I’m gonna go ahead and point out that I haven’t watched the season 2 finale of Fringe yet, but I mostly see where things are headed, and I’ve noticed a lot of parallels between that show and BioShock Infinite. Allow me to explain.
Walter Bishop is Booker DeWitt / Zachary Comstock
Walter is a father who lost his son. Comstock is a man who never had a daughter. Both of them create (or commission) machines that allow them to cross into a parallel universe and kidnap their own child from an alternate version of themelves.
The fathers of the kidnapped children, “Walternate” (as Walter calls him) and Booker, are both pulled into the other universe by allies seeking to help them reclaim their children and defeat the evil kidnapping alternate.
Basically, by rooting for the Walter who appears in most of the series, you’re rooting for Comstock. The alternate Walter who is initially pulled into this world on the bridge (not the one that’s built in season 4, the actual physical bridge over water), who we percieve as the villain, is actually the Booker of this story.
Peter Bishop is Elizabeth Comstock / Anna DeWitt
For the first season and a half, we see Peter as a native of the main universe, much like anyone living in Columbia would have viewed Elizabeth. In the second half of season 2, we finally learn (after much foreshadowing) that this is not the case, and that Peter was actually born in another world to another version of the same man. That makes him special.
The Observers are the Lutce “Twins”
Interested third-parties able to move between time and space freely? Check. The Observers and the Luteces both take action when needed but for the most part are content to simply watch the action play out in front of them, dropping occassional hints to the main players about what needs to be done to solve a problem.
“Tears” look identical in both stories
The openings between worlds (whatever you want to call them) actually look the same between BioShock Infinite and Fringe. The flickering-glimmering-hologram look is nearly identical in both cases.
Bonus: A female character loses part of her body in a closing portal
When Elizabeth is kidnapped by Comstock, part of her finger is cut off by the portal as it closes. When Walter is initially traveling to the alternatve universe to take Peter, Nina Sharp’s arm is caught in the portal and eventually amputated (though she explains to Olivia in the first season that she lost the arm to cancer).
Double bonus: Walter’s wife was named Elizabeth
Do I even need to say more than that?
So there you go
A father who wants a child creates a machine that allows him to travel to another universe, kidnaps his own child from the other world, someone loses a body part in the closing portal, and the father of the missing child comes looking for his kid. All of this sets a series of events in motion in which flickering objects from another world precede an all-out war between universes, which is observed and sometimes aided by mysterious individuals with the ability to pass through time and space at will, and who may or may not somehow be related to each other.
Did I just describe BioShock Infinite or Fringe?
(Answer: both. It’s all about perception. Heads, tails. Life, death. BioShock, Fringe. Two sides of the same coin, and all that jazz.)
