The Bioshock Infinite ending may have been confusing for some people; it’s full of time travel, multi-worlds and other crazy concepts that are sometimes only mentioned in voxophones. So I’m going to help you out a little bit and answer some of the hard to understand questions and concepts behind the Bioshock Infinite ending.


Before getting to the meat of the ending we have to lay the ground work for how the Bioshock universe works. Throughout the game Elizabeth has been opening tears through space and time. Near the end of the game we get to travel through multiple tears that take us back to Bookers past and even to Rapture. It is extremely important to remember that Elizabeth can not only travel through time, but space as well. The Lutece twins are also very important to the plot because they are pretty much the reason the entire plot occurred at all. If you need a refresher on the ending, the video is below.

The Multiverse

To understand what is actually going on in Bioshock Infinite you need to understand the basics of multiverse theory. Multiverse theory was first coined by William James in 1895 and suggest that an infinite number of universes exist that are all separate and unique from each other. Basically every choice you ever could have made exists in another universe. This is shown in detail during the ending when we see one universe where Booker refuses the baptism and another where he accepts it. This creates two different universes. When Elizabeth takes us to Rapture she describes it as a door, each of the stars in the sky are doors to another world. We then see a never ending string of towers stretching to the horizon each of them a different universe or as Elizabeth describes them “…Doors to everywhere.”

The Lutece Twins

The Lutece are theorized to be the same person from different universes. They share many similarities and are always seen together. The twins are responsible for traveling through the multiverse and putting the events of Bioshock Infinite into motion. They are also seen throughout the game helping Booker on his mission and offering advice. Robert Lutece possibly exists in the original Bookers universe but it doesn’t explain the gender difference between himself and Rosalind. What we do know is that Robert isn’t from the same universe as Rosalind and that he came to her universe at some point in time.

So Elizabeth is Bookers Daughter?

Yes, Elizabeth is actually Annebelle Dewitt, Booker’s daughter who he sold to Robert Lutece in order to settle his gambling debts. At the last minute Booker changes his mind and tries to take his daughter back. The door closes and cuts part of Elizabeth’s finger off. Booker then brands himself with the letters “AD” on the back of his right hand; AD stands for “Annabelle Dewitt”.

How come nobody knows About Columbia in the world below?

If Booker never went through with the baptism he never created Columbia, thus it never existed; which is why when Elizabeth asks if people below ever talk about it, Booker says no and that they must have just forgot. Truth is they never forgot, it just never existed in that universe.

Why doesn’t Booker remember this event?

In a voxophone voiced by Rosalind Lutece, she talks about travelling through multiverses and the effects on the mind. Rosalind Lutece says that “The mind of the subject will desperately struggle to create memories where none exist…“. During the ending we see a scene where the Lutece twins are dragging Booker through a tear. During this scene Bookers mind is re-writing itself and creating memories that don’t exist in order to assimilate itself within the new universe. Robert Lutece even exclaims that he lived it, meaning that he isn’t part of that universe either but instead comes from another, meaning his memories were also re-written at one time.

Why are there tears in reality all over Columbia?

During the game we see a bunch of tears in space time all over Columbia, citizens even comment on them and theorize on what they are. Because of the constant moving between universes, the space time continuum is being re-written and distorted. Thus tears in the fabric of space time are occurring throughout the city.

If we assume that Booker and Comstock’s paths diverged when the baptism choice was made, and they were the same person in the same timeline prior, how does that explain the Luteces?

We have to remember multiverse theory when it comes to this. Sure Booker and Comstock are the same person that made a different choice but that doesn’t really have anything to do with the Lettuces’.  The Luteces are the same person from different universes but you have to remember that there are an infinite number of universes that are all different, that means in lots of those universes Rosalind Lutece is actually Robert Lutece. Rosalind opened a portal into another universe and found Robert.

What was the point of the game if Booker dies at the end?

Remember that the space time continuum is being ruined because the Luteces were traveling between universes. This means that the space time continuum is in disarray; the entire plot was an attempt to correct what was happening and prevent the space time continuum from tearing itself apart, which is why Booker had to die in order to ensure that Comstock never created the city, setting the universes back on track.

Who is the Booker at the end after the credits? Or “Why is the Booker in the end game credits questioning if Anna is in the crib?”

This question is a little tricky to answer because it is all interpretation. This booker could just be in a universe where nothing ever happened but that doesn’t really explain his questioning on whether or not Annabelle was in the crib. I think the best answer for this question is since the universes were corrected, the space time continuum was essentially reset bringing booker back to life before he sold his daughter.

why did Comstock have to imprison her at all? at what point did the Lutece twins give the baby to Comstock?

Elizabeth has the ability to open tears for a short period of time, if her powers were fully realized she could have upset the space time continuum.

how did comstock know Booker would go to Columbia? The Lutece twins told him they brought him there?

Comstock might have known he would come, he was a prophet afterall. The lutece twins were also helping him use the machine which is why he aged and became sterile. They were using the machine to see the past and future, thus Comstock knew Booker had branded himself and he knew he would come.
