiest one. (Its 1794 after all)
3. Are you likely to keep your wits or go insane?
If I were me, Id be pretty crazy to begin with.... I imagine Id keep my wits and what sanity I do have.
4. Do you try to hide from, befriend, or kill the neighboring cannibals?
Depends on their numbers... likely hide until I gained enough knowledge on them to decide if they are indeed a threat (They being cannibals and me not of their tribe Im assuming yes) I would then form a strategy to take them down. However the unlikely even they pose no threat.... befriend.
5. What name do you give your humble tribe of two?
Whatever her name is and my own.... a group of two is not so much a tribe, more a couple.
6. What responsibilities do you dole out to your castaway buddy?
Cooking.... cause I cant.
7. How do you signal for help?
When the time is right, use the flint and the gun powder.
8. You're only eating what you can find - What are you desperately craving?
Tacos, cause.. I am always craving tacos. Whether they are a valid option or not.
9. The cannibals offer a deal: Give up your buddy for immunity or the two of you will be hunted forever - What is your decision?
I'll take hunted forever..... 1) Toro doesn't sell out his friends or his lady. 2) You have no guarantee that cannibals are people of their word.
10. Only the ship's log book and an empty bottle wash up from the wreckage - Who do you write to and what is the message?
If thats all that washes up, how do I write without a pen?
Fine, Id write:
"Ill send an S.O.S. to the world, I hope that someone gets my, I hope that someone gets my..... message in a bottle...."
