The fourth season of 12 Monkeys promises plenty of time-travel action and drama as the series takes the characters further back into the past than ever before. This new trailer gives us a glimpse at what the characters will be up to when the series returns for its final season.
The trailer highlights scenes set in different time periods, including the Old West and World War II. At the 12 Monkeys panel, showrunner Terry Matalas also teased that the show is "going to get medieval." There's also a strong focus on the show's main villain, the Witness, who was shockingly revealed to be Olivia (Alisen Down) in the season 3 finale. Olivia had been manipulating the characters throughout the series, and even pretended to be an ally in season 3. The trailer lets us see Olivia as she embraces her identity as the Witness, no longer seeking to hide her true intentions.
Right away, the trailer dives deep into the story of "the serpent" that was told to young Cole by his father during the season 3 finale when Cole discovered a note written by his mother. The tale of the serpent that eats his own tail appears to be a metaphor for time, and the demon encountered by the serpent is the Witness, who seeks to destroy time.
Though the trailer provides us with a good sample of the action we can expect from the ten-episode final chapter of the series, not much can be learned about what's in store for the characters as they deal with the repercussions of their battle with the Witness. The team was torn apart over the revelation that their greatest enemy was the son of Cole (Aaron Stanford) and Cassie (Amanda Schull). Their decision to hide it from the rest of the team, as well as their decision to protect their son despite his threat to time itself, only made things worse.
Just when their problems seemed irreconcilable, a stunning new twist put them all on the same side again. However, previous seasons indicate that situations on the show will never be that black-and-white. This was noted during the panel when it was stated that Cole and Cassie would have "a philosophical disagreement."
One thing we can be sure about is that the characters still have a long way to go, not only concerning their quest to stop the Witness, but also in working together as a team again. Matalas says that season 4 is about family. The characters have "lost the war and it will get much worse."
