Ep 2. One Night in October

In the Fringe season 4 episode 2, titled "One Night in October," the Fringe team investigates a series of murders that seem to be linked to a night in 1985, when Walter Bishop and William Bell participated in an experiment that had catastrophic consequences. The murders all occurred on the same date, and there are no apparent connections between the victims or their killers.

As the team delves deeper into the case, they discover that the murders are part of a larger pattern, and that a sinister force is behind them. Among the victims is a man who was killed in his apartment, but there are no signs of forced entry and nothing is missing. Another victim is a woman who was attacked by a man wielding a weapon that left no trace on her skin.

Meanwhile, in the alternate universe, Olivia Dunham and Lincoln Lee investigate a similar string of murders that occurred on the same date, but the differences between the two cases are striking. While the Fringe team deals with a seemingly supernatural force, the alternate universe's team finds evidence pointing to a government conspiracy.

As both teams struggle to make sense of the murders, the lines between the two universes continue to blur, and it becomes clear that the consequences of Walter Bishop and William Bell's experiment may be more far-reaching than anyone could have imagined.

Throughout the episode, the tension builds as the Fringe team races against time to solve the case and stop the murderer before they strike again. As the clues begin to come together, we see how the events of 1985 have led to the present-day crisis, and how the actions of a few individuals can have massive, unforeseen consequences.

Overall, "One Night in October" is a thrilling and suspenseful episode that showcases the best of Fringe's storytelling and character development. With its gripping storyline, complex themes, and masterful blend of science fiction and horror, it is a must-see for fans of the series.
