1. If what the women we know as "Mother," is telling the truth, there is nobody on the Island, who's roots or ancestry is truly from the Island.
2. I think Mother may have brought Claudia's ship to the Island.
3. Claudia's first child is named Jacob. However, since she did not know she was carrying twins, she was not able to pick a name for her second child. The second child would simply be known as "Brother."
4. It looks like the board game is a precursor to Backgammon.
5. Mother tells the young Brother that he is special. Does she believe him to be her replacement at this point?
6. According to Mother, death is something Brother won't have to worry about.
7. Mother is the guardian of the Source. It's essentially the same light that exists inside of every human being. The people who come to the Island, are looking for the Source.
8. Why could Brother see Claudia, but not Jacob?
9. Is Claudia the Monster or a Whisper?
10. Why does Mother believe that the Others are bad?
11. So 30 years later, Jacob and Brother still meet and play their game. Brother is using them to find a way off the Island.
12. And it would seem that he has found his way off. Brother was the one who dug the many wells throughout the Island, investigating the magnetism.
13. The way Jacob told Mother about Brother's plan, it's clear Jacob was spying for her the whole time.
14. The way to leave the Island: build what we would learn to be "the frozen donkey wheel." It uses a system that channels the water and the light, and when turned, it will enable the user to leave.
15. Drinking the wine is the ceremony that allows one to become the protector of the Island.
16. Entering the light makes one "worse then death." Did Mother even know what could happen?
17. So by herself, Mother torched the entire settlement that was on the Island. What exactly did she do?
18. In his rage, Brother killed Mother, in retaliation, Jacob dragged Brother into the light, killing him as well, and releasing the Monster. Jacob returned Brother's body to the cave, placing it beside Mother, and the two would soon be known as Adam and Eve.
19. Now, what I have to say next is speculation. The Monster, is NOT Brother. In the few times we've seen Jacob and the Monster together in events prior to "The Incident," the Monster appears in the form of Brother. Notice how Jacob refers to him as "My Friend" and not "My Brother." It is clearly a different entity, which preferred to use that form when it talked to Jacob.
