Entrada, the parallel invasion. A brilliant historical reference to Spanish conquistadors. However Fringe's space cowboys and indians are not all good or evil. As Walternate explained in Amber 31422 nature is not all black or white, it's about balance and imbalance. Therefore most characters are broken and seemed almost extracted from a Picasso painting. It's specially true for Fauxlivia as the shapeshifter told her she would fail because of her human emotions. She cares about Peter, so she can't get the job done. This 8th installment took place right after The Abducted's "Good night sleep" cliffhanger. How would you respond to such a call ? Your partner is someone else. To tell the truth I didn't really like the writers approach, revealing who Fauxlivia is instead of letting Peter and the others find it all by themselves. But in a way it makes sense because it's easy to get blinded by our heart. With such a wicked event I was really wondering how they would develop the parallel arc. An other episodic story ? Far from it ! Entrada's format was quite similar to Lost's The Last Recruit. Fauxlivia and Olivia were both featured and their respective sides were developed in parallel. However the difference is that their universes are linked so their arcs could only collide. The constant switches between both worlds were well rendered and the action never confusing. One minute it's blue, the next it's red. How refreshing and exciting ! The episode was also filled with intense and twisted scenes. One should also shock you and Marionette, the next installment, should decelerate our heartbeat but definitely shaken our minds. Fringe has found its equilibrium. War or peace ? It's coming.
