Ok so as I understand it, Comstock is what DeWitt would become had he accepted God, and Booker is the opposite side of that coin. So how do the two exist simultaneously within the same reality? Like how Slate talks of DeWitt's prowess in the war at Wounded Knee, how did both versions of the same entity(being DeWitt) fight in the same war in the same reality?

EDIT: And yeah, change the thread title and put a spoiler tag.

Dude dude dude dude. Spoiler-ish-ness in the thread title and no mention of spoilers in the body of the first post. Nu-uh son. Not cool.

A - Spoilers of the game's twist right there for everyone to see. Oh well, it'll save em $60.

B - in this multiuniverse, it doesn't matter if 2 of the same person (from different universes) coexist at the same time. Look at the Luceces'. 2 of the same person coexisting. Also, Comstock DID fight in Wounded Knee. Slate just didn't know he was Dewitt.

Somebody change the thread title, this is uber spoilers.

The Booker you play as was brought to this universe by the Luteces. It's why he doesn't know about flying city of Columbia.

Yup, Columbia doesn't exist in his own world because he never got baptized.

I can understand not considering the title a spoiler, it has been well established that Bioshock Infinite will deal with alternate realities, given that tears are doorways through to alternate realities.

@gontlet: I really think you should delete the title of this thread. It spoils the game with the title.

The way I've seen it, the two Bookers existing in the same universe is contingent upon them not knowing that they are actually the same person. There were a couple of sequences when the tears first got introduced where we saw people that just sort of stood around, and I remember Elizabeth mentioning that they were aware of both realities. So I think that sort of cripples you in a way, hence why Booker's nose starts to bleed every time he gets close to remembering/realizing things about Comstock. If you remember both versions, you can't really make sense of either.

@sloc234: Comstock was fully aware that Booker was him from another dimension. That's the whole point to him stealing Anna from him. It was the only way to have a child that was still "his" despite the fact that he was sterile. Similarly Rosalind Lutece was fully aware of who Robert was after bringing him over, but Robert's memories gave him some difficulties. The confusion came from the fact that Booker and Robert were out of dimension. Comstock and Rosalind were 100% ok.

I changed the title.

@starvinggamer: So do we know that 19 years passed in Booker's dimension before he was brought to Columbia? Clearly 19 years had passed in the Columbia that Booker was brought to, but theoretically the Luteces could have taken Booker from his dimension at any point in time after the Anna-grabbing.

Just a quick question, when exactly is dimension B Booker dragged into dimension A by the Lutecces? It's never shown in game (for good reason I guess) but is it while Booker is passed out drunk or something? I assume it is....

@killacam: It would appear so, as they would want to maintain chronological consistency and avoid overloading Booker's brain any further. That is why his memories rewire themselves to believe that Robert Lutece came to him in 1912, not 1893, offering to erase the debt. During the ending sequence Elizabeth mentions that after losing Anna through the portal, he drank himself into a 19-year stupor before stepping into Dimension A.

@vinny_says: The Luteces opened a portal in Booker's office and offered him a chance to rescue Anna. He went with them but was hit by trans-dimensional amnesia. He comes-to on the boat where Rosalind hands him the box with enough clues to push his mind in the right direction as it struggles to fill in the blanks with false memories.

Right, that makes sense. I guess I missed/forgot about that line due to all the mind-bending revelations.
