5. Life's a Mystery

Complete story — includes the ending

In Juárez, Sydney Snow ( Jonathan Scarfe ) escapes a lynching by killing the Fuentes Brothers, who had been intent on hanging him. Sydney flees, not noticing Marcos Fuentes ( Zak Santiago ) survived. Snow arrives in Cheyenne, claiming to be Cullen's war buddy. Although Cullen doesn't remember him, Cullen nonetheless houses Snow and vouches for him with Psalms to work on the crew. Snow divulges to Naomi, to Cullen's chagrin, an old war story where Cullen had killed scores of Union soldiers convalescing in a hospital. Later, Marcos arrives with his men. Snow not only kills Marcos in the general store, he also fires wildly and kills a young boy. When the store clerk confronts Snow, he's also killed. Naomi, hiding with the baby, is found by Snow, who is then stopped by Cullen, who contemplates whether or not to kill them. Meanwhile, Durant elicits Campbell's anger by flattening his government office. A decree stating the site has been approved for a roundhouse is handed to Campbell, who later vows to take over Cheyenne and then the railroad. Brigham Young ( Gregg Henry ) arrives at Fort Smith. In private, he appears to know The Swede is not Bishop Dutson by asking him about Cullen, Durant, and the railroad, but Young is willing to overlook the charade in order to facilitate the Mormons' expansion of their own railroad. After Jessup insults Mickey in the bar, Mickey later strangles him in an alley. Heckard, hinting to Durant that he and Jessup were lovers and believing Durant is Jessup's killer, attacks Durant viciously in the latter's railcar.
