The idealistic path Billy the Kid seeks crumbles in "The Agony," the
heart-wrenching third episode of season 2. Witnessing the brutal murder of his
mentor, John Tunstall, throws Billy back into the violent vortex he desperately
wanted to escape.

The Burden of History
The episode acknowledges the limitations of historical fiction. While viewers with some historical knowledge can predict the narrative arc, Tom Blyth's portrayal of Billy remains captivating. The loss of a parental figure, a void left by his mother's death in season 1, is poignantly filled by Tunstall.
The Seeds of Conflict
Tunstall's fair business practices threaten the corrupt monopoly held by Major Murphy's "The House," backed by the manipulative Thomas Catron. This two-pronged attack – legal maneuvers by Catron and intimidation tactics by Jesse's gang – forces Billy to choose sides.
A Bond Forged and Broken
Despite their contrasting personalities, Billy and Tunstall form a strong connection. However, Tunstall's naivety and lack of stomach for violence become increasingly evident. His ill-fated attempt to appease Jesse by freeing him and his men backfires, and his subsequent decision to move his horses to a different farm proves disastrous.
A Deadly Mistake
Billy's suggestion to send riders ahead to scout for pursuers proves insufficient. Tunstall's sense of security leads him to stop for lunch, leaving him vulnerable. Jesse's gang ambushes the unsuspecting Tunstall, gunning him down before Billy can intervene.
Vengeance Consumes Billy
Witnessing his mentor's brutal death shatters Billy's remaining hope for redemption. His vow to kill Tunstall's murderers transcends legal boundaries, forcing Dulcinea to distance herself from him. This loss fuels Billy's return to outlaw ways. Despite a brief attempt to pursue justice through the courts, he resorts to horse rustling and the cold-blooded killing of unarmed men – actions that will undoubtedly undermine his cause in the coming war.
Looking Ahead
The episode leaves viewers with a sense of dread. Tunstall's death serves as a tipping point, plunging Billy deeper into violence and setting the stage for a brutal conflict. The question remains: Can Billy find redemption amidst the flames of vengeance?
