Halo Season 2 has been leading up to Episode 4, “Reach”, since the beginning. The Covenant have invaded Reach, catching everyone off guard, including Master Chief John-117 (Pablo Schreiber), who tried to warn UNSC command and ONI in time. Episode 3 ended with a cliffhanger, and Episode 4 immediately plunges us into the action.
The episode opens with Vannak-134 (Bentley Kalu) feeding his pigeons on the roof, only to witness Covenant attacks destroying the city. Meanwhile, Master Chief and Perez are navigating the chaos, with Perez dealing with the loss of her family in a devastating explosion. Master Chief convinces her to join him in the fight.
In another storyline, Soren-066 (Bokeem Woodbine) and Dr. Halsey (Natascha McElhone) find themselves trapped together as the Covenant attacks escalate. They form an unlikely alliance to escape.
As Master Chief and Perez fight Covenant forces in the city streets, they are joined by fellow Spartans. The action is intense, with sacrifices made along the way. Halsey and Soren also face danger as they try to retrieve valuable assets from the facility.
Eventually, Master Chief and his team regroup, minus one member, and plan their next move. Meanwhile, Soren confronts Halsey about her past actions, leading to a pivotal moment in their dynamic.
