Jason finds himself at a crossroads. He is forced to visit a former teammate, Theo, who has struggled significantly since leaving the service. This encounter serves as a "mirror," making Jason question his own longevity in the field and what his life looks like outside of being a tier-one operator.
Ray continues to grapple with the aftermath of his capture and torture. His "rearview mirror" involves facing the domestic reality of his trauma and how it affects his relationship with Naima and his children.
