Foreshadowing / BioShock Infinite

Beating BioShock Infinite and playing through again is startling; almost the entire game is filled to the utter brim with foreshadowing that makes sense on replays or analysis.

---

• When Booker first arrives at the tower, he sees a water tub with "Of Thy Sins Shall I Wash Thee" over it. Booker mutters under his breath "Good luck with that, pal." This doesn't become symbolic until later when you learn about Booker's rejected baptism. And, of course, the baptism that shortly follows sees Booker almost drown...
  • With some knowledge of The Bible, the presence of the water tub right at the entrance is another hint at Comstock's perspective on baptism. Pontius Pilate made a show of denying any responsibility for Jesus's crucifixion by washing his hands in front of the mob. Comstock's view on baptism as a justification for his atrocities is basically the logical extreme of Pilate's symbolic act.
• Booker asks the man in the boat whether someone will meet him at the lighthouse. The man in the boat says he hopes so. Turns out that Booker meeting Elizabeth and resolving all these quantum shenanigans is their plan. The game even ends after an extended sequence involving our heroes and that lighthouse, as well as a few dozen alternate versions.
• The blind preacher who baptizes Booker when he enters Columbia is the same one who tried to baptize Booker after Wounded Knee. The Booker we know refused the baptism; the one who accepted it took the name Comstock. For extra irony points, the preacher's first words to the player are "Is it someone new?" Answer: Nope!
• After the blind preacher baptizes Booker at the beginning of the game, which leads to the first "gives us the girl and repay the debt" flashback, Booker comments that the blind preacher might drown someone. During the ending, Booker is drowned to death by all the possible versions of Elizabeth at the same place where Comstock was baptized by the same preacher.
• Midway through the game when Booker is questioned by Elizabeth about Columbia, he says he never even knew about it before arriving. This is because in his universe, Comstock (and therefore Columbia) didn't exist.
• When Booker first enters the Monument and finds the room with the Siphon, Elizabeth is humming Everybody Wants to Rule the World. Hmmm...^note If you didn't know that the earlier songs you may have encountered in the game ("Goodnight Irene", "God Only Knows", etc.) were actually anachronistic, hearing this is sure to clue you in that someone's clearly messing with time. On top of what we learn about the dark future Elizabeth.
• Songbird's eye cracks from the pressure of being underwater when it seeks out Booker. Note it's a relatively shallow depth, so when Songbird ends up at the floor of the ocean...
• When Booker washes up on Battleship Bay he calls Elizabeth "Anna", which she refutes. The likely assumption is that she resembles his lost wife, who he mentions later in the game. Towards the end, it's revealed that she actually is Anna, given up by Booker to pay a debt. Maybe he subconsciously recognized her?
• While Booker and Elizabeth are walking through Battleship Bay a hot dog vendor offers a hot dog to Booker and his "daughter". Later we find out that Elizabeth is in fact Anna, the daughter he gave up.
• The Columbia goon who gets Elizabeth to confirm her identity, so the Columbian Police can ambush Booker asks Elizabeth if her name is "Annabelle". She refutes this, too.
• In one offhand conversation, Elizabeth may ask Booker if there's a woman in his life, and he replies there used to be, but she died giving birth. Elizabeth inquires if that means he has a child, which Booker only replies with a quiet "...no." The implication on a first playthrough is that the child died along with Booker's wife, but note that Booker doesn't explicitly confirm that that's what happened.
• After being forced through a gauntlet of Slate's men, Booker denies the old soldier's claims that he's a hero, and Slate responds "If you take away all the parts of Booker DeWitt you tried to erase, what's left?" The answer is: Comstock, that's what's left.
• Throughout that entire area, Slate is constantly deriding Comstock because he believes that he was never the war hero he claimed to be. Slate is Right for the Wrong Reasons.
• If Slate is given a Cruel Mercy by being left alive, Booker and Elizabeth later find him in the bottom floor of Finkton's police station, catatonic from being lobotomized. Elizabeth, in the Bad Future, suffers this fate, but unlike Slate, turns just like her father.
• Shortly before the nature of the Luteces is revealed, Rosalind can be seen posing for Robert, yet he's painting a self-portrait.
• The true nature of the Luteces, the same person from two different universes, foreshadows that Booker and Comstock are just like them, except they're separated not by a single chromosome, but by a single decision.
• In the bank, Elizabeth says Comstock's tithe is a whopping 50% of everything that comes in. Booker quips that he needs to get a job in the prophet business. Comstock, as it happens, is an alternate Booker who did just that.
• Early in Columbia, the very first Voxophone Booker may find is Lady Comstock saying "Love the Prophet, for he loves the sinner. Love the sinner, for he is you." Accurate in more respects than you'll likely realize the first time you hear it.
• When you meet Elizabeth face-to-face for the first time, the huge book she was about to smash your face with is titled The Principles of Quantum Mechanics.
• There's one particularly telling dialogue between the two as they go to deal with Comstock.
  Booker: I won't just abandon you!
  Elizabeth: You wouldn't. Would you?
• When you board Comstock's zeppelin during the endgame, Comstock gets on the loudspeaker and counsels Elizabeth to "Look at DeWitt, child. There's something about him that you just can't put your finger on." This is arguably Black Comedy, given that Elizabeth is missing the tip of her pinkie... but after you find out why it's gone (snipped off by a Portal Cut when she, Anna DeWitt, was taken away from her father Booker by Comstock), it takes on another dimension entirely.
• Everything Comstock says to Booker. Comstock says Booker has a tendency toward self-destruction, and he's right in any reality - whether it's Booker drowning Comstock, Comstock abusing the Tears until he became sterile and sickly but absolutely at peace in the belief he would soon go to God, Booker gambling and drinking his life away, Booker allowing Elizabeth to drown him, and Comstock allowing himself to get beaten and drowned. Even the bounty hunter Preston E. Downs' audiolog subplot qualifies. Alternate universe Booker translates a Sioux kid, so Preston decides to target Comstock, his employer. And Preston only ended up in that situation because Comstock hired him in the first place.
• Everything Booker says to Comstock. Blind with rage, howling at Comstock for all his crimes against Elizabeth? Nothing but a pretext for Booker to express his profound self-loathing. Everything he says applies to him as much as Comstock. In that moment, Booker subconsciously wishes he could strangle and drown himself.
• Following the first jump through to an alternate reality and finding Chen Lin alive, but disoriented to the point that he's unaware of anything happening around him, Elizabeth comments.

  Elizabeth: Maybe... he also remembers not being alive. What would you do if that happened to you?
  Booker: I don't know.
  It already did.

• Before that you encounter guards you had just killed in the previous dimension. They're disoriented, and all have nosebleeds. Chen Lin is shown to have one as well. After your second hop, Booker gets a nosebleed...
  • After Booker kills Comstock, Booker's nose begins to bleed again.
• Comstock's prominent biography display in the center of the Hall of Heroes gives his birth year as 1874. Anyone who pauses to do the math on that will realize he's actually much younger than his appearance would indicate.
• In the universe(s) where the Vox successfully rebel, you come across a sobbing, hysteric woman who is deathly afraid of leaping onto a barge, and possibly falling to her death below, while her husband tries to get her to take the risk, or she'll be left behind, which would be worse than falling to her doom. When the barge leaves, it's implied she did make it. When Booker's forced to relive his attempt to get back his daughter from the Luteces, Rosalind is desperately trying to convince Robert to hop the small and unstable hole into the universe, and Robert is frozen up in fear and saying he can't go through with it, what if the gap closes and he's stuck between universes, or chopped in half...?
• The song that Fink sings at the Raffle is "Goodnight, Irene". One of the lyrics contains "Sometimes, I've got a great notion/To jump in the river, and drown..."
• When Daisy Fitzroy is about to kill Fink's son, she says "You see the Founders ain't nothing but weeds. Cut 'em down and they just grow back. If you wanna get rid of the weed, you gotta pull it up from the root. It's the only way to be sure—" right before Elizabeth plunges a large pair of scissors into her spine. In the end, this is exactly what Elizabeth and Booker do; they pull Comstock out by the roots to make sure he can never have existed.
• As can be seen on a film projector in their conference room, the Fraternal Order of the Raven have begun to theorize that Comstock is hiding mixed Native American / white ancestry, just like Booker. (This revelation also comes purely as dumb luck, given that they "proved" it using the quack science of racial phrenology.)
• The voxophones in general are fountain of these. In particular, in one of the the voxophones has Slate mentioning how Booker was called the White Injun of Wounded Knee due to all the indians he killed and another voxophone mentions that Booker speaks Sioux. A later voxophone has Comstock ranting about how a sergeant once insinuated that Comstock has Native American ancestry. To prove that it was a lie, he burnt down Indian teepees. Weird how two vastly different characters have similar pasts.
• When Booker and Elizabeth confront Comstock on his airship, Booker drowns Comstock in a baptismal font, foreshadowing his own drowning later in the baptismal water.
  • The baptism being his fate (and Comstock's) is foreshadowed from before he even gets into the fancy chair.
    Booker: (on reading the placard before the baptismal bowl in the lighthouse stating, "Of Thy Sins Shall I Wash Thee") Good luck with that, pal.
• One of the very first voxophones you encounter features Comstock pontificating on baptism, saying that one man enters the baptism and another emerges. He wonders, "Who is that man in between?" It turns out that Comstock and Booker are the same man separated by a single choice: one who took the baptism, and one who didn't. At the end, one version of Elizabeth says that he's Zachary Comstock, while another insists that he's Booker DeWitt. He corrects them, saying that he's both.
• When you come across the Luteces playing a piano following the airship crash in Emporia, you can hear them bickering about one note that Rosalind keeps messing up: the "G". Elizabeth's freakout over them playing the song and causing Songbird to come and find them gains a whole new meaning when you find out the sequence of notes needed to call him to help you.
• Comstock calls Booker the "False Shephard". So who's the real one? Comstock himself. Especially since Elizabeth is called the "Lamb of Columbia". This implies that he's a thematic counterpart to Booker. He is, but he's also a much more literal one.
