SPOILER! DO NOT READ IF YOU HAVE YET TO COMPLETE THE GAME!
So lets talk about the story.
Ive been trying to piece it together for a few days now, and my head is starting to hurt, so I need to write this down.
I may be wrong, may be missing pieces, so please, question and correct me if you know better than me!
Ive kept it as bullet points, because I cant think of any other way to piece it together!
The Primary Universe
Booker Dewitt refuses baptism to cleanse of his sins during the war.
Has a daughter called Anna, but his wife dies during child birth.
He turns to drink and gambling and gets into debt.
Robert Lutece offers to wipe DeWitts debts if he hands over his child.
Dewitt agrees to the deal, but changes his mind at the last minute, resulting in Annas little finger being party chopped off as she goes through a tear.
Dewitt syncs further into depression, scoring his daughters initials into his hand. AD.
The Lutece twins have mastered the ability to travel between universes and meet up after their deaths in an alternate universe.
With the guilt of what they have done to Dewitt, and knowing Comstocks future plans for Anna in Columbia, they offer DeWitt the chance of revenge by taking him into Comstocks universe.
Dewitt is taken to the lighthouse and the game begins.
An alternate universe.
Now it gets complicated, another infinite amount of universes are created at the time of the baptism, and in themBooker DID get baptised, and born again as a new person. Comstock.
He goes on top meet Rosalind Lutece, a brilliant scientist and creates Columbia, as a reaction to his feelings about the war he fought in, and to ultimately seek revenge on the country who sent him there.
Comstock needs an heir to the throne, and somebody to ultimately carry out Columbias master plan, but Rosalinds experiments with tears and multiverse travel leave Comstock infertile, and unable to have his own child.
Rosalind, through the use of multiverses, finds herself in Dewitts Universe, where she was instead born as a boy, Robert Lutece.
Together, Comstock, Robert and Rosalind, hatch a plan to bring Dewitts daughter, who is technically also Comstocks daughter, to Columbia, to carry on Comstocks work when he dies.
Dewitt agrees to the deal, but changes his mind at the last minute, resulting in Anna/Elizabeths little finger being party chopped off as she goes through a tear.
In Columbia, Comstock renames the girl Elizabeth, and with the Luteces discover she has the ability to open and create tears into other universes and times.
The Lutece twins forshadow the return of Dewitt, who will return for his daughter, so Comstock put things in place that will make this almost impossible.
Elizabeth is locked away in a tower, where her powers and abilities are studied and harnessed. A songbird is created to always protect her. Posters all over the city warn of the False Shepherd with AD scratched into his hand.
Comstock kills the Lutece twins because they know the truth of how he obtained Elizabeth and his master plan.
When this is DeWitt understand this, he knows the only way to stop this cycle from happening, in the infinite amount of ways it has, is to destroy Comstock at the source.
He returns to the time and place the Baptism took place, and lets multiple Elizabeths, from multiple universes, drown him.
Things I still dont understand.
The Syphon. Is this the source of the tears? The reason they can happen?
How can Elizabeth create them? Is it because she has crossed from one universe to another? This would explain the Luteces ability to control them.
